Software Engineer, Python SDK

This role is ideal for ambitious Python engineers with entrepreneurial goals. We are looking for a Python expert to lead the development of Fern's Python SDK generator. Your work will directly influence the experience of thousands of developers using SDKs for companies like Square, ElevenLabs, Cohere, Webflow, and more. You'll define what high quality looks like in Python SDKs and help set the standard for the broader Python community. Many of us are former or future founders, and this is an opportunity to scale a company from $1M to $10M ARR while partnering with fast-growing tech companies shaping the future of software. We value in-person collaboration and work out of our office in the Williamsburg neighborhood of Brooklyn. What you'll do: Define Python best practices. You'll set the tone for how a modern Python SDK should feel — readable, idiomatic, and a joy to use. We're constantly raising the bar to make our SDKs the best in the industry. This is more than code generation; it's about crafting Python libraries that developers trust and love. Build out our compiler. You'll own core components of our open source compiler, defining the primitives that power every one of our SDKs. You'll implement new capabilities like auto-pagination and server-sent events, and push the boundaries of what a generated SDK can offer. Engage with the Python community. You'll stay on top of modern Python tools and frameworks, incorporate best practices, and work directly with developers through GitHub issues and community forums to evolve the SDK based on real-world needs. Build our team. You'll work closely with our CEO and CTO to recruit and mentor new engineers as we scale.
