About the role

  • Every AI insight, every experiment, every cohort at Amplitude starts with a query.
  • 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 thousands of product teams worldwide.
  • We're entering a world where AI agents don't just assist product teams - they ship features, run experiments, and make prioritization calls autonomously.

Responsibilities

  • Build and improve core query engine components
  • Implement new capabilities as Nova expands to support more warehouse-imported data types, such as metrics, profiles, and dimensions.
  • Help ensure Nova's components support high-throughput automated query workloads - as AI agents become a primary source of queries, build for sustained, concurrent, and programmatic query patterns at scale.
  • Own and execute projects that reduce infrastructure cost - compute, storage, network, and memory - while maintaining or improving latency and throughput.
  • Profile and optimize JVM performance: GC tuning, memory management, concurrency, and data layout decisions.
  • Build guardrails and observability to catch expensive or pathological queries before they impact the system.
  • Strengthen Nova's reliability posture in the components you own: identify failure modes, drive durable fixes, and raise the bar on how we detect and respond to production issues.
  • Lead the design and execution of multi-week to multi-month projects within your area of ownership.
  • We've made significant investments in talent and infrastructure to build the most powerful AI analytics platform on the market.

Requirements

  • 3+ years of industry experience in backend or infrastructure engineering, with exposure to distributed data systems.
  • Experience improving cost or performance on cloud infrastructure (compute, storage, network).
  • You are a systems-minded engineer who:
  • Production experience with modern cloud infrastructure - AWS (S3, DynamoDB, EC2), Kafka, Redis/ElastiCache, Kubernetes, Terraform - or strong equivalents.
  • Proficiency in Java, C++, or Python.
  • Requirements
  • Hands-on experience building or extending distributed data systems - query engines, columnar storage, large-scale data processing frameworks, streaming systems, storage engines, or equivalent.
  • Strong computer science fundamentals: distributed systems (partitioning, replication, consistency, failover), data structures and algorithms, concurrency and multi-threading, performance optimization.
  • Demonstrated ability to own and ship significant pieces of complex systems, and to collaborate effectively with engineers and partner teams.

Nice to have

  • Experience with specific OLAP or query engine systems: Druid, ClickHouse, Presto/Trino, BigQuery, Snowflake, or similar.
  • JVM expertise - GC tuning, profiling, memory optimization.
  • Experience with columnar data formats and encodings (Arrow, Parquet, ORC, or custom formats).
  • Familiarity with product analytics, experimentation platforms, or event-driven data systems.
  • Contributions to open-source data infrastructure projects or published work in the data systems space.
  • Humility: We operate from a place of empathy and openness, seeking to understand many points of view.
  • Growth Mindset: We're tenacious in the face of challenges and seek feedback in order to grow ourselves and others.
