Software Engineer

About Us

REST APIs underpin the internet, but they 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.

We're a tiny team building a product that aims to be used by every software team in the world. We're passionate about building something people want ™️. Ambitious work is fun, join us…

Today, companies use Fern to automatically generate:

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

The Role

Fern is open source, check out our repo here. At Fern, you’ll wear multiple hats: making architecture decisions, diving into language design, and supporting our customers in Slack. Engineering is divided across two products (1) SDKs and (2) Documentation, and you’ll have an opportunity to work on both!

You will

• Have complete ownership 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.
• Dive into whatever language we need to work with; our SDK generators are written in the language they generate, and we have four: TypeScript, Python, Java, and Go. If you’re a polyglot or interested in learning multiple languages, this is the place for you!
• Work directly with the CEO, CTO, and other founding members and help build out our team.

Our tech stack

• NextJS + Vercel (Frontend)
• Fern (API)
• Microservices: Express (NodeJs), FastAPI (Python)
• Postgres DB + Prisma ORM
