Senior Software Engineer; Middleware
About The Position
Every chart, insight, and experiment result a customer sees in Amplitude passes through the compute layer that this team owns. 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. Our mandate: enable a highly performant, reliable, and flexible way to compute insights. 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. 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.
Requirements
- 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
- Comfort reasoning about tradeoffs between flexibility, performance, and ease of use and making deliberate calls between them
- A track record of owning ambiguous, cross-team projects end-to-end rather than just executing well-scoped tickets
- Strong cross-functional collaboration skills; this team's work only matters in the context of the products built on top of it
Nice To Haves
- 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
Responsibilities
- Design and build core parts of the query/compute engine that powers analysis across Amplitude's product suite
- 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
- Help unify and evolve our core data model, including how non-event data (profile properties, lookup tables, etc.) is represented alongside event data
- Improve the performance, reliability, and scalability of query planning and execution on the Amplitude query engine
- Partner with teams across Session Replay, Experiment, CDP, Query, and frontend to understand their needs and shape the compute layer around them
- Take ownership of projects end-to-end, from design through rollout
Benefits
- Excellent Medical, Dental and Vision insurance coverages, with 100% employer-paid premiums for employee Medical, Dental, Vision on select plans
- Flexible time off, paid holidays, and more
- Generous stipends to spend on what matters most to you, whether that’s wellness (monthly), commuter transit/parking (monthly), learning and development (quarterly), home office equipment (annual), and much more
- Excellent Parental benefits including: 12-20 weeks of Paid Parental Leave, Carrot Fertility Benefits/Adoption/Surrogacy support, Back-up Child Care support
- Mental health and wellness benefits including no cost employee access to Modern Health coaching & therapy Sessions and high quality physician office experience via One Medical membership (select U.S. locations only)
- Employee Stock Purchase Program (ESPP)
- Mentorship programs
- Management training
- Wellness initiatives
