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 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 expect to grow from ~20 to ~40 people in 2025.
Role
Applied AI Engineers build and deepen the technical relationship between Stainless and our most important users. The role is technically engineering, but functionally, it’s much more dynamic. You’ll be working closely with some of the top AI labs in the world (OpenAI, Anthropic, etc) helping them architect, launch, and scale their APIs with Stainless. It’s part engineering, part product, part deployment with lots of ambiguous, high-impact problems to solve alongside the folks shaping the future of AI.
To thrive in this role, you’ll need strong judgment, broad technical fluency in multiple programming languages, and the ability to navigate unfamiliar codebases with confidence. You’ll move fast, learn even faster, and directly shape the experience of some of the most influential developers on the planet.
What You'll Do

• Work directly with critical customers like OpenAI, Anthropic and Cloudflare to:
• Evolve their SDKs through the release of new features.
• Directly contribute to their SDKs by writing custom helpers, utilities and extensions for advanced use cases like structured outputs and tool-calling. You’ll work closely with companies like OpenAI and Anthropic as a critical partner.
• Do all of this across all languages that Stainless supports, learning new languages where needed.
• Build AI-powered tooling to:
• Configure new users’ SDKs when signing up for Stainless.
• Translate custom tailored solutions from one language to many.
• Write rich, purpose-built examples and demos for prospective customers.
• Write great docs, help build a great website, do what needs done.
• Write code both internally and for external customers. Some examples:
• Improving our SDK Codegen to handle new use-cases.
• Writing examples and demos for new feature releases.
  

Who you are

• You have broad polyglot interest/experience – comfort working across multiple programming languages, and enthusiasm to build proficiency with even more.
• You have experience using AI to generate high-quality code.
• You have a true passion for developer experience and empathy for developers from all backgrounds (junior, non-traditional, expert power-user etc).
• You love connecting with all users: learning their needs and coming up with creative solutions to solve them.
• You care deeply about great communication about technical subjects, from terseness of a tweet to an expanded tutorial in documentation.
• You’re a quick learner, self-motivated, and able to execute quickly whilst maintaining high quality.
• You love crafting a great product. You appreciate and show extreme detail-orientation in articulating papercuts and finding every possible corner of polish.
• You have experience building and consuming APIs.
• You've built and/or maintained a popular open-source project.
• You’ve started something before: a business, a club, a nonprofit, a student org; anything that shows you’re a builder at heart.
