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.
Manage customer relationships: whether they’re an Engineering Manager, Director of Developer Experience, or Software Engineer, you’ll be the face of Fern during the technical evaluation of our product. You’ll develop a strong network within the SaaS startup community, especially among YC founders.
Own onboarding from start-to-finish: once a company decides to purchase Fern, you’ll lead the onboarding process to ensure they go live successfully. This includes project management (milestones, responsibilities, status updates) and writing code within our customers’ code repositories.
Educate our users: when customers have questions about the product, you’ll guide them to our docs, tutorials, and examples. If you identify a gap in our documentation, you’ll take ownership by writing the missing content and helping drive product roadmap.
