Location: Remote Workplace: remote We're looking for a Senior Backend Engineer to join our backend team at Zerion. This team builds and evolves the backend systems at the core of our products and customer-facing solutions. In this role, you'll design and operate distributed systems, work with Web3 infrastructure, and collaborate closely with product, support, and the clients building on our API to deliver reliable, scalable solutions. We value strong ownership, thoughtful system design, and a high bar for code quality. If you enjoy building solid systems, moving fast without cutting corners, and using AI as a core part of how you work, you'll feel right at home with us. What You’ll Do Design, build, and maintain scalable distributed backend systems powering platform and product capabilities. Own backend services end-to-end : from architecture and implementation to monitoring and long-term reliability. Take part in the team's on-call rotation . When a service breaks in production, you respond, find the cause, fix it, and make sure it doesn't happen again. Work closely with product and engineering peers to actively shape product decisions — not just execute specs. Scope solutions with the clients building on our API: turn a vague request into a concrete proposal, and the proposal into a plan the team can build. Build and evolve Web3 platform backend components , including protocol integrations, support for newly emerging blockchain networks, and reliable interactions with smart contracts. Ensure high standards of code quality , performance, security, and observability. Operate comfortably in a fast-paced startup environment , balancing speed and correctness. Use AI as a core part of your engineering workflow — designing, reviewing, debugging and shipping with it. This is how the team works day to day, not an experiment we're running. Contribute to technical discussions , reviews, and mentorship within the engineering team. What We’re Looking For 5+ years of experience designing and building distributed backend systems . Strong knowledge of algorithms, data structures, and software design patterns . Comfortable working in a fast-paced startup environment . Strong desire to actively contribute to product evolution , not just implementation. Comfortable working directly with customers — hearing a vague problem and coming back with a concrete proposal. Hands-on, daily use of AI in your engineering work . You should be able to talk concretely about where it has changed how you build, and where you've learned not to trust it. High standards for code quality, system reliability, and user experience — you care about getting it right, not just getting it done. Strong ownership mindset — you take responsibility for outcomes, not just tasks. Clear and proactive communication in a distributed team. Pragmatic decision-making: knowing when to move fast vs. go deep . Ability to learn quickly and adapt . Technical Skill Set Excellent knowledge of Golang is a plus, not a blocker. Experience with containerized systems : Docker & Kubernetes. Experience with databases : SQL: Postgres NoSQL: MongoDB, Cassandra Experience with monitoring and observability tools : Sentry, Prometheus, Grafana. Hands-on experience with AWS (Amazon Web Services) . Experience with Python 3 . Comfort experimenting with and integrating AI-assisted workflows into daily engineering work. Bonus Points Hands-on Web3 experience: Blockchain systems, dApps, Smart contracts. Prior experience in a startup environment that emphasizes trust and autonomy . Located in time zones close to Europe for smoother collaboration. Collaborative mindset and respect for different perspectives.

Location: Remote Workplace: Remote SENIOR LIFECYCLE MARKETING MANAGER ABOUT WISTIA Making videos is easy. Making them work for your business? That is where Wistia shines. Our end-to-end platform gives businesses the tools to create, host, share, and analyze videos and webinars, all in one place. Our mission? To be the go-to video and webinar platform for businesses. And we know that mission starts with a team that feels valued, supported, and empowered to do their best work.     WHY THIS ROLE MATTERS The Senior Lifecycle Marketing Manager will play a critical role in helping our users discover, adopt and realize ongoing value with our product and features. This role will combine strategic thinking with analytical rigor and exceptional execution to serve a wide range of customers with unique needs, delivering the right message at the right moment. This role will identify opportunities through customer insights and product data, design sophisticated lifecycle programs, lead customer engagement strategies for new products and features, and continuously evolve the user experience through experimentation. You’ll partner closely with Growth Product, Product Marketing, Content, Demand Generation, Customer Success and more to shape what content gets created based on what the lifecycle program needs, connect what happens next when someone clicks an email and lands in the product, and build customer delight programs that turn satisfied users into advocates for the brand. Who You'll Work With: This role reports to our Senior Director of Demand Generation, and partners closely with the Growth Marketing, Content, Marketing Operations, Growth Product, Demand Generation and Customer Success teams. What It's Like Working on This Team: This is a hands-on, high-ownership IC role that will own the strategy and the execution. You'll be the person in the room asking whether something is actually right for the person receiving it, not just convenient for an upcoming initiative, and you'll proactively mine the database for what's missing: which segments are underserved, which lifecycle moments have no coverage, where we're leaving user potential on the table. While your primary, initial execution is email, your thinking extends beyond that, asking what happens after the click and flagging when a complementary channel, in-product moment, or webinar should be running alongside it. This role will leverage AI to meaningfully scale what they are able to do — accelerate experimentation, sharpen segmentation, find patterns in the database faster than any manual process could — and bring what you learn back as a resource for the broader marketing team, not just apply it to your own work. You will regularly translate what you are seeing in customer behavior into input that shapes what the rest of marketing invests in next. - Why is this role exciting? The lifecycle program has strong foundations ready for a dynamic and more personalized approach that’s connected to how users actually grow with Wistia. You will not be executing someone else's playbook; you will be building the next one. You’ll partner with Product Growth and other marketing teams to create key touchpoints with our user base and have ownership of one of marketing's highest-leverage channels at a company with a loyal, engaged customer base and a product that delivers real value. - How does it directly support Wistia's mission? Wistia's mission is to be the go-to video and webinar platform for businesses. This role will help users realize that value by discovering what the product can do, deepening how they use it, and understanding what Wistia can mean for their business long-term. You will be building and influencing the engine that makes those connections happen. - What interesting challenges will candidates tackle? Evolving a maturing email program toward trigger-based, behavior-driven lifecycle marketing takes real craft and cross-functional reach. You will shape what content gets created, work with product and growth teams on the infrastructure that enables personalization at scale, and use AI to do things that were not previously possible with a lean team. The challenge is not just technical — it is also about building the internal relationships and trust that let you influence how the whole organization thinks about engaging its users. Work Environment: Remote — open to candidates anywhere in the US.     KEY RESPONSIBILITIES - Deeply understand our users and our product to help them succeed and grow - Own the strategy and execution of 1:many and 1:few lifecycle programs, primarily through email, focused on driving product adoption, feature awareness, and cross-sell/purchase readiness across trial and customer audiences — setting users up for the expansion moments that matter, upstream of the transactional triggers. - Build and evolve a trigger-based, behavior-driven email program that supports what users are actually doing in the product. - Proactively mine and analyze our existing database for opportunities: identify underserved segments, under-engaged users, and untapped lifecycle moments that email can address, and build programs around what you find. - Develop a customer delight program to reward and celebrate our customers for their success, turning them into advocates for our brand. - Partner closely with Content to identify gaps and shape what gets created based on what the lifecycle program needs to drive adoption and awareness. Yes, you’ll use existing assets, but also actively influence the content roadmap. - Partner with Events, Webinar, and Product Marketing stakeholders to ensure lifecycle email is integrated with launches, live programming, and feature releases and vice versa. When a feature ships or a webinar goes live, this person should already have a lifecycle angle ready. - Work alongside Marketing Ops as a partner on HubSpot strategy and architecture, having input into how the platform is structured and maintained to support lifecycle goals. - Leverage AI tools to scale the sophistication and output of the email program in the short term while also planning ahead for what will be needed in the future. - Define and track KPIs tied to adoption, engagement, and cross-sell readiness. Translate those signals into input for the broader marketing team by surfacing what the data tells us about user behavior, content needs, and where we are leaving value on the table. - Collaborate cross-functionally with Content, Growth Marketing, Growth Product, Marketing Ops, and Customer Success to ensure the email program is working in concert with the broader GTM motion and that your insights about the customer lifecycle are actively shaping how the team operates.     WHAT WE'RE LOOKING FOR - 9+ years of email and lifecycle marketing experience at a B2B SaaS company, with a consistent track record of owning strategy and program outcomes — not just execution. - You may have managed a team at some point in your career, and you are choosing to stay hands-on. You know your leverage is in your craft, your systems, and your ability to scale through smart use of AI — not headcount — and you have built your career around that. - You are already using AI tools in meaningful, practical ways to scale output and program sophistication — from content generation to segmentation logic to experimentation velocity. You bring that muscle into this role and keep pushing it forward. - Deep HubSpot expertise: you can architect segmentation, automation workflows, and dynamic content at a program level, and you are comfortable co-owning the platform with an Ops partner rather than operating within someone else's setup. - A strong cross-functional influencer, particularly with Content, Events, Webinars, Product Marketing, and Growth Product teams that produce things the lifecycle program should be amplifying and integrating. - You know how to identify what the lifecycle program needs, build alignment with partners who have their own priorities, and get results without direct authority. - A genuine user advocate — you think about what is right for the person receiving the email, not just what is useful for the business sending it, and that instinct makes the programs you build more effective. - Analytically sharp: you can look at funnel and engagement data, identify where email can move the needle, and build a compelling case for what to prioritize next. - Experience with adoption and engagement-focused programs — you think about email beyond acquisition and conversion and understand how to use it to build product habits and deepen customer relationships over time. - Experience with PLG or product-led growth motions — trial activation, feature adoption signals, self-serve upgrade behavior — is a meaningful plus.     WHY YOU'LL LOVE WORKING AT WISTIA At Wistia, we are building the leading video platform for small and medium B2B businesses, and we know that starts with our team. We support, challenge, and celebrate one another, and we invest deeply in connection. Why? Because strong relationships drive better outcomes, and because work is more meaningful when we genuinely care about the people we do it with. We care a lot, so our benefits are actually benefits, not just the fun stuff like swag and snacks in the office (though we have lots of those too!). We know the biggest investment we can make is in our employees, so we provide: - A competitive compensation package that includes employee stock options - 401k with 3% company contribution, regardless of whether you contribute (Roth 401k available) - Fully paid healthcare, dental, and vision insurance premiums (family plans included) - Pre-tax FSA and Dependent Care Account - 16 weeks of paid parental leave - Flexible Time Off. Everyone should get out of their office to recharge and reboot. - Annual professional development stipend (courses, conferences, and more) - New hire bonus to enhance your home office setup - Pet insurance discount Wistia provides equal employment opportunities to all employees and applicants for employment and prohibits discrimination and harassment of any type without regard to race, color, religion, age, sex, national origin, disability status, genetics, protected veteran status, sexual orientation, gender identity or expression, or any other characteristic protected by federal, state, or local laws.

Location: Canada What The Role Is As a Staff Engineer at Babylist, you own some of our hardest domains and decide where they go. Millions of families depend on what we build. Agents write most of the code now. So the hard part is yours: what to build, how it should work and whether what shipped was right. You're still in the code for the genuinely hard problems. Agents handle the volume. You spend your time on the parts that need a person. We're building well beyond the registry now: the financial side of raising a kid, maternal health made simpler and more human, the education new parents are looking for and the community around them. The hard problems run across all of it, plus the platform underneath and the AI we already ship to families. You'll own a big piece of the product, but you won't be boxed into it. The roadmap is open. You have a say in which bets we make, and you pick what you take on next. What You'll Own A Staff Engineer here sets direction. You own a domain: a product surface, a platform area or a capability that cuts across several teams. You set where it's going over the next year or two, sequence the bets that get there and make the technical and product calls along the way. You're still in the code. We don't have architects who've stopped building. If you stepped away, multiple teams would feel it. Your influence shows up in the systems and the work other teams choose to build on. You don't need direct reports to have that reach. It comes from what you build. In practice, you: Take a fuzzy business problem from the first sketch through to production, and stay on the hook for whether it actually helped customers. Build the platform or tooling other teams adopt by choice, and own it as it scales. Make the architecture calls that span teams and the ones that are expensive to reverse. Set the standard for how your domain builds with AI. Decide what good looks like, build the patterns and evals that get agents there and catch the output that's confidently wrong before it ships. Partner with product, design and data as a peer, shaping what's worth building from the start. Coach Senior engineers through the hard calls, the ambiguous ones as much as the technical ones. A few problems people at this level are working on right now: Resolving one customer across registry, shop and health, plus the friends and family buying for them, so personalization works everywhere without each team rebuilding it. Designing the knowledge system our coding agents reliably load, and working out how much context actually helps before it starts to hurt. Building Early Investor, our new family finance product, from scratch, on a deadline that can't move. Who You Are You've shipped production systems for enough years to have earned strong opinions, and you hold them loosely. You can pick up an ambiguous problem and start moving before anyone hands you the full picture. You've already changed how a team builds with AI, and the new way stuck. Most Staff engineers lean one of two ways, and both do well here. Some point their depth at the systems everyone runs on: the platforms, the reliability and security bar, the harnesses that make AI produce good code. Others point it at the customer: framing the problem with PMs as peers, owning a journey end to end, deciding what to build and learning whether it worked. You don't have to be both. You do have to be excellent at one and fluent in the other. A few things that tend to be true of people who thrive here: You measure yourself by impact: a customer outcome, or a system a dozen teams come to depend on. You're curious: you spot problems before they're filed and push your own ideas until they ship. Compensation We post real numbers. For a Canada-based Staff Engineer, the starting base salary range is $299,300 to $372,600 CAD, plus a target annual bonus of 20 percent of base. That's total target cash of roughly $359,160 to $447,120 CAD. On top of that you get meaningful equity and an RRSP match. Where you start in that range depends on your experience, and your pay grows from there with performance and scope. How We Build AI is the default here. Engineers run agentic sessions for most of the work, and a lot of the interesting engineering now lives in the scaffolding that makes the agents good: the eval harnesses, the curated context, custom review skills and fast CI. Agents also triage incidents and handle a big share of support. A human always owns the outcome. The architecture is intentionally simple: one Rails monolith, MySQL and few moving parts. That's deliberate. Simple infrastructure lets us move fast and lets AI reason about the whole system, so the hardest problems are the ones in front of customers. The Stack Core app: Rails, Packwerk, React, TypeScript, Sidekiq Mobile: iOS (Swift), Android (Kotlin) Data, search & events: MySQL, Snowflake, dbt, Airflow, Weaviate, WarpStream, Hex, Sigma Machine learning: deep learning, matrix factorization, retrieval & ranking, AWS SageMaker, MLflow AI & dev tooling: Claude Code, Devin, Linear, CodeRabbit, Warden, LangChain, Bedrock AgentCore, Maxim Infra & ops: AWS, Kubernetes, Terraform, GitHub Actions, Datadog, incident.io, LaunchDarkly Key integrations: Shopify (payments), Iterable (CRM) Why Babylist An engineer, expecting her first baby, couldn't find the registry she wanted. So she built it. That's how Babylist started, and it's still how we work: engineers solving problems for families. Becoming a parent is one of the biggest moments in a person's life. Millions reach it for the first time every year, making thousands of decisions and figuring it out as they go. That's who we build for, and we're a long way from done. Ten million people give gifts through Babylist every year. We did more than $750M in revenue in 2025, up 45 percent over the year before, and we've been profitable for eight years while staying independent. So you can take on a hard, multi-year problem without watching over your shoulder for the next round or the next correction. And the team is small, around 65 engineers, so what you ship stays visible and your scope stays wide. How We Work Remote-first across the US and Canada, and we have been for years. That's not changing. We trust you to own your time and your outcomes, and we get everyone in a room together twice a year. Teams are small, pods of three to five engineers, so nothing you ship disappears into a committee. You'll work shoulder to shoulder with product, design and data, and with the partners across the business who rely on what you ship. You'll also stay close to customers yourself: sitting in on user interviews, watching session recordings, riding along with support. Here that's part of the engineering job, on a regular basis. How We Hire Three rounds, usually two to three weeks start to finish. Recruiter conversation (30 minutes). Trade context: what you want next, what we're building and straight answers on comp, team and remote. Technical screen (1 hour). One round, no AI, language-agnostic. Reach for Google when you normally would. We just want to see how you reason from first principles. Final round (4 hours). Four one-hour interviews: system design, AI-assisted coding with the tools you'd actually use here, product sense and culture and values. You'll hear back either way within 24 to 48 hours. If your timeline is tight, tell us and we'll move faster. Benefits Company-paid medical and fully covered dental and vision A RRSP match Generous paid parental leave for birthing and non-birthing parents, plus a gradual return-to-work program Winter Wonder Week, a paid company-wide week off at the end of the year A remote-work stipend Mental-health and wellness support A Few Things To Know We record and transcribe interviews to evaluate candidates, in line with applicable privacy laws. We expect you to use AI in your work and we welcome it in the process, but what you submit and say should reflect your own thinking. If you have a family member or close relationship with a Babylist employee, let your recruiter know. Official outreach only ever comes from an @babylist.com address

Location: Remote US At Affirm, we exist for the moments that matter—giving people a clear, predictable way to pay over time, with no hidden fees, no surprises, and no tradeoffs on what matters most. About the Role Affirm is building its own bank — and this role is one of the most senior individual-contributor seats on the engineering team that runs it. We're looking for a Staff Software Engineer to be a technical anchor for a deliberately small, AI-native team that owns the systems behind Affirm's bank: vendor-integrated banking infrastructure, the data platform, and the operational tooling that holds it all together. You'll set technical direction across that surface area, own the hardest problems on the team — including the Bank ↔ Affirm Inc integration boundary — and operate with direct exposure to senior bank and Affirm leadership. This is a rare opportunity to shape a new business from its very first systems — a startup-like build inside an established company — at a level of ownership that goes beyond delivering your own projects. As a Staff engineer here you set the bar: the architecture, the standards, and the technical strategy that the rest of the team builds against. The team is small and AI-native, the surface area is broad, and the decisions you make carry far — every system you ship serves real customers under a real bank charter, and the patterns you establish determine what the bank becomes. What You'll Do Set technical direction across the bank's systems. Own the medium-to-long-term technical strategy for the bank's core surfaces — cloud infrastructure, data platform, core banking configuration, CI/CD, networking, and the Bank ↔ Affirm Inc integration — and make the architecture calls the rest of the team builds against. Generalist breadth is expected; you go deep where the risk is highest. Own the hardest problems end-to-end. Personally design, build, integrate, and operate the most ambiguous and highest-stakes pieces of the stack, and own incident response for them. You take the problems no one else can fully scope and turn them into well-defined systems with clear failure domains, monitoring, and runbooks. Be the force multiplier on a small team. Set and hold the bar for code review, design review, and examiner-readable documentation. Establish the patterns and standards that let a deliberately small team punch far above its size, and level up every engineer who joins after you. Ship AI-first, and push the frontier of it. Treat AI tools and agentic workflows as a load-bearing capability for code, design review, runbook generation, and operations — and actively push yourself and the team on what an AI-leveraged engineering function can deliver in place of additional headcount. Lead vendor selection and ownership. Drive evaluation, integration, and ongoing oversight of the bank's third-party platforms across the core, data, identity, observability, and card-processing stacks. Carry the bank's most critical vendor relationships end-to-end: integration, operations, escalation, and audit. Define the integration boundary with Affirm Inc. Set the domain edges, data flows, and integration patterns between the bank and Affirm Inc so the bank's products work seamlessly inside the Affirm ecosystem while preserving the legal and regulatory separation the charter requires. Drive this across Affirm Inc engineering teams whose systems integrate with the bank's. Build for examiners. Partner with Legal, Compliance, Risk, BSA/AML, Finance, and Internal Audit so compliance is a property of the product from day one. The systems you design are the artifacts FDIC and state examiners will inspect — design and document them to a standard that holds up under examination and audit review. Own the operational posture of the bank's systems. Set the reliability, observability, alerting, runbook, incident-response, and disaster-recovery practices that keep the bank standalone-operable and audit-ready, while keeping the operational footprint intentionally small. You will support the operations and availability of your team’s artifacts by creating and monitoring metrics, escalating when needed, and supporting “keep the lights on” & on-call efforts. Influence up and across the organization. Communicate technical strategy, tradeoffs, and constraints with clarity to bank executives, the Bank Board, Compliance, Risk — and to engineers outside the bank across the broader Affirm org. The relationships you build beyond the team shape how cleanly the integration boundary works. Help grow the team and the bar. As engineers join, they inherit a function whose architecture, practices, and standards you helped set. Mentor peers, provide high-signal feedback, contribute to hiring, and lead by example. What We Look For 8+ years of software engineering experience, with staff-level, hands-on builder credentials and a track record of owning ambiguous, high-stakes systems end-to-end through launch and operations Comfortable owning ambiguity at the largest scale on the team — you move fast, make the tough prioritization calls, take ownership before being asked, and balance speed with the engineering judgment the hardest decisions require Hungry to leverage AI to drive outcomes — fluent with AI-assisted development tools (Claude, Cursor, Codex, agentic workflows) and actively pushing yourself and your team to use them as a multiplier for code quality, velocity, and what a deliberately small team can ship Bias toward simplicity — experience building toward a small, lean engineering culture that rewards "buy over build", a default-deny posture, and standalone-operability over an abundance of tooling A track record of setting technical direction — you've defined architecture and multi-quarter technical strategy for systems beyond your own projects, and led the execution of it across engineers and teams without needing a management title to do so Deep systems thinking across public cloud infrastructure (AWS preferred), infrastructure-as-code (Terraform), and cloud data platforms (Snowflake or comparable) — you understand their failure modes and tradeoffs, not just their surface APIs Regulated-environment experience — direct work in banking, payments, securities, healthcare, or another setting subject to external examination, where the work involves examiner-facing documentation and decisions Direct experience selecting, integrating, and operating meaningful third-party platforms under operational ownership after launch Comfortable as the technical face of the work to non-engineering stakeholders — bank executives, the Board, Compliance, Risk, Finance, and examiners — and able to document decisions so they hold up under audit review Exceptional written and verbal communication — you can distill complex technical, regulatory, and operational concepts into clear narratives for executives, boards, and non-engineering audiences This position requires either equivalent practical experience or a Bachelor’s degree in a related field Nice to have Prior work inside a bank, neobank, Banking-as-a-Service provider, card issuer/processor, or fintech with a chartered bank subsidiary Direct experience with a de novo bank launch, an early-stage bank buildout, or a greenfield regulated platform Hands-on experience with a bank core, card processing / issuer processor integration, or digital bank experience integration Hands-on experience standing up a greenfield cloud organization — fresh cloud org, IAM model, and data platform — under a tight, default-deny security posture Familiarity with the regulatory framework that shapes the work: FDIC examinations, GLBA / Reg P (affiliate data sharing), BSA/AML, Reg E, Reg DD, Reg Z, model risk, and third-party risk management Compensation & Location Base Pay Grade - P Equity Grade - USA 13 Employees new to Affirm typically come in at the start of the pay range. Affirm focuses on providing a simple and transparent pay structure which is based on a variety of factors, including location, experience and job-related skills. Base pay is part of a total compensation package that may include monthly stipends for health, wellness and tech spending, and benefits (including 100% subsidized medical coverage, dental and vision for you and your dependents). In addition, the employees may be eligible for equity rewards offered by Affirm Holdings, Inc. (parent company).

Location: San Francisco, CA 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. Sierra was co-founded by Bret Taylor https://www.linkedin.com/in/brettaylor/ and Clay Bavor https://www.linkedin.com/in/claybavor/ who first met while working together at Google over 20 years ago. Bret currently serves as Chairman of the Board of Open AI. Previously, he was co-CEO of Salesforce and CTO of Facebook. Clay spent 18 years at Google, where he most recently led Google Labs. ABOUT THE ROLE Sierra is growing fast, and product marketing sits at the center of how we go to market. You'll make sure customers and prospects understand what we build, why it matters to their industry and role, and why Sierra is the right choice. You'll own positioning, messaging, launches, sales enablement, and content, working closely with product, sales, agent development and the rest of marketing. WHAT YOU'LL DO - Shape how we tell our story. You’re a passionate product marketer, energized by messaging and positioning and skilled at building a message for a feature, product, industry or buyer. One day you may update web copy, the next you build an event session, craft a sales narrative, write a launch blog post, or create content for a campaign. - Lead product launches. When a product or new feature ships, you lead how we go to market - the messaging, the assets, and the sales enablement. Sometimes this means translating to industries or buyers. - Arm our sales team. You build and maintain the playbooks and assets our GTM teams use to sell including slide decks, landing pages, demos and more. - Build with AI-first. You’re AI fluent, and your first instinct is to self-serve and improve how you work. You’ll help build the automations, templates, and systems that keep our work consistent across industries and workstreams. - Go wide and deep. You flex across channels and activations, and you can go deep on one area, such as an industry vertical, a persona, or our web strategy. You’re comfortable with ambiguity and a fast pace, and you like to build. WHAT YOU'LL BRING - 4+ years of B2B or B2C product marketing experience. - Expertise in positioning and messaging, leading product or feature launches, and building sales-facing and customer-facing assets for different audiences and industries. - Strong operational instincts. You think in process, systems, and repeatable frameworks, and you’re comfortable building structure where none exists. - Fluency with tools like ChatGPT or Claude to work faster and automate where it makes sense. - A passion for storytelling and experience building presentations in Google Slides. - Comfort being on a lean team that’s still being defined, and enthusiasm for shaping how it works. SAMPLE PROJECTS - Take a new product from roadmap to launch: positioning, messaging, sales assets, enablement, and demo. - Go deep on an industry and understand how our product can help that segment, build messaging that resonates, and downstream assets. OUR VALUES - Trust: We build trust with our customers with our accountability, empathy, quality, and responsiveness. We build trust in AI by making it more accessible, safe, and useful. We build trust with each other by showing up for each other professionally and personally, creating an environment that enables all of us to do our best work. - Customer Obsession: We deeply understand our customers’ business goals and relentlessly focus on driving outcomes, not just technical milestones. Everyone at the company knows and spends time with our customers. When our customer is having an issue, we drop everything and fix it. - Craftsmanship: We get the details right, from the words on the page to the system architecture. We have good taste. When we notice something isn’t right, we take the time to fix it. We are proud of the products we produce. We continuously self-reflect to continuously self-improve. - Intensity: We know we don’t have the luxury of patience. We play to win. We care about our product being the best, and when it isn’t, we fix it. When we fail, we talk about it openly and without blame so we succeed the next time. - Family: We know that balance and intensity are compatible, and we model it in our actions and processes. We are the best technology company for parents. We support and respect each other and celebrate each other’s personal and professional achievements. WHAT WE OFFER We want our benefits to reflect our values and offer the following to full-time employees: - Flexible (unlimited) paid time off - Medical, dental, and vision benefits for you and your family - Life insurance and disability benefits - Retirement plan dependent on country of employment - Parental leave - Fertility and family building benefits - Lunch, as well as delicious snacks and coffee to keep you energized when working onsite - Discretionary benefit stipend giving people the ability to spend where it matters most - Free alphorn lessons These benefits are further detailed in Sierra's policies, may vary by region and employment type, and are subject to change at any time, consistent with the terms of any applicable compensation or benefits plans. Eligible full-time employees can participate in Sierra's equity plans subject to the terms of the applicable plans and policies. BE YOU, WITH US We're working to bring the transformative power of AI to every organization in the world. To do so, it is important to us that the diversity of our employees represents the diversity of our customers. We believe that our work and culture are better when we encourage, support, and respect different skills and experiences represented within our team.
