At Fern, we believe every software company should offer a world-class API. We're building the toolkit to make that possible. We enable customers like Square, ElevenLabs, Webflow, and Intercom to offer a best-in-class developer (DX) and agent experiences (AX).
Our team is primarily ex-Palantir and ex-founders, working together from our office in Williamsburg, Brooklyn. We give builders the autonomy to take ownership, the speed to move quickly, and the support to do the best work of their careers.
Why you should work here:Experience a hyper-growth startup: Join a top-decile growth company early. You'll get firsthand exposure to how a startup scales with visibility into product, engineering, design, and go-to-market. Thinking of founding a startup someday? This is the place to learn.
High trust and autonomy: You’ll have ownership over meaningful projects from day one, with the freedom to shape technical decisions and influence product direction. We trust engineers to figure out the best path forward—without micromanagement.
We move quick: Your code will ship quickly and be used by our customers within days (and sometimes hours). We prioritize shipping fast, and invest in the developer experience toolchain to make that possible.
Few meetings and bureaucracy: No bloated sprint rituals or unnecessary status updates. Just clear priorities, thoughtful async communication, and space to build.
Palantir-inspired customer obsession: Many of our engineers come from Palantir and bring the same focus on solving real customer problems. You’ll work directly with users to tackle their top developer priorities and shape the product through hands-on feedback.
As a Frontend Deployed Engineer, you’ll work directly with our customers to solve their highest-priority problems. You’ll go deep on their use cases, build relevant products / features, and influence our product roadmap. This is a hands-on, high-impact role at the intersection of engineering and customer success.
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.
