Senior Software Engineer - Fern at Postman, New York

Senior Software Engineer - Fern at Postman in New York, NY By 2026, the majority of API integrations will be implemented by AI agents rather than human developers reading marketing pages. These agents require strongly typed schemas, structured endpoints, deterministic contracts, and documentation designed to fit within a context window. Fern — a Postman company whose customers include Nvidia, Square, Twilio, ElevenLabs, and OpenRouter — is building the tooling to make that possible. Postman itself serves over 45 million developers and 98% of the Fortune 500, making this one of the few roles where infrastructure work directly shapes how millions of people interact with APIs in an AI-first landscape. About the Role This full-time position is based in New York City, where Fern's talent-dense team operates. The group is composed of builders from Google, Palantir, Amazon, and Uber, and collaborates in person five days a week. As a Senior Software Engineer, you will build APIs, scale AI infrastructure, and design developer experiences that reach a broad audience. What You Will Do Scale AI infrastructure: Work on systems deployed across Vercel, AWS, and Turbopuffer that must remain performant, reliable, and secure under real-world load. Stay close to customers: Debug genuine production edge cases alongside API teams at enterprises like Nvidia, Twilio, and Square. Shape endpoints based on direct feedback and ship improvements rapidly. Collaborate across the stack: Partner with product designers and frontend engineers working in TypeScript and Next.js to craft polished interfaces and seamless user experiences. What We Are Looking For 5+ years of professional software engineering experience. A deep appreciation for developer experience as a craft — the team builds open source tools and cares profoundly about taste and quality. Strong written and verbal communication skills to solve technical problems collaboratively with customers. Bonus: experience building with TypeScript. Compensation and Benefits The reasonably estimated base salary ranges from $200,000 to $250,000, plus a competitive equity package. Actual compensation depends on skills, qualifications, and experience. Postman also provides comprehensive benefits including full medical coverage, flexible PTO, wellness reimbursement, a monthly lunch stipend, donation-matching programs, and frequent team-building events. The company fosters an inclusive culture where everyone can be the best version of themselves. Applications are open through November 30, 2026. Postman is an Equal Employment Opportunity and affirmative Action Employer. #J-18808-Ljbffr Neolife Updates
