About Us

REST APIs underpin the internet but are still painful to work with. They are often untyped, unstandardized, and out-of-sync across multiple sources of truth.

With Fern, we aim to bring great developer experiences to REST APIs. At AWS and Palantir, we saw first-hand how code generation tooling allows developers to build faster without worrying about the pitfalls of API development. We’re building Fern open source to bring that tooling to every software company.

Today, companies use Fern to automatically generate:

• SDKs: Flatfile, merge.dev, and Vellum
• API Documentation: Vellum, SuperAgent, and Mercoa

We're growing fast and are excited for new teammates to join us. We're passionate about building something people want ™️.

The Role

Fern is open source, check out our repo here. At Fern, you’ll wear multiple hats: making architecture decisions, diving into UI design, and supporting our customers in Slack.

Engineering is divided across two products (1) SDKs and (2) Documentation. This role is focused on the Documentation product.

You will:

• Have complete agency over the work you do — as a member of an early-stage startup, you’ll have the opportunity to own large areas of product and engineering and have direct relationships with customers.
• Being heavily involved in key technology decisions and features, building for performance at scale.
• Work closely with the CEE, CTO, and Designer to bring elegant and intuitive experiences to life.

Our tech stack:

• Next.js + Vercel (Frontend)
• Fern (API)
• Microservices: Express (Node.js), FastAPI (Python)
• Postgres DB + Prisma ORM (Backend)
• AWS CDK (Cloud)
