About Chalk

Chalk (chalk.ai) is the platform for production AI. Trusted by enterprises including Whatnot, Grindr, Mission Lane, Turo, and Apartment List, Chalk brings together context, runtime, and learning for agents and models. Chalk’s Context Engine delivers live context by querying data across warehouses, databases, streams, and APIs, straight from the source. Chalk’s runtime powers agents and models with infrastructure and governed access to LLMs and tools. Together, these capabilities help teams build AI that understands their business, continuously improves, and runs reliably in production. We've recently raised a $50 million Series A, led by Felicis.

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 are hiring Software Engineers to join our team. This is an opportunity to join us in-person as an early employee and make a large impact at a high growth start-up. You will tackle challenging engineering problems with a high degree of autonomy and ownership. 

We are looking for software engineers who are comfortable solving business problems across all layers of the software stack. At Chalk, we build reliable data processing systems that can operate performantly at scale with a laser-focus on developer experience.

We need engineers who can build world-class user experiences across CLI and web surfaces, while also understanding and contributing to a codebase that contains ideas from compilers, query planners, and distributed systems.

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

What you will do

• Work directly with Chalk’s co-founders to productionize our first iteration

• Write TypeScript, Python, Go, and React

• Expose the functionality of our core platform to data scientist and machine learning end-users in their home environments

• Iterate rapidly to improve Chalk’s platform in response to customer needs

What we’re looking for

• 4+ years experience of professional software engineering experience

• Working knowledge of computer science fundamentals. We’re not looking for experience from drilling leet code – we need folks who are comfortable building and maintaining real systems

• A record of developing sophisticated user-facing applications that are pleasant to use

• An eye for high-quality UX

• Track record of learning new concepts quickly

• Ability to work autonomously & to make pragmatic tradeoffs with an eye towards business outcomes

• Strong communication skills

• Bachelor's degree in Computer Science or equivalent

Bonus points

• Experience implementing data infrastructure

• Experience working with developer tools

• Experience with applied machine learning or data analytics

• Experience with Go
