About Stainless

Stainless is a fast-growing tech startup building the future of APIs. Our customers include industry leaders like OpenAI, Anthropic, and Cloudflare.

We are headquartered in NYC, just west of SoHo, and expect to grow from ~20 to ~40 people in 2025.

Role

You’ll lead product development for our SDK generator, a “compiler” from OpenAPI specs to idiomatic wrapper libraries in various languages for customers including OpenAI, Anthropic, and Cloudflare.

Responsibilities

Day-to-day you will:

Support engineers in shipping new SDK generator features quickly and achieving high level of technical quality.

Oversee development of new SDK generators for e.g., C#, PHP, Rust, Swift, Elixir, etc.
Drive our core “compiler” design to support many programming languages, library features, and edge cases.
Scale our SDK build platform to manage hundreds of concurrent customer builds.
Partner with OpenAI, Anthropic, et al on the design of future APIs and their optimal support in SDKs.
Act as editor-in-chief of our technical documentation.
Mentor high-slope engineers toward rapid career growth.
Source, interview, and close some of the best engineers you’ve ever worked with.

You’ve personally recruited engineers to join a team you manage.
You’ve worked on libraries, for example building a popular open source project or designing internal abstractions used across a company.
You’re interested in growing your management skills as the team scales over the next 2 years.
