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, ~50 people, with strong revenue, several years of runway, and backing from Sequoia and a16z.

As one of our first 35 engineers, you’ll have real ownership, autonomy to build great products, and a direct hand in shaping the future of how developers consume APIs.

Boundary (YC W23) | Software engineer (compilers) | Seattle, USA (in person) | Full-time

We are building a new programming language (BAML) to build AI agents -- the "typescript" for LLMs. We are open source: https://github.com/boundaryml/baml

We are looking for engineers with experience with Rust, programming languages, and/or compilers. Any amount of experience is fine.
