Staff Software Engineer
Fern
About Fern
Fern helps software companies build a world-class API experience. Our customers include industry leaders like Nvidia, Square, and Twilio, as well as fast-growing AI companies like ElevenLabs and OpenRouter.
In the next year, the majority of API integrations will be implemented by AI agents. Agents don’t read marketing pages. They need strongly typed schemas, structured endpoints, deterministic contracts, and documentation that can be fed into a context window.
Our team is small and talent-dense. We’re a team of builders from Google, Palantir, Amazon, and Uber, working together in Williamsburg, Brooklyn. We were acquired by Postman — giving us access to 40 million users and 98% of the Fortune 500 — while maintaining the independence, speed, and ownership of a startup.
About the Role
As a Staff Software Engineer at Fern, you’ll build APIs, scale AI infrastructure, and design developer experiences that reach millions of people.
Set technical direction: Drive system design decisions around data modeling, performance, correctness, and reliability. Identify scaling bottlenecks before they become problems.
Build for durability and scale: Ensure our systems are performant, observable, secure, and resilient under real-world production load across infrastructure (e.g., Vercel, AWS, Turbopuffer). Read about how we use Vercel and Next.js to achieve efficient multi-tenancy and faster development cycles.
Mentor motivated engineers: Developing people is as important as developing software. From in-depth code reviews to high-level architectural discussions, you'll help elevate the skills and impact of those around you.
Collaborate across the stack: Partner closely with product designers, backend, and frontend engineers working in TypeScript and Next.js to define polished interfaces and slick user experiences.
What We’re Looking For
You have 8+ years of professional software engineering experience.
We’re building open source and we care deeply about taste — we’re looking for builders that know developer experience is a craft.
Strong written and verbal communication skills to solve technical problems with customers.
Bonus: Experience building with TypeScript.
