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

We have raised over $35 million from a16z, Sequoia, and founders/C-levels from Stripe, Datadog, Segment, Linear, and more.

We are headquartered in NYC, just west of SoHo, and are a team of ~60 strong expecting to double in the next ~9 to 12 months.

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.

You’ll be one of 2 engineering leaders overseeing Stainless Engineering and will manage 6-12 engineers. This role reports to the CEO and is onsite at our office in Manhattan.

• 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.

• You’ve personally recruited engineers to join a team you manage.

• You have 2+ years of engineering management experience and have managed more than one team.

• 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.

• You’ve started something before: a business, a club, a nonprofit, a student org; anything that shows you’re a builder at heart.

• We offer competitive salary and generous equity grants.

• Great healthcare coverage options (e.g., fully covered platinum plans).

• Paid commuter benefits & similar.
