Generalist / SDK software engineer

Stainless is a rapidly growing startup revolutionizing the API development landscape, backed by Sequoia and serving industry leaders like OpenAI, Anthropic, and Cloudflare. Founded in 2022, we're expanding our NYC-based team from 15-20 to approximately 70 people over the next three years.

As a Generalist/SDK Software Engineer, you'll be at the forefront of building our core systems, working directly with our CEO to develop an industry-leading open-source TypeScript API Framework. Our mission is to combine the best aspects of GraphQL and gRPC with REST's simplicity and widespread adoption.

The role offers a unique blend of technical challenges and creative freedom. You'll be instrumental in developing our API client libraries service, where customers can simply send their OpenAPI spec and we generate professional-grade client libraries in multiple languages. This position requires both technical expertise and the ability to think strategically about developer experiences.

Key technical aspects include working with TypeScript, Node.js, and various programming languages, building rich tooling with static analysis and potentially LLMs, and engaging with the open-source community. You'll also contribute to documentation, website development, and direct customer engagement to understand developer needs.

We offer competitive compensation ($150K-$220K based on level), generous equity grants, and comprehensive benefits including healthcare, commuter benefits, and flexible PTO. The position is hybrid, requiring 3+ days in our Manhattan office, fostering a collaborative environment while maintaining flexibility.

This is an exceptional opportunity for a polyglot developer who's passionate about developer experience, has experience with API design and implementation, and wants to make a significant impact in the developer tools space. Join us in building the future of API development!
