Engineering Manager

Machine Learning Engineer

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.

Working directly with our founders, you'll lead a team of exceptional engineers building our platform for real-time inference at scale. This role is a unique opportunity to shape technical architecture and engineering culture at a fast-growing, early-stage company. You'll collaborate with brilliant folks, including Putnam and Advent of Code winners, former Jane Street quants, and Rust compiler contributors — all dedicated to bending the curve of what's possible in ML inference.

We're in the office 5 days a week. When unavoidable conflicts come up, we're flexible. This is not a hybrid role.
