Job Summary
Design and build core parts of the query/compute engine powering analysis across Amplitude's product suite, evolving the compute API and semantic layer to support generic tables. Improve performance, reliability, and scalability of query planning and execution while unifying the core data model for non-event data alongside event data. Partner with teams across Session Replay, Experiment, CDP, Query, and frontend to shape the compute layer around their needs, taking ownership of projects end-to-end from design through rollout.
Required Qualifications
- Strong backend or distributed-systems engineering experience, ideally touching OLAP databases, query engines, or data infrastructure
- Experience with SQL, query planning/execution, or building APIs that many other engineering teams depend on
- A track record of owning ambiguous, cross-team projects end-to-end rather than just executing well-scoped tickets
- Strong cross-functional collaboration skills
Desired Qualifications
- Experience with large-scale event or time-series data systems
- Experience designing semantic layers, ORMs, or other data-modeling abstractions
- Familiarity with columnar databases or OLAP query engines
- Experience integrating a data platform with external tools or AI/agent workflows
