Full Job Description
About the role As a Staff Engineer, you'll own a large surface area of the product, both by being a product and system architect that's helpful to others on the team, as well as being a core individual contributor. You'll have significant ownership over how thousands of developers build AI agents, from API design to SDK ergonomics to the abstractions that make agentic systems easy to build.
This is a high-leverage role where you'll:
Own platform features end-to-end: architect, build, and maintain critical systems that our customers depend on.
Lead technical and team direction: Serve as a leader and resource
Shape the developer experience: design APIs, SDKs, and tools that developers love to use
Build at the frontier and in public: work on cutting-edge agentic systems and see your work used in production at leading AI companies -- all while contributing to open source.
Influence product direction: your technical and product insights will directly shape our roadmap
Work directly with customers: understand how teams build AI agents and design elegant solutions for their needs
What we're looking for
Strong TypeScript expertise: 4+ years building full-stack products with TypeScript, with a deep understanding of end-to-end web fundamentals
System design skills: you can architect APIs and systems that are elegant, scalable, and developer-friendly
Product thinking: you care about the end-user experience and think through how people will actually use what you build
Full-stack fluency: comfortable working across the stack, from APIs to SDKs to UIs
High ownership: you want to own problems end-to-end, not just ship code
Bonus points for
Experience building with AI (prompts, evals, RAG, agentic workflows, etc.)
Background in developer tools or B2B SaaS products
Open source contributions or public projects that demonstrate your craft
UX or design sensibility
Our craft-driven culture We expect every engineer to have strong product intuition and to think through the complete user experience. If you love building for other developers and are excited about building end-to-end agentic systems, this role is a great fit.
Why join us
High impact: shape the platform that powers AI agents for leading companies
Technical depth: work on complex, challenging problems at the frontier of AI
Ownership: drive product, architectural, and technical decisions end-to-end
Learning: get deep on how AI Agents work and what it takes to ship them in production
