Ask HN: Who is hiring? (August 2025)

When you npm install openai or pip install anthropic, you’re pulling code generated by Stainless.

We’re building the platform for high-quality, easy-to-use APIs — and companies like OpenAI, Anthropic, and Cloudflare already rely on us.

We’re ~3 years old, ~35 people, with strong revenue, several years of runway, and backing from Sequoia and a16z.

As one of our first 25 engineers, you’ll have real ownership, autonomy to build great products, and a direct hand in shaping the future of how developers consume APIs. We’re looking for exceptionally productive, thoughtful, and kind people who want to make software development better for everyone.

What Stripe did for payments, Pylon is doing for the mortgage industry: We're taking a sleepy industry with backward technology and re-building the stack from the ground up. We're first-principles thinkers, and our team is small, talented and ambitious.

I'm hiring generalists who love coding and want to build something beautiful in an industry where technology written in the 90s is the norm. We're Series A, well funded, and we have traction with customers. Come to Menlo Park or SF and help us turn the $2 trillion US mortgage industry into a set of APIs.
