Software Engineer, Backend

About Fern:

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, Eleven Labs, 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. Fern is growing more than 5x year-over-year, is at the Series A stage, and has raised over $10M from Bessemer and Y Combinator.

• 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 Backend Engineer at Fern, you’ll own the infrastructure behind our multi‑tenant Next.js app that powers hundreds of documentation sites. You’ll drive zero‑to‑one product features end to end. Our stack includes AWS, Type Script, and modern tooling optimized for developer experience. You'll work closely with the CEO and CTO to grow the team and build the systems that make our platform fast, scalable, and developer‑first.
