Backend Engineer

**This role is in person at our office in the Williamsburg neighborhood of Brooklyn, NY.**

As a small team, we're all generalists, constantly pick up new challenges, and interface with customers regularly. Regarding product and code, we're looking to work with experienced people who can pick a problem and solve it.

We're adding new customers every week, and as a result, we have more questions, feedback, and support tickets from developers using Fern than ever before. That's why we're adding a customer-centric software engineer to our team.

### **What you'll do**

* **Have direct relationships with customers.** Whether they're a CTO, VP of Eng, or Software Engineer, you'll be the face of Fern and the first person they turn to when they need help. You'll quickly build a network within the SaaS startup community, especially among YC founders.
* **Move fast.** To support our customers, you'll work across several codebases to release bug fixes and features. For example, one day you may fix a bug related to our TypeScript SDK generator and another day you may add features to the Docs Frontend.
* **Drive our product roadmap.** When you hear a request from a customer that feels _hard to build_, they may be questioning an assumption we made 6 months ago or proposing a feature requiring a large engineering effort from us. You can use this customer context to build something people want.™
* **Build our team.** We're growing, and you will work directly with the CEO, CTO, and other founding members to bring in talented engineers.

### **What you'll bring**

* 4+ years of professional software development, ideally some of which you've spent as a solutions engineer, forward deployed engineer, or founder
* Strong written and verbal communication skills
* Significant experience working with the OpenAPI specification
* Significant experience with TypeScript
* Ability to think on your feet and solve problems during calls with technical customers
* Willingness to be a polyglot and work across multiple programming languages (e.g., TypeScript, Python, Rust)

### **What we offer**

* Interesting and challenging work
* An opportunity to build a network of founders and engineering leaders 
* First-hand experience building an early-stage startup
* A salary of $156,000 to $192,000 and equity
* Living proximity bonus of $18,000 per year if you choose to live near the office
* Meals (breakfast, lunch, and dinner) at the office
* Health, dental, and vision insurance
* Unlimited vacation

### **Our tech stack**

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

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.

**Fern enables businesses to offer "Stripe-level" SDKs (client libraries) and Docs for their REST API.** Inspired by internal tooling we saw at AWS and Palantir, we're building Fern to let every engineering team offer easy-to-use and well-documented APIs.

Founded in 2022, we're less than 10 people, building open source, and backed by YCombinator. We work together in our office in the Williamsburg neighborhood of Brooklyn, NY. Our customers include Cohere, ElevenLabs, Webflow, and Merge.dev.
