About Fern, a Postman Company

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 New York City.

About the Role

As a Software Engineer at Fern, you’ll build APIs, scale AI infrastructure, and design developer experiences that reach millions of people. Scale infrastructure to keep up with growth: Work on AI systems deployed on Vercel, AWS, and Turbopuffer that must be performant, reliable, and secure under real-world load. Stay close to customers: We work directly with API teams at companies like Nvidia, Twilio, and Square. You’ll debug real production edge cases, shape APIs based on customer feedback, and ship improvements quickly. Collaborate across the stack: Partner closely with product designers and frontend engineers working in TypeScript and Next.js to define polished interfaces and slick user experiences.

What We’re Looking For

You have 2+ 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.

What Else?

The reasonably estimated base salary for this role ranges from $160,000.00 to $190,000 plus a competitive equity package. Actual compensation is based on the candidate's skills, qualifications, and experience.
