There are still lots of open positions. Let's find the one that's right for you.
As a Principal Engineer on our Advertising, Company Intelligence, and Intent team, you'll help design and implement the core systems that power our real-time marketing platform.

You'll be joining a team with a broad range of ambitious, technically deep projects-from APIs that process tens of billions of events per day, to new buyer intent algorithms powered by LLMs, to a unified B2B identity graph. Depending on your strengths and interests, you'll be matched to the initiatives where you can have the greatest impact. This is a high-growth, high-ownership environment operating at the edge of what's possible in modern software engineering, data infrastructure, and applied AI.
