Technical Writer

Chalk•Los Angeles, CA

About The Position

Chalk is building the data platform that powers the future of machine learning. We tear down barriers of complexity, latency, and scale 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 and identity verification to maximizing clean energy capture. We're a fast-moving, technically elite team composed of Advent of Code winners, former Jane Street quants, and Rust compiler contributors. If you’re excited by infrastructure, performance, and developer experience, you’ll be in good company. We’re looking for Chalk’s first Technical Writer — someone who can read code like a book and turn complexity into clarity. Your writing will be the first touchpoint for many engineers exploring Chalk and a trusted guide for those building with it. This is a foundational role with outsized impact. You’ll work closely with engineering, product, and developer advocacy to define our documentation strategy from the ground up. Whether you’re explaining how our symbolic Python interpreter works or guiding a team through real-time feature engineering, your work will make Chalk more accessible, discoverable, and powerful.
