Chalk is the AI data platform that delivers real-time context and compute infrastructure for agents and ML models — deployed in your cloud, built for speed. Backed by General Catalyst and Felicis.
About the role
We are hiring a Software Engineer to make every other engineer at Chalk move faster. You will be responsible for building our internal developer platform, from Bazel and CI through to release automation, and the tooling engineers use locally. Today this work is spread across the engineering team alongside everything else people are shipping. You would be the first person to own it outright, set the priorities, and build the function from here.
What they're looking for
- 5+ years of professional experience as a Software Engineer, ideally in developer productivity
- C++ coding experience as a Software Engineer
- Strong Distributed Systems experience
- Ideally have hands-on Bazel experience. You have written and debugged BUILD files and Starlark, configured toolchains, and worked through either a real migration or in a large existing workspace
- Ability to work autonomously and to make pragmatic tradeoffs with an eye towards business outcomes
- Strong communication skills

About Chalk
Chalk is building the data platform that powers the future of machine learning applications. We tear down complexity, latency, and scale barriers that have traditionally constrained ML capabilities. Our platform combines Rust-speed performance with elegant tools that developers love to use. Leading companies depend on Chalk for everything from stopping fraudulent credit card swipes, verifying identities, and maximizing clean energy capture. We've recently raised a $50 million Series A , led by Felicis.
