Software Engineer, Frontend

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. 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 Frontend Engineer at Fern, you'll own and build core user-facing features for our developer platform—from intuitive in-browser tooling to infrastructure that powers thousands of docs sites. This role combines product thinking, system design, and customer empathy to ship fast and high-quality software.

• Build user-facing features such as a WYSIWYG editor to replace Markdown files with an intuitive in-browser app or a changelog to track developer documentation changes over time. You’ll oversee the architecture, design, deployment, and customer adoption of these features.

• Manage our frontend infrastructure by leading the implementation of Storybook, enhancing our CI/CD pipeline, optimizing web application performance, and implementing application monitoring to ensure robust and reliable operations.

• Streamline the developer experience for our monorepo by sharing and implementing your vision of an ideal internal developer experience. You will reduce build times, accelerate deploy times, and increase time-to-ship for our customers!

• Be a power-user of Vercel. We host a multi-tenant Next.js app that powers hundreds of documentation websites. Check us out on Vercel's blog. We're enterprise customers of Vercel and have an active Slack channel with their team. You'll be an owner of the frontend, which is open source!

• Earn trust with customers. Work with developers from startups, growth-stage companies, and enterprises. Collaborate to understand their needs and define product requirements.

• 3+ years of software development

• Strong communicator; comfortable solving technical problems with customers

• TypeScript proficient with willingness to work across multiple languages

• Experience with OpenAPI, AsyncAPI, Protobuf, Conjure (Palantir), Smithy (AWS), Coral (Amazon)

• Your personal GitHub profile is a deep green from commits and side projects

• Prime office location in the heart of Williamsburg, Brooklyn

• Bonus $18,000 per year for living close to the office

• Free meals (breakfast, lunch, and dinner)

• Health, dental, and vision insurance

• Unlimited vacation

• Flexible WFH policy

• Domestic and international team offsites
