As an organization, we deliver for our customers by living our values. We operate from a place of humility, take ownership of problems and successes, approach challenges with a growth mindset, and put our customers at the center of everything we do.

THE OPPORTUNITY

We're entering a world where AI agents don't just assist product teams, they ship features, run experiments, and make prioritization calls autonomously. What makes that possible is agents' ability to verify their work against real product data continuously. Our in-house OLAP engine, Nova, processes trillions of events in real time, turning raw behavioral data into fast, trustworthy answers that power decisions for tens of thousands of agents and product teams worldwide.

That makes Nova the critical infrastructure in the loop, and as non-stop agents become the main source of queries, the demand on Nova's throughput, correctness, and operational rigor grows dramatically.

We're looking for a Staff Software Engineer who wants to go deep on the engine internals and the infrastructure underneath. You'll own significant components of a modern OLAP system, across query execution, columnar storage, distributed compute, caching, and cloud infrastructure, and drive meaningful improvements to performance, cost-efficiency, and reliability. This role is ideal for someone who finds real satisfaction in making a complex distributed system faster, cheaper, and more reliable — and who wants to do that work on a system that directly powers the product experience for thousands of enterprise customers.

THE IMPACT YOU WILL DELIVER

Build the next generation of Nova

• Own core components across query execution, columnar storage, and distributed compute.
• Design elastic query infrastructure for AI agents as first-class clients, targeting 10× query throughput with predictable performance and lower cost per query.

• Own production reliability through on-call, incident investigation, and architectural improvements that prepare Nova for its next stage of growth.

Shape what comes next
