Fern helps software companies build a world-class API experience. Our customers include industry leaders like Nvidia, Square, and Twilio, as well as fast-growing AI companies like ElevenLabs and OpenRouter.
In the next year, the majority of API integrations will be implemented by AI agents. Agents don’t read marketing pages. They need strongly typed schemas, structured endpoints, deterministic contracts, and documentation that can be fed into a context window.
Our team is small and talent-dense. We’re a team of builders from Google, Palantir, Amazon, and Uber, working together in Williamsburg, Brooklyn. We were acquired by Postman — giving us access to 40 million users and 98% of the Fortune 500 — while maintaining the independence, speed, and ownership of a startup.
About the RoleAs a Sales Engineer at Fern, you’ll work side-by-side with companies who care about their developer experience. You’ll help them understand what’s possible with Fern, answer the tough technical questions they can't get out of our AI assistant, and partner with Account Executives to build trust with prospective customers.
This is a hands-on keyboard role at the intersection of engineering and customer success.
Be a trusted partner in complex deals. Many of the companies we work with have multiple stakeholders — engineering leaders, platform teams, product, sometimes even the CEO. You’ll help guide thoughtful, often months-long sales cycles by understanding their real requirements and making sure nothing gets lost in translation.
Know the product deeply. Our customers will look to you as a product specialist. Fern covers SDKs, API docs, and CI workflows. You’ll understand how it all works and how it fits into a customer’s stack.
Run thoughtful, tailored demos. You won’t give the same demo twice. You’ll shape each one around the customer’s use case, adapt in the moment, and follow up with questions that you can't answer on the spot.
Work closely with AEs. You’ll team up with our Account Executives to move deals forward. You’ll know when to jump in, when to push deeper technically, and how to divide the work to keep momentum.
