About The Job

We need someone who is equally comfortable writing C and JavaScript. The Bare team builds and maintains the runtime itself along with a growing ecosystem of native modules (bare-bluetooth, bare-tcp, bare-fs, bare-crypto, and many more). You would be writing native addons that bridge platform APIs into JavaScript, debugging across multiple operating systems, and helping keep the runtime small and correct.

This is a hands-on systems role. You will work independently, own modules end to end, and ship code that runs on phones, laptops, servers, and constrained devices.

Native module development

• Design, implement, and ship bare-* native modules (e.g., bare-bluetooth, bare-tcp, bare-fs, bare-crypto) end to end, including code, and tests
