Software Engineer, Generalist

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 40 strong expecting to double in the next ~6 to 9 months.

Joining as a generalist engineer, you’ll have a focus area, but we’ll all be pitching in on every aspect of the company and acting with a high degree of ownership in a collegial, humble atmosphere.

You'll build the core systems that form the foundation of the company for years, both scrappily getting things done wherever help is needed and thinking deeply on foundational architecture.

• Experience level to build anything you can imagine, with great design and sound architecture.

• Built and/or maintained a popular open-source project.

  • Alternatively, maintained internal abstractions used across an engineering org.

• Experience consuming APIs you didn’t control, produced APIs you didn’t consume, and been the sole consumer of an API you built and could iterate on.

• Location: onsite in our physical office location in Manhattan, New York.

• Experience both designing and stewarding APIs at scale, whether internal or external.

• Ability to build great abstractions that stand the test of time when used by other engineers of varying skill levels, beginner to formidable.

• A true passion for developer experience and empathy for developers from all backgrounds (junior, non-traditional etc).

• Quick learner, self-motivated, and able to execute quickly whilst maintaining high quality.

• Great product sense.

• Programming languages:

  • Expertise with TypeScript, our language of choice.

  • Broad polyglot interest/experience – comfort working across multiple programming languages.

• Bonus points:

  • Have used GraphQL and appreciate its benefits and drawbacks.

  • Experience / interest working with ASTs (eg, lint rules, rich codemods, compilers, etc).

  • Experience and/or interest in writing blogs, speaking at conferences and engaging with developer communities.

• We offer competitive salary and generous equity grants.

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

• Paid commuter benefits & similar.

• Paid team lunch/meals during workdays.

• Flexible PTO plus 3 weeks of company-wide vacation a year (2 weeks in December, 1 week at the end of the summer).

• Flexible WFH and 1 month fully remote per year ("remote February").
