ABOUT US:
AI NEEDS A NEW INFRASTRUCTURE LAYER. WE'RE BUILDING IT AT MODAL.
Every era of computing brought new workloads that previous infrastructure couldn't support: mainframes, databases, and the cloud. Each time, the company that rebuilt the layer underneath defined the decade. AI is no different, except it touches everything instead of one slice, and the window to build the layer underneath it is open right now.
Our customers include category-defining companies like Ramp https://modal.com/blog/how-ramp-built-a-full-context-background-coding-agent-on-modal, Cognition, DoorDash, and Suno. They rely on Modal for instant GPU access, sub-second container starts, and native storage, so it's simple to serve low-latency inference, fine-tune models, and access production-ready sandboxes at scale.
We've passed $1B in annualized run rate, up 15x from a year ago. In October 2026 we raised a $750M Series D led by Accel at a $15.75B valuation.
Our team includes creators of popular open-source projects (e.g.,Seaborn https://github.com/mwaskom/seaborn,Luigi https://github.com/spotify/luigi), academic researchers, international olympiad medalists, and experienced engineering and product leaders with decades of experience.
THE ROLE:
We're looking for an Engineering Manager to lead a team of highly experienced engineers building the infrastructure that powers Modal's serverless GPU platform. This is a hands-on leadership role — expect to split your time between technical contribution and people management depending on what the team needs. You'll set direction, remove blockers, and build a strong engineering culture as your team tackles hard problems in distributed computing, large-scale data handling, and performance optimization.
WHO YOU ARE:
You're an experienced engineering leader who stays close to the work and builds alongside your team when it counts. You earn trust through technical depth, not title. You communicate clearly, help strong engineers move fast without cutting corners, and stay calm and pragmatic under pressure. You care as much about how your team gets to an answer as the answer itself.
RESPONSIBILITIES:
Team
- Recruit, hire, and grow a high-performing team of cloud platform engineers; run regular 1:1s focused on coaching, feedback, and career growth.
- Set clear performance expectations, hold a high bar, and build an environment where engineers do their best work.
- Foster a culture of ownership, accountability, and continuous improvement.
Technical Direction
- Drive day-to-day technical decisions through design reviews, code reviews, and architectural discussions.
- Translate the infrastructure roadmap into clear team priorities and milestones, and hold execution against them.
- Establish standards for reliability, performance, and operational excellence; ensure the team owns projects end-to-end, from spec through production.
- Push for good judgment on tooling and architecture, with a bias against unnecessary complexity.
Cross-Functional & Incident Leadership
- Partner with product and engineering to align infrastructure work with business priorities; represent your team's progress, capacity, and tradeoffs clearly to leadership.
- Serve as the escalation point for major incidents; drive resolution with urgency and ensure the team learns systematically, feeding those learnings back into infrastructure improvements.
REQUIREMENTS:
- 10+ years of industry experience, including 3+ years in a leadership role
- Track record building high-performance distributed systems at scale
- Strong background in cloud infrastructure
- Deep knowledge of low-level OS foundations (Linux kernel, file systems, containers, etc.)
- Proficiency in a systems-level language (Rust, C, C++, or Java)

ABOUT BASETEN
Baseten powers mission-critical inference for the world's most dynamic AI companies, like Cursor, Notion, OpenEvidence, Abridge, Clay, Gamma, and Writer. By uniting applied AI research, flexible infrastructure, and seamless developer tooling, we enable companies operating at the frontier of AI to bring cutting-edge models into production. We're growing quickly and recently raised our $1.5B Series F https://www.baseten.co/blog/announcing-our-series-f/, led by Altimeter Capital, Conviction Partners, and Spark Capital. Join us and help build the platform engineers turn to ship AI products.
THE ROLE
We’re looking for a customer-obsessed software engineer to come ship with us. You’ll own features like multi-node training and products like serverless reinforcement learning (RL) from conception to MVP (and from MVP to GA!). You’ll work through the stack, architecting solutions from API and UI down to our infrastructure layer. You’ll fine tune models yourself to develop an understanding of user workflows. You’ll work closely with research engineers leveraging state-of-the-art training techniques to build experiences that accelerate model development and solve for real pain points. If you’re excited to dive deep into the training, let’s talk!
THE PRODUCT
Take a look at what we’ve built so far:
- Overview of the product so far https://www.baseten.co/blog/baseten-training-is-ga/#training-is-now-ga
- Training docs overview https://docs.baseten.co/training/overview
- Story of the Training product https://www.baseten.co/blog/a-q-a-from-inference-to-training-the-inside-story-of-baseten-s-newest-product/
- Research we've done https://www.baseten.co/resources/research/
EXAMPLE INITIATIVES
- Checkpointing Pipeline: Our checkpointing pipeline starts with automated checkpointing, a feature that ensures that versions of models created during training are automatically backed up to the cloud. Users are able to then deploy checkpoints seamlessly into inference servers, providing point-and-click integrations into inference frameworks like vLLM and Baseten’s Inference Stack. This enables customers to quickly evaluate the performance of their checkpoints with real traffic.
- Multinode training: Multinode training enables customers to easily run training jobs across multiple compute nodes, enabling users to train large models like GLM 4.7 and DeepSeek. We’ve built deeply at the Kubernetes layer to ensure that scheduling, startup, inter-node communication, and shutdown happen seamlessly under the hood and as the user expects.
- Training DX: Customers come to train on Baseten because it helps them get to value fast. To do this, we ensure that the features we ship aren’t just fast, but are easy to iterate with. We enhanced Baseten’s metrics from pod-level GPU summaries to per-GPU and per-Node. We’ve built a CLI experience that caters to terminal users, and UI experiences that enable user to seamlessly manage their training jobs.
RESPONSIBILITIES
- Iterate like crazy
- Design ergonomic APIs and abstractions to model complex resources and lifecycles

Our fast-growing customer base includes hundreds of modern software companies building the next generation of enterprise-ready products.
ABOUT THE ROLE 💭
The Platform team builds the shared backend components and development systems that every WorkOS product, workflow, and team member depends on.
On the platform side, we build common backend capabilities used across WorkOS, including our events infrastructure, webhooks, email delivery, outbox-pattern queues, and more. These systems allow product teams to scale without rebuilding the same critical primitives. Because they sit on critical paths across our products, scalability, latency, consistency, reliability, and operational simplicity matter deeply.
On the productivity side, we build the systems that take code from an idea to production, including CI/CD, build and test infrastructure, deployment workflows, and internal tooling. As agents play a larger role in software development and increase the volume of code and concurrent changes, we are rethinking this platform to scale with that volume through safe execution, fast feedback, relevant context, and verifiable outcomes.
Our internal teams are our customers. Success means they can build and operate products faster, adopt shared capabilities instead of creating one-off solutions, and confidently delegate more work to agents.
WHAT YOU’LL WORK ON ✔️
- Design, build, and operate high-throughput, low-latency shared backend systems that preserve consistency and durability through retries, duplicates, reordering, partial failures, and high concurrency
- Create platform interfaces, abstractions, and paved paths with a clean developer experience that makes shared capabilities easy for product teams to adopt
- Rotate across and embed with product teams to experience their workflows directly, understand their friction, and use those insights to shape platform investments
- Map evolving product-team needs and collaborate with the Foundations team to introduce new systems and primitives, such as scalable search, database partitioning, and archival strategies
- Own and evolve our CI/CD, build, test, deployment, and release infrastructure to shorten feedback loops and make production changes safer
- Reimagine CI/CD for an agentic software development lifecycle by building isolated, reproducible, and verifiable execution environments, along with automated loops that allow agents to diagnose failures, update changes, rerun validation, and safely move work through review, deployment, and production verification
- Instrument the entire software development lifecycle and use metrics such as feedback time, CI reliability, deployment frequency, lead time, and change failure rate to identify bottlenecks and verify that platform investments improve engineering outcomes
- Own platform reliability end to end, including observability, capacity planning, incident response, root-cause analysis, and prevention
- Shape the long-term platform strategy with a high bar for introducing new infrastructure. Thoroughly evaluate vendors and existing solutions, make deliberate build-versus-buy decisions, and account for operational complexity, lock-in, migration cost, reversibility, and long-term ownership
WHAT WE’RE LOOKING FOR 🌟
- 8+ years of software development experience, with a track record of owning high-impact technical projects
- Experience building and operating distributed systems or platform services at scale, with a strong understanding of event-driven systems, queues, concurrency, idempotency, consistency, backpressure, retries, and failure recovery
- Experience building or operating CI/CD, build systems, test infrastructure, deployment platforms, or similar developer tooling
- A track record of designing platforms, frameworks, and tooling with a clean developer experience that makes complex capabilities easy for other engineers to adopt and operate
- Strong operational instincts across observability, capacity planning, incident response, and reliability
- Hands-on experience with AI coding agents, or a strong interest in building agentic CI/CD systems, verifiable execution environments, automated feedback loops, evaluations, and verification
- Exceptional pragmatism and technical judgment. You treat major infrastructure changes with the gravity they deserve and make deliberate, evidence-based decisions about when to build, buy, or improve an existing system
- Ability to move between long-term architecture and hands-on implementation while making thoughtful tradeoffs in an ambiguous environment
- Strong written and verbal communication skills, including experience documenting systems and influencing technical direction across teams
- Familiarity with TypeScript, Node.js, React, Postgres, AWS, Terraform, and queueing or streaming systems such as SQS and Kinesis is helpful, but not required
We expect strong depth in either distributed platform systems or developer infrastructure, along with an interest in working across both.

To achieve our mission of making programming more accessible around the world, we need our team to be representative of the world. We welcome your unique perspective and experiences in shaping this product. We encourage people from all kinds of backgrounds to apply, including and especially candidates from underrepresented and non-traditional backgrounds.
Location: Home Based - Americas
We are looking for enterprise sales people based in LATAM and fluent in Spanish. Colombia is currently the highest priority.
We deliver better open source from the data center to cloud and edge. Our Linux distribution Ubuntu is now the leading platform for public cloud compute, and the favorite platform for software engineers, data scientists and AI developers. Our mission is to accelerate the adoption and quality of open source globally, and our goal is to ship the most software on the planet by cores. A tidal wave of open source innovation is the next phase of the entire enterprise software industry, and we aim to be the most compelling way to ride that wave.
Our customers include Global 500 enterprises and startups. We are expanding our product range from the base operating system - Ubuntu - to full enterprise solutions in infrastructure and applications. We can deliver software defined storage, private cloud solutions, container runtime environments, as well as databases, message queues, identity, observability, analytics, machine learning and web publishing capabilities. Customers love the idea that they can get security compliance and support for everything open source from a single company. Our goal is to have more solutions on tap than any other vendor, and we have built unique capabilities to make that possible across every cloud, every class of compute and every category of application.
Canonical provides licensed enterprise software products, commercial support, managed services, consulting and training services to customers who are deploying Ubuntu or open source applications on the cloud, in their data center, or to the connected device and IoT ecosystem. We are just over 1,000 colleagues in 70+ countries and $250m in revenue, profitable, on a steady but relentless growth trajectory. We are almost entirely distributed, with leadership spread across many countries. We believe that talent is equally distributed across the globe, and we are excited to hire, develop, promote and ultimately trust a diverse group of exceptional leads to build the best, not biggest, enterprise software company.
We hire carefully and deliberately; our selection process is long and requires substantial work from applicants. It will take successful applicants three to six months to secure an offer. This is not a place to apply if you are in a rush to find a position, it is a worthwhile place to apply if you are ambitious and long-term in your thinking about your career and the dynamics which move the world forward. If you see clearly the rise of open source, and you understand the drivers of enterprise procurement and technical decision making, then you will understand why Canonical has such a tremendous long term advantage. You will also understand, given the ferocity of competition and the challenges of competing in a market of giants, that we have to set a very high bar for hiring and performance. In order to be a world leading company we select for exceptional ability as well as character, and then provide an environment which promotes teamwork and celebrates diligence, collaboration and effectiveness. All of those are easy to say but hard to do - at Canonical we are willing to be uncomfortable in pursuit of that excellence.
In building our sales team, we look for five things:
Empathy for the customer - a real understanding of customer needs, industry-specific challenges, and a desire to help customers solve their business problems
High intellect - the ability to learn quickly, understand very complex subjects, and communicate clearly to build trust and confidence
Passion for technology - a fascination with the state of the art from brilliant people solving hard problems, and fierce competition for large prizes
Teamwork - a willingness to help others, to collaborate well with people from different disciplines, and to balance personal and team ambitions
Energy - the drive to motivate oneself and others to achieve the best result for the team and our customers
Ubuntu is already very widely adopted which gives us a credible basis for conversations in the market. Nevertheless, it requires real work for sales professionals to build on that adoption to create trusted and profitable commercial relationships with the enterprises in their territory. Our product managers and marketing teams run campaigns to generate awareness, engagement and leads, but you will need to go beyond managing inbound interest to develop the potential of your territory. You will need judgement as to which industries and companies are ready to go deeper with open source and Canonical, and energy to develop relationships in advance of proven interest. We expect professional practice, territory and account planning, as well as clear, complete and continuous reporting on pipeline status and activity, using standard professional tools.
The successful candidate will carry an annual bookings quota within their assigned territory. They should be able to travel regionally for client engagement, industry conferences, and internationally for company events twice a year. They will be expected to demonstrate professionalism and effectiveness, to prospect accounts for new business, maintain and develop existing relationships, and work with colleagues and partners on account strategy. They must be comfortable selling enterprise software, open source, cloud, virtualization, container technologies and technical software solutions to senior levels of the enterprise.
