Analysis and Insight - Produce supplier spend and payment analysis, and AP ageing and working capital reporting to support cash management. - Identify opportunities to improve payment terms, purchasing controls and process efficiency, and support ad hoc finance reporting and analysis. Systems and Process - Use our spend and AP tooling, including its AI features, to drive touchless invoice processing. - Support the rollout of PO-based purchasing and three-way match as procurement volumes grow. - Support integrations between our spend tooling and ERP, and document processes and controls clearly as we build them. WHAT WE’RE LOOKING FOR - 2 to 4 years’ experience in finance operations, accounting or accounts payable, ideally within a fast-growing or multi-entity environment. - Experience with modern spend and AP platforms (for example Ramp, Payhawk or Tipalti) and ERP systems (SAP, NetSuite, Xero or similar). - Strong controls instincts, including accuracy, segregation of duties and a clean audit trail. - Comfortable with data and analysis, using spreadsheets and finance systems to spot trends, errors and opportunities. - Highly organised and process-driven, with the initiative to improve and document as you go. - Comfortable with high volume and ambiguity in a fast-scaling startup environment. - Ambition to grow beyond finance operations into broader accounting and finance responsibility. - An accounting qualification, or being on the journey towards one, is a plus and can be supported. WHAT WE OFFER - Competitive equity: stock options with meaningful upside as we scale. - 30+ paid days off, including 23 days of annual leave, all UK bank holidays, and additional company closure days (including Christmas to New Year shutdown). - Private healthcare, including virtual and in-person care. - Free daily breakfast, catered lunch, and snacks in-office. - Work at the frontier: collaborate daily with world-class engineers, researchers, and product experts building the next generation of AI and humanoid robotics. - Real ownership: direct access to leadership, meaningful input, and the ability to drive key initiatives from day one.

Location: London Workplace: OnSite ABOUT US Sierra is the leading platform for customer-facing AI agents, working with many of the world's biggest brands — including The GAP, Rocket Mortgage, SoFi, Sutter Health, and SoftBank — to transform how they serve customers and grow their businesses. We are primarily an in-person company based in San Francisco, with growing offices across North America, Europe, and Asia. We are guided by a set of values that are at the core of our actions and define our culture: Trust, Customer Obsession, Craftsmanship, Intensity, and a commitment to balancing Family along the way. These values are the foundation of our work, and we are committed to upholding them in everything we do. Our co-founders are Bret Taylor https://www.linkedin.com/in/brettaylor/ and Clay Bavor https://www.linkedin.com/in/claybavor/. Bret currently serves as Board Chair of OpenAI. Previously, he was co-CEO of Salesforce (which had acquired the company he founded, Quip) and CTO of Facebook. Bret was also one of Google's earliest product managers and co-creator of Google Maps. Before founding Sierra, Clay spent 18 years at Google, where he most recently led Google Labs. Earlier, he started and led Google’s AR/VR effort, Project Starline, and Google Lens. Before that, Clay led the product and design teams for Google Workspace. WHAT YOU'LL DO As an Agent Strategist https://sierra.ai/blog/agent-strategist-your-phd-in-applied-ai, you own how Sierra's AI agents come to life for our customers — from first pilot to a production agent handling thousands of conversations a day. You sit at the intersection of product, building agents and customer-facing work, and stay just as close to the technology as you are to the people you build for. You transform a customer's thorniest, highest-stakes problems into agents that measurably move their business. - Own the Agent Development Life Cycle https://sierra.ai/blog/agent-development-life-cycle. Take agents from initial scope through conversation design, tooling, and evaluation, to launch and continuous iteration in production — translating business goals into an agent that outperforms, and tuning relentlessly until it's the best version of itself in the real world. You'll have real ownership and autonomy over the outcome. - Be the trusted strategic advisor to enterprise leaders. Sit shoulder-to-shoulder with our customers' executives, understand what success actually means to their business, and shape the AI strategy that gets them there. - Partner with the customer's working teams day to day. Run working sessions, troubleshoot the agent as issues come up, and make the calls that keep the build on track for launch. - Directly impact product. Surface unmet needs from your customer work, and feed them back to research and platform to shape where Sierra goes next. EXAMPLE PROJECTS These are the kinds of projects that strategists on our team have worked on recently: - Scope and launch a subscription-retention agent for a large telecommunications or media company that consistently outperforms human agents at saving at-risk customers. - Stand up an agent for a commerce customer that troubleshoots a broken device end-to-end and personalizes product recommendations in the same conversation. - Redesign the conversation flows for a financial services agent so it can handle complex, regulated interactions — and convert a pilot into a multi-team production deployment. See our financial services blog https://sierra.ai/blog/five-ways-to-use-ai-agents-financial-services for examples. - Partner with product on a net-new capability — a new agent architecture or self-service tooling — using a live customer as the design partner. - Define the evaluation and quality bar for a new agent, then use those metrics to drive a measurable lift in outcome https://sierra.ai/blog/outcome-based-pricing-for-ai-agents week over week. WHAT YOU'LL BRING - Customer obsession. Genuine energy being in front of customers — understanding their business and needs, thriving in complex organizations, and building trusted relationships. - Communication. Clear, direct, and persuasive across technical and non-technical audiences. - Strategic problem-solving in ambiguity. Strong analytical and critical-thinking skills to break down complex problems, spot risks early, and adapt as things change fast. - Technical aptitude.

We are primarily an in-person company based in San Francisco, with growing offices across North America, Europe, and Asia. We are guided by a set of values that are at the core of our actions and define our culture: Trust, Customer Obsession, Craftsmanship, Intensity, and a commitment to balancing Family along the way. These values are the foundation of our work, and we are committed to upholding them in everything we do. Our co-founders are Bret Taylor https://www.linkedin.com/in/brettaylor/ and Clay Bavor https://www.linkedin.com/in/claybavor/. Bret currently serves as Board Chair of OpenAI. Previously, he was co-CEO of Salesforce (which had acquired the company he founded, Quip) and CTO of Facebook. Bret was also one of Google's earliest product managers and co-creator of Google Maps.

WHAT YOU'LL DO As an Agent Strategist https://sierra.ai/blog/agent-strategist-your-phd-in-applied-ai, you own how Sierra's AI agents come to life for our customers — from first pilot to a production agent handling thousands of conversations a day. You sit at the intersection of product, building agents and customer-facing work, and stay just as close to the technology as you are to the people you build for. You transform a customer's thorniest, highest-stakes problems into agents that measurably move their business. - Own the Agent Development Life Cycle https://sierra.ai/blog/agent-development-life-cycle. Take agents from initial scope through conversation design, tooling, and evaluation, to launch and continuous iteration in production — translating business goals into an agent that outperforms, and tuning relentlessly until it's the best version of itself in the real world. You'll have real ownership and autonomy over the outcome. - Be the trusted strategic advisor to enterprise leaders. Sit shoulder-to-shoulder with our customers' executives, understand what success actually means to their business, and shape the AI strategy that gets them there. - Partner with the customer's working teams day to day. Run working sessions, troubleshoot the agent as issues come up, and make the calls that keep the build on track for launch. - Directly impact product. Surface unmet needs from your customer work, and feed them back to research and platform to shape where Sierra goes next. EXAMPLE PROJECTS These are the kinds of projects that strategists on our team have worked on recently: - Scope and launch a subscription-retention agent for a large telecommunications or media company that consistently outperforms human agents at saving at-risk customers. - Stand up an agent for a commerce customer that troubleshoots a broken device end-to-end and personalizes product recommendations in the same conversation. - Redesign the conversation flows for a financial services agent so it can handle complex, regulated interactions — and convert a pilot into a multi-team production deployment. See our financial services blog https://sierra.ai/blog/five-ways-to-use-ai-agents-financial-services for examples. - Partner with product on a net-new capability — a new agent architecture or self-service tooling — using a live customer as the design partner. - Define the evaluation and quality bar for a new agent, then use those metrics to drive a measurable lift in outcome https://sierra.ai/blog/outcome-based-pricing-for-ai-agents week over week. WHAT YOU'LL BRING - Customer obsession. Genuine energy being in front of customers — understanding their business and needs, thriving in complex organizations, and building trusted relationships. - Communication. Clear, direct, and persuasive across technical and non-technical audiences. - Strategic problem-solving in ambiguity. Strong analytical and critical-thinking skills to break down complex problems, spot risks early, and adapt as things change fast. - Technical aptitude.

Location: United States (Remote) GiveWell’s mission is to help people in need as much as we can by researching the most cost‑effective ways to save and improve lives, sharing our work openly, and directing donations to the programs we believe will do the most good. Our work, which focuses on global health and well-being, is funded by tens of thousands of donors who rely on our research to inform their giving. We’ve grown from directing $1.5 million in 2010 to directing more than $400 million in 2025. We anticipate our total grantmaking is likely to approach or even exceed $1 billion this year, and we are working toward a future that could be several times that scale. Through years of deliberate groundwork, we’ve been growing our research capacity and scope in order to direct substantially more funding to the most impactful opportunities we can find. We’re hiring a Senior Communications Officer, Media & Public Affairs to lead how GiveWell’s work is represented in the media and in public conversations. You will set our strategy, build trusted relationships with journalists and other influential voices, pursue opportunities that increase understanding of GiveWell’s work, and lead our external response in fast-moving situations. This role will lead a small and growing team. This is one of three new communications leadership roles, alongside a Senior Communications Officer, Strategic Communications and a Senior Communications Officer, Editorial & Production . About the role Both our research and impact are expanding . Last year, we directed more than $400 million to highly cost-effective programs that save and improve lives. This year, we expect our grantmaking to approach, and possibly exceed, $1 billion. To build toward the communications capacity this next stage requires, we are rapidly expanding our team. The three Senior Communications Officers will work together on many projects to support GiveWell’s communications needs, while working closely with other leaders across our organization. Each leader will own their function, but much of the work that matters most—like team strategies, major initiatives, partnership campaigns, and how we present the organization as a whole—will involve all three. We will expect this group to set shared priorities and work closely together to achieve the team’s goals. In this hands-on leadership position, you’ll own how and where GiveWell engages in media and public conversations, with end-to-end responsibility for this emerging function. You’ll set its strategy, hire and develop its people, build its systems, and personally own its hardest and most consequential work. This is an opportunity to build, not just inherit, an important function at a critical point in GiveWell’s development. You’ll start with a small team and grow it over time. While this role is set at the Senior Communications Officer level, we may consider hiring an exceptional candidate as a Communications Director—with greater expectations, responsibilities, and compensation. What You'll Do As Senior Communications Officer, Media & Public Affairs, you will combine long-term strategy and relationship-building with the ability to respond quickly and exercise sound judgment in sensitive or fast-moving situations. Specific duties will include: Set GiveWell’s strategy across media, thought-leader engagement, online communities, public forums and events, and other earned communications opportunities—including deciding where and when GiveWell should participate and overseeing those engagements. Build and maintain high-trust relationships with journalists, editors, podcast hosts, event organizers, thought leaders, subject-matter experts, and other influential external stakeholders. Identify, develop, and pitch substantive stories, event opportunities, and thought-leadership ideas that extend understanding of GiveWell’s work. Own inbound media engagement, including situations that require rapid responses, close coordination with subject-matter experts, and careful judgment about what GiveWell can responsibly say—and about which responses need escalation. Build and maintain GiveWell’s readiness for sensitive or fast-moving situations, monitor emerging issues in media and public conversations, and lead our external response when needed in partnership with others. Advise GiveWell’s leadership on external opportunities and relationships, and prepare senior leaders and subject-matter experts for interviews, speaking engagements, and other public appearances. Exercise sound judgment about when and how GiveWell should enter public conversations, including evaluating likely value, reputational considerations, and communications risks. Evaluate and help shape public-facing communications partnerships, advising on which opportunities GiveWell should pursue and how we should participate. Serve as a spokesperson for GiveWell in select media interviews, events, and other public forums, communicating our perspective clearly, accurately, and with sound judgment. Work with grantees and other partners on press releases and other media-facing communications involving GiveWell or our shared work. Manage and develop one or two team members initially, and build the relationships, systems, and additional capacity the function will need over time. About You You are skilled at using communications to help people understand complex ideas, build trust, and take action. You are comfortable being accountable for outcomes, making consequential decisions with limited oversight, and knowing which decisions genuinely require escalation. You are energized by intellectually demanding work, and the challenges of creating engaging communications within a careful and precise style. You can engage deeply with GiveWell’s research, and you are comfortable understanding and communicating about data in detail. You have a long track record of getting up to speed quickly on complex subject matter and carefully communicating to a very high standard. You can build a compelling narrative that is entirely factual, representing what is known and unknown without overstating or hedging into vagueness—and you find the idea of working with GiveWell’s exacting communications standards exciting rather than limiting. Your background includes significant experience leading communications in complex, high-stakes environments. This should include 10+ years of experience in media relations, thought leadership, and public engagement. You have deep experience owning that work end to end, not just contributing to it. You’ve remained a hands-on leader who enjoys the work itself, as well as the strategy and systems behind it. You know how journalists, influential voices, events, and other public forums shape how organizations and ideas are understood. You have a demonstrated ability to build meaningful external relationships, identify opportunities worth pursuing, personally represent an organization’s perspective, and navigate public-facing situations in which context is limited, timelines are short, and judgment matters. Much of this should be work you executed yourself, in addition to work you directed. Experience in settings where precision and credibility were at least as important as reach is a strong signal of fit. In addition to demonstrated expertise in the duties listed above, you should have: Exceptional communications judgment, including the ability to understand audience, context, risk, timing, and the underlying substance of a message. Excellent written and verbal communication skills and the ability to quickly make complex ideas clear and compelling without sacrificing rigor or nuance. A track record of building and leading: you have created or substantially rebuilt a team or function—not only run ones you inherited—and you have hired, developed, and managed people. Recent, hands-on excellence at your craft: you can point to work from the past few years that you personally produced or substantially shaped. Experience producing communications that are direct and factual while being engaging and effective with their target audiences—work that succeeds through substance and clarity rather than embellishment. Intellectual curiosity and the ability to engage deeply with GiveWell’s research and ideas, even without prior experience in our giving areas. Experience advising executives or other senior decision-makers directly. Strong alignment with GiveWell’s mission and values, including truth-seeking, transparency, and a commitment to communicating accurately and thoughtfully. We also think these qualities will help you do well in the role and at GiveWell: People who can develop a strong point of view and hold it with confidence, but remain genuinely open to challenge, new information, and better ideas. Self-starters who take ownership, are comfortable creating structure in an evolving environment, and can make thoughtful decisions without always having complete information. People who are proactive and anticipatory, who identify opportunities, risks, bottlenecks, and communications needs before they become obvious. Collaborative leaders who raise the quality of the work around them and build strong relationships across teams. People who coordinate well with peers, resolve dependencies and disagreements, and make shared work clearer rather than more complicated. Key Questions & Information What are some of the reasons I might not like this role? You want to step into a mature function with established systems, rather than build one while you run it. You do best with clear direction and established priorities. We’ll expect you to set most of your own, make most decisions yourself, and reach substantial autonomy within your first six months. You prefer advising on communications to producing and being accountable for them. You want sole ownership of an organization’s overarching communications strategy and brand. At GiveWell, the CEO and executive team owns that direction; you would help shape it and lead your function within it. You want to lead a large team from day one. This team is small today, and much of the most difficult work will be yours to do directly. You find standards of precision and understatement limiting and frustrating. We work extremely hard to only communicate accurately what we know and what we don’t. Can I apply to more than one of the Senior Communications Officer roles? You can, but most people shouldn’t. We’re looking for deep expertise in these areas, and we expect most candidates with required expertise will be a clear fit for a single role. If you’re one of the few with real depth in more than one area, apply to both and tell us why. Otherwise, apply for the role you are most qualified for, and we’ll let you know if we think another role might suit you better. What does this interview process entail? We’ll use a combination of interviews, written exercises, and work trials to assess the qualities described above. We’ll share more specific details if we invite you to move forward to any of the following stages, but our current plan will likely include the following: Application Interview with a member of the Talent Acquisition Team Compensated work trial with a set maximum number of hours Interview with GiveWell's Chief of Staff to the CEO Values interview CEO interview and References Note that you don’t need to submit a cover letter.

Location: United States (Remote) GiveWell’s mission is to help people in need as much as we can by researching the most cost‑effective ways to save and improve lives, sharing our work openly, and directing donations to the programs we believe will do the most good. Our work, which focuses on global health and well-being, is funded by tens of thousands of donors who rely on our research to inform their giving. We’ve grown from directing $1.5 million in 2010 to directing more than $400 million in 2025. We anticipate our total grantmaking is likely to approach or even exceed $1 billion this year, and we are working toward a future that could be several times that scale. Through years of deliberate groundwork, we’ve been growing our research capacity and scope in order to direct substantially more funding to the most impactful opportunities we can find. We’re hiring a Senior Communications Officer, Editorial & Production to lead the editorial quality and production of GiveWell’s communications. You will set the editorial bar, build the people and systems needed to produce excellent work consistently and at increasing scale, and personally shape some of our most complex and consequential content. This role will lead a small and growing team. This is one of three new communications leadership roles, alongside a Senior Communications Officer, Strategic Communications and a Senior Communications Officer, Media & Public Affairs . About the role Both our research and impact are expanding . Last year, we directed more than $400 million to highly cost-effective programs that save and improve lives. This year, we expect our grantmaking to approach, and possibly exceed, $1 billion. To build toward the communications capacity this next stage requires, we are rapidly expanding our team. The three Senior Communications Officers will work together on many projects to support GiveWell’s communications needs, while working closely with other leaders across our organization. Each leader will own their function, but much of the work that matters most—like team strategies, major initiatives, partnership campaigns, and how we present the organization as a whole—will involve all three. We will expect this group to set shared priorities and work closely together to achieve the team’s goals. In this hands-on leadership position, you’ll own the editorial quality and production of GiveWell’s communications, with end-to-end responsibility for this emerging function. You’ll strengthen its standards, hire and develop its people, build its systems, and personally own its hardest and most consequential work. This is an opportunity to build, not just inherit, an important function at a critical point in GiveWell’s development. You’ll start with a small team and grow it over time. While this role is set at the Senior Communications Officer level, we may consider hiring an exceptional candidate as a Communications Director—with greater expectations, responsibilities, and compensation. What You'll Do As Senior Communications Officer, Editorial & Production, you will be responsible not only for the quality of individual pieces but also for creating a content operation that can prioritize effectively, manage dependencies, use its resources well, and deliver reliably. This will require both senior editorial judgment and strong operational leadership. Specific duties will include: Own the editorial quality and production of GiveWell’s communications, ensuring that our work is clear, accurate, useful, carefully reasoned, and delivered on time. You will serve as GiveWell’s senior editor for our communications content, with responsibility for returning or correcting work that does not meet our editorial bar. Build and manage the workflows, editorial standards, review processes, and production systems that allow GiveWell to create consistently excellent content at increasing scale. Lead planning, prioritization, and resource allocation for GiveWell’s owned-content portfolio, managing dependencies and moving complex projects from concept through publication. Uphold GiveWell’s voice and editorial standards across everything we publish, and help colleagues across the organization write within them. Own the development of GiveWell’s recurring communications and reporting products, turning established priorities and messaging into clear, accurate content. Personally create, edit, or substantially shape our most complex, sensitive, or high-priority content. Oversee GiveWell’s website content operations, including the people and processes responsible for routine updates and publishing, so that the site remains accurate, current, and consistent with our editorial standards. Serve as a senior editorial and production partner to teams across GiveWell, helping shape high-priority projects early, determine the right format and production approach, and establish clear roles, review paths, and timelines. Oversee the production of design, visual, and multimedia assets across GiveWell’s channels, and the internal team and external contractors who create them. Manage and develop one or two team members initially, and determine how the function’s team and capabilities should grow over time. About You You are skilled at using communications to help people understand complex ideas, build trust, and take action. You are comfortable being accountable for outcomes, making consequential decisions with limited oversight, and knowing which decisions genuinely require escalation. You are energized by intellectually demanding work, and the challenges of creating engaging communications within a careful and precise style. You can engage deeply with GiveWell’s research, and you are comfortable understanding and communicating about data in detail. You have a long track record of getting up to speed quickly on complex subject matter and carefully communicating to a very high standard. You can build a compelling narrative that is entirely factual, representing what is known and unknown without overstating or hedging into vagueness—and you find the idea of working with GiveWell’s exacting communications standards exciting rather than limiting. Your background includes significant experience leading communications in complex, high-stakes environments. This should include 10+ years of experience leading editorial and content-production work, setting and maintaining editorial standards, managing writers and editors, and building systems that produce consistently high-quality work. You have deep experience owning that work end to end, not just contributing to it. You’ve remained a hands-on leader who enjoys the work itself, as well as the strategy and systems behind it. You are a precise editor of complex or technical content: you read text literally and carefully, and you notice when a claim isn’t supported by the evidence behind it. You should be able to combine high standards for individual work with the operational judgment needed to prioritize, allocate resources, manage complex production, and increase capacity over time. You should understand how content is developed through writing, editing, design, audio, graphics, websites, and other formats—even if you are not personally an expert in every medium. In addition to demonstrated expertise in the duties listed above, you should have: Exceptional communications judgment, including the ability to understand audience, context, risk, timing, and the underlying substance of a message. Excellent written and verbal communication skills and the ability to quickly make complex ideas clear and compelling without sacrificing rigor or nuance. A track record of building and leading: you have created or substantially rebuilt a team or function—not only run ones you inherited—and you have hired, developed, and managed people. Recent, hands-on excellence at your craft: you can point to work from the past few years that you personally produced or substantially shaped.

We are a dynamic, collaborative team passionate about AI and its potential to transform society. Our diverse workforce thrives in competitive environments and is committed to driving innovation. Our teams are distributed between Europe, North America, Asia and the Middle East. We are creative, low-ego and team-spirited. THE ROLE Mistral is looking for AI Scientists with deep expertise in engineering sciences and machine learning to push the frontier of AI-accelerated simulation. Within AI4Engineering Science, you will research and train foundational physics models which are substantially more capable than what exists today and can be fine-tuned for downstream applications by both customers and internal teams. You will work across the full research stack: curating high-fidelity simulation datasets, designing and training novel model architectures, and rigorously evaluating them against real engineering validation standards. Working closely with the broader research organization, you'll ensure the foundation models you build are general enough to become the backbone of many downstream products, not just a single point solution. This role builds on a strong, world-class foundation, and the goal is to take it further. You'll work one vertical at a time toward foundation models that genuinely transfer and fine-tune across engineering tasks, with high-quality simulation data pipelines, physics-based evaluation, and uncertainty / out-of-distribution estimation as first-class concerns. There's no inherited playbook for most of what's left to do: you'll help define the architectures, training strategies, and validation standards the team builds on, not just extend an existing one. WHAT YOU WILL DO - Research and train novel foundation models for physics simulation, pushing past today's state of the art in accuracy, generalization, and scale - Design and run large-scale simulation campaigns using domain-specific solvers to build the high-fidelity datasets foundational physics models need - Investigate architectures and training strategies (e.g. multi-fidelity training, pretraining objectives, scaling behavior) that let a single foundation model transfer and fine-tune well across diverse engineering tasks - Rigorously evaluate model coverage, accuracy, and robustness against industry validation standards, and diagnose failure modes arising from data gaps or architecture limitations - Stay on top of the latest developments in the scientific community and contribute to Mistral's standing at the frontier of AI-for-engineering research WHAT WE'RE LOOKING FOR - PhD or Master's in CS/AI or an engineering science: Mechanical Engineering, Electrical Engineering, Computational Fluid Dynamics, Structural Mechanics, EDA, Semiconductor Engineering, or a related field - Strong, hands-on machine learning expertise with a deep understanding of model architectures, training dynamics, and evaluation methodology is core to this role - You have developed ML methods for simulation or surrogate modelling - You write clean, readable Python code and are comfortable in Linux/HPC environments - Fluent English with excellent communication skills, able to explain technical simulation and ML concepts to both engineering and non-technical audiences - Self-directed, you don't need detailed roadmaps to make progress - Low-ego, collaborative, and eager to learn at the intersection of simulation and ML - Demonstrated success through industrial projects, academic work, or personal projects IT WOULD BE GREAT IF YOU - Have industrial or academic experience with simulation solvers (e.g. OpenFOAM, LS-DYNA, ANSYS, COMSOL, Abaqus, Fluent, STAR-CCM+, PowerFlow, NekRS, Tau/CODA, JAX-Fluids, or equivalent; Cadence/Synopsys/Siemens EDA or equivalent) - Have experience automating large-scale simulation campaigns on HPC clusters - Have contributed to a large open-source or industry codebase - Have publications in engineering or ML venues (AIAA, ASME, JFM, NeurIPS, ICLR, etc.) WHAT WE OFFER We offer a comprehensive benefits package designed to support your well-being, growth, and work-life balance. Benefits vary by country and may include healthcare coverage, parental leave, retirement plans, relocation support, wellness programs, meal and transportation allowances, and other location-specific perks.

We partner with enterprises tackling the hardest problems across high-stakes industries like finance, manufacturing, defense, healthcare, and the public sector, co-creating customized AI systems that they can run on their terms. We are a dynamic, collaborative team passionate about AI and its potential to transform society. Our diverse workforce thrives in competitive environments and is committed to driving innovation. Our teams are distributed between Europe, North America, Asia and the Middle East. We are creative, low-ego and team-spirited. The Role Mistral is looking for AI Scientists with deep ML expertise and hands-on engineering experience to expand what our agentic tools can do across the engineering lifecycle — CAE (CFD, FEA, etc.) and EDA/Semi. Working within the AI4Engineering Science team, your core work is building the pre and post-training data for Mistral's LLMs to reason about and execute real engineering tasks. Because Mistral trains its own frontier LLMs, the data and verifiers you design ship directly into models you can hold, a rare position, and the core of the job. Alongside this, you'll help shape the agent architectures and harness that let these models operate reliably inside multi-step engineering workflows, not just answer isolated questions. You'll work closely with domain experts across CAE and EDA or other domains to ground this work in how engineers actually work, and with the broader research team to translate that domain grounding into training signal and evaluation benchmarks that measure genuine task competence. This is early-stage work, and that's the point: you'd be joining at the foundation, shaping the data, verifiers, and agent scaffolding that decide whether these systems become reliable or stay demo-grade. There's no inherited playbook, you'll help define what good looks like, and your work will set the direction the team builds on rather than extend an existing one. What you will do - Design pretraining, SFT, and RL data for engineering tasks across CAD, CAE, and semiconductor/EDA - Define verifiers and evaluation criteria that capture what "correct" and "high-quality" actually mean for each engineering task, beyond surface-level plausibility - Design and improve agent architectures and harnesses: how models plan, call tools, recover from errors, and chain steps together across long-horizon engineering workflows - Build evaluation benchmarks and diagnostic tooling to identify where models fail on engineering tasks, and trace those failures back to gaps in data, reward design, or agent scaffolding - Collaborate with domain experts across CAE and EDA or other domains (and the science and solutions teams more broadly) to identify which engineering workflows are highest-value to target next - Contribute to Mistral's broader pre and post-training research, sharing findings and methodology across the science organization What we're looking for - Fluent English with excellent communication skills, able to explain technical ML and engineering concepts to both engineering and non-technical audiences - Deep, hands-on machine learning expertise, particularly LLM development - Demonstrated experience running, debugging, and validating real engineering workflows in at least one of CAD, CAE, semiconductor simulation, or EDA - You write clean, readable Python code and are comfortable in Linux/HPC environments - Self-directed, you don't need detailed roadmaps to make progress - Low-ego, collaborative, and eager to learn at the intersection of engineering and ML It would be great if you - Have experience building or fine-tuning agentic systems (tool use, multi-step planning, agent orchestration frameworks) - Have experience with reward modeling, RLHF/RLAIF/RLVR, or preference-based training - Have industrial or academic experience with CAE or EDA tools (e.g. SolidWorks, CATIA, Fluent, Abaqus, LS-DYNA, STAR-CCM+, Cadence/Synopsys/Siemens EDA tools) - Have contributed to a large open-source or industry codebase - Have publications in engineering and ML venues (NeurIPS, ICLR, JFM, AIAA, etc.) WHAT WE OFFER We offer a comprehensive benefits package designed to support your well-being, growth, and work-life balance.
