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.
About the Role
We’re looking for a Developer Relations expert to join our growing GTM team and serve as the technical bridge between Chalk and the AI/ML and data community. This is a hands-on role for someone who deeply understands modern data infrastructure, has experience in sales-led environments, and knows how to create content that actually educates and resonates.
You’ll work closely with sales, product, and marketing to help technical audiences understand how Chalk fits into their stack—across product launches, community engagement, enablement, and outbound motions. From creating long-form technical content to building proof-of-concepts, recording walkthroughs, or leading a live demo, you’ll be a key voice in how we tell the Chalk story.
We work in-person Monday through Friday in our SF and NY offices. We don’t currently offer remote or hybrid positions.
