About The Position

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 cloud infrastructure (e.g., Vercel, AWS). 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 and frontend engineers working in TypeScript and Next.js to define polished interfaces and slick user experiences.
