Learn more at amplitude.com.\nAs 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.\nThe opportunity\nWe'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.\nThat 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.\nWe're looking for a Senior 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.\nThe Impact you will deliver\nBuild the next generation of Nova\nOwn core components across query execution, columnar storage, and distributed compute.\n\nDesign elastic query infrastructure for AI agents as first-class clients, targeting 10× query throughput with predictable performance and lower cost per query.\n\nSolve deep performance problems across engine internals and cloud infrastructure, from JVM and memory optimization to distributed execution.\n\nOwn production reliability through on-call, incident investigation, and architectural improvements that prepare Nova for its next stage of growth.\n\nShape what comes next\nSet technical direction for major initiatives and lead them from proposal through production, with clear milestones and measurable results.\n\nDecide what to build, what to adopt, and how to evolve Nova for its next order of magnitude in scale.\n\nWork across engineering and product to set priorities and resolve trade-offs between capabilities, complexity, and cost.\n\nHelp senior engineers take on larger technical problems through design reviews, debugging, and shared ownership.\n\nWho you are\nYou are a systems-minded engineer who:\nGets energy from working inside complex distributed systems, finding bottlenecks, and making meaningful improvements.\n\nHas built or significantly extended a query engine, storage engine, or distributed data processing system.\n\nMakes sound trade-offs across performance, cost, correctness, and reliability, and builds support for technical decisions across teams.\n\nHelps engineers take on harder problems through design reviews and debugging, while staying open to new ideas and learning from others.\nRequirements\n4+ years of industry experience in backend or infrastructure engineering, with depth in distributed data systems.\n\nHands-on experience building or extending analytical or OLAP systems: query engines, columnar storage, large-scale data processing or streaming frameworks, or equivalent.\n\nTrack record of leading multi-month, cross-team technical projects from design through production, including significant cost or performance wins on cloud infrastructure.\n\nStrong computer science fundamentals: distributed systems (partitioning, replication, consistency, failover), data structures and algorithms, concurrency, performance optimization.\n\nDemonstrated technical influence beyond your immediate team: leading design discussions, driving cross-team alignment, mentoring engineers.\n\nProficiency in Java, C++ or Python.\n\nNice to have\nExperience with query or OLAP systems such as Druid, ClickHouse, Presto/Trino, Spark, BigQuery or Snowflake.\n\nExperience with SQL planning and optimization, or with building SQL layers over heterogeneous storage.\n\nFamiliarity with open table and columnar formats (Iceberg, Parquet, Arrow, ORC) and warehouse-native architectures.\n\nFamiliarity with product analytics, experimentation platforms, event-driven data systems, or serving data to LLM and agent workloads.\n\nAmplitude provides equal employment opportunities (EEO).
