Our team sits between Amplitude's front-end analytics products/ rest APIs/ MCPs and Nova, our proprietary analytics database, and owns the compute API that translates a user's question into a fast, correct answer.</p> <p>&nbsp;</p> <p>Our mandate: <strong>enable a highly performant, reliable, and flexible way to compute insights.</strong> Those three goals are often in tension the more flexible we make the system, the harder it is to keep it fast and simple, and a lot of the interesting engineering work on this team lives in that tradeoff.</p> <p>&nbsp;</p> <p>Day to day, you'll work closely with engineers on data management, marketing analytics, Session Replay, Experiment, CDP, Query, and various product teams, since they're all consumers of what we build.</p> <h2>As a Senior Software Engineer, you will</h2> <ul> <li>Design and build core parts of the query/compute engine that powers analysis across Amplitude's product suite</li> <li>Evolve the compute API and semantic layer that other engineering teams build features on top of, so that it can support a more generic table&nbsp;</li> <li>Help unify and evolve our core data model, including how non-event data (profile properties, lookup tables, etc.) is represented alongside event data</li> <li>Improve the performance, reliability, and scalability of query planning and execution on the Amplitude query engine</li> <li>Partner with teams across Session Replay, Experiment, CDP, Query, and frontend to understand their needs and shape the compute layer around them</li> <li>Take ownership of projects end-to-end, from design through rollout</li> </ul> <h2>You'll be a great addition to the team if you have</h2> <ul> <li>Strong backend or distributed-systems engineering experience, ideally touching OLAP databases, query engines, or data infrastructure</li> <li>Experience with SQL, query planning/execution, or building APIs that many other engineering teams depend on</li> <li>Comfort reasoning about tradeoffs between flexibility, performance, and ease of use and making deliberate calls between them</li> <li>A track record of owning ambiguous, cross-team projects end-to-end rather than just executing well-scoped tickets</li> <li>Strong cross-functional collaboration skills; this team's work only matters in the context of the products built on top of it</li> </ul> <h2>Bonus points for</h2> <ul> <li>Experience with large-scale event or time-series data systems</li> <li>Experience designing semantic layers, ORMs, or other data-modeling abstractions</li> <li>Familiarity with columnar databases or OLAP query engines</li> <li>Experience integrating a data platform with external tools or AI/agent workflows</li> </ul> <h2>Example projects you might work on</h2> <p>&nbsp;</p> <ul> <li><strong>New compute schema and parallelization</strong> — redesigning how queries are represented internally to unlock faster, more parallelizable execution.</li> <li><strong>Deeper session-based analysis</strong> — extending
