Requirements
  • You've managed technical programs and are comfortable getting into the details of a technical product.
  • You've helped technical stakeholders understand project timelines, trade-offs, and confidently navigate the complexity of multi-language SDK rollouts in a fast-evolving space.
  • You have 2-4 years of program management experience.
  • You've started something before: a process, a team initiative, a side project; anything that shows you're a builder at heart.
  • You're naturally curious and intrinsically motivated. You like figuring things out, and you like helping others do the same. You learn fast and move fast.
  • You take feedback well, act on it quickly, and want to be part of building something from the ground up. We are a high confidence, low ego team.
  • You've got strong communication skills: clear writing, calm presence on calls, and an ability to explain complex things simply.
  • You have experience managing projects with multiple stakeholders and technical dependencies.
Responsibilities
  • Own end-to-end delivery of enterprise SDK projects, from initial scoping to post-launch success, with support from engineering and customer success teams.
  • Help enterprise customers adopt Stainless by guiding them through requirements gathering, custom configuration needs, and coordinating any engineering work needed for their SDK launches.
  • Maintain clear project visibility, track dependencies accurately, and help us keep a sharp eye on what's working and what's not.
  • Provide tight feedback to engineering leadership on what customers are bumping into, what custom work is needed, and what patterns are emerging.
  • Identify and execute opportunities to improve our delivery processes, project templates, customer communications, and operations. And be a strong partner to these teams to put ideas into action.
Desired Qualifications
  • Bonus if you've worked in devtools or API-first companies.
  • Comfortable managing multiple projects in parallel, even better if you've already built your own project tracking systems.
  • Technical background or familiarity with APIs and SDKs (not required, but it helps).

StainlessAPI develops tools that help software engineers generate language-idiomatic SDKs from REST APIs. It takes an OpenAPI Specification and automatically produces client libraries tailored to specific programming languages, so developers can use APIs without writing or maintaining multiple language clients. The product works by parsing the API definition and emitting SDKs that follow each language's conventions, enabling fast, consistent integration with APIs. StainlessAPI differentiates itself by focusing on automated SDK generation from OpenAPI, reducing manual boilerplate and ensuring consistency across languages, rather than competing primarily on features like hosting or analytics. Its goal is to speed up API development and maintenance for developers and tech teams, typically via a subscription-based model that scales with enterprise needs.

Stainless is helping OpenAI, Anthropic and others build SDKs for their APIs

Rattray, who studied economics at the University of Pennsylvania, has been building things for as long as he can remember, from an underground newspaper in high school to a bike-share program in college. Rattray picked up programming on the side while at UPenn, which led to a job at Stripe as an engineer on the developer platform team. At Stripe, Rattray helped to revamp API documentation and launch the system that powers Stripe's API client SDK.

Stainless Is Helping Openai, Anthropic And Others Build Sdks For Their Apis

Besides a focus on generative AI, what do AI startups like OpenAI, Anthropic and Together AI share in common? They use Stainless, a platform created by ex-Stripe staffer Alex Rattray, to generate SDKs for their APIs.Rattray, who studied economics at the University of Pennsylvania, has been building things for as long as he can remember, from an underground newspaper in high school to a bike share program in college. Rattray picked up programming on the side while at UPenn, which led to a job at Stripe as an engineer on the developer platform team.At Stripe, Rattray helped to revamp API documentation and launch the system that powers Stripe’s API client SDK. It’s while working on those projects Rattray observed there wasn’t an easy way for companies, including Stripe, to build SDKs for their APIs at scale.“Handwriting the SDKs couldn’t scale,” he told TechCrunch. “Today, every API designer has to settle a million and one ‘bikeshed’ questions all over again, and painstakingly enforce consistency around these decisions across their API.”Now, you might be wondering, why would a company need an SDK if it offers an API? APIs are simply protocols, enabling software components to communicate with each other and transfer data. SDKs, on the other hand, offer a set of software-crafting tools that plug into APIs. Without an SDK to accompany an API, API users are forced to read API docs and build everything themselves, which isn’t the best experience.Rattray’s solution is Stainless, which takes in an API spec and generates SDKs in a range of programming languages including Python, TypeScript, Kotlin, Go and Java
