Staff Software Engineer - Fern

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.

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.
