We strive to create an environment of inclusionone focused on psychological safety empathy and human connectionthat will allow employees of all backgrounds to thrive.

About the Role & Team

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.

Were entering a world where AI agents dont 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. That makes Nova the critical infrastructure in the loop and as non-stop agents become the main source of queries the demand on Novas throughput correctness and operational rigor grows dramatically.

Were looking for a Staff Software Engineer who wants to go deep on both the engine internals and the infrastructure underneath it. Youll work across the full stack of a modern OLAP system query planning and execution columnar storage and encoding distributed compute caching and cloud infrastructure while driving meaningful improvements to performance cost-efficiency and reliability at scale. Youll influence technical direction through your work your design reviews and your mentorship of other engineers on a team of 10.

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 customers.

What Youll Do

Build and evolve core query engine infrastructure

• Work across Novas query execution engine and distributed compute layer: query planning columnar storage formats encoding and compression caching and cluster-level resource management.
• Design and implement new capabilities as Nova expands to support more warehouse-imported data types such as metrics profiles and dimensions.
• Design for high-throughput automated query workloads as AI agents become a primary source of queries ensure Novas architecture supports sustained concurrent and programmatic query patterns at scale.

Drive cost and performance at scale

• Own and execute projects that materially 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 that compound at our scale.
• Build guardrails and observability to catch expensive or pathological queries before they impact the system.

Improve reliability and operational excellence

• Strengthen Novas reliability posture: identify systemic failure modes drive durable fixes and raise the bar on how we detect and respond to production issues.
• Participate in on-call rotation to root-cause incidents and turn one-off fixes into architectural improvements.
• Contribute to capacity planning safe rollout practices and the operational tooling that keeps Nova healthy.

Influence through technical leadership

• Lead the design and execution of multi-month projects that improve Novas architecture performance or capabilities.
• Contribute to technical direction through design docs architecture discussions and code reviews helping the team make principled tradeoffs.
• Mentor senior engineers on distributed systems thinking production debugging and system design.
• Collaborate with Product Middleware Data Pipeline and other engineering teams to ensure Novas capabilities translate into customer value.

Who You Are

You are an experienced systems engineer who:

• Gets energy from working deep inside a complex distributed system understanding how data flows through it where the bottlenecks are and how to make it meaningfully better.
• Has built or significantly extended an OLAP engine columnar database query processor or large-scale data processing system not just operated one.
• Thinks about cost performance and reliability as interconnected concerns not separate workstreams.
• Communicates clearly about technical tradeoffs and earns influence through the quality of your work and ideas not through title.
• Finds it natural to help other engineers level up through pairing design reviews or just being the person who explains the why behind a systems design.

Qualifications

Requirements

• 7 years of industry experience in backend or infrastructure engineering with depth in distributed data systems.
• Hands-on experience building or extending analytical/OLAP systems query engines columnar storage large-scale data processing frameworks or equivalent.
• Track record of driving significant cost optimization on cloud infrastructure at scale (compute storage network).
• Strong computer science fundamentals: distributed systems (partitioning replication consistency failover) data structures and algorithms concurrency and multi-threading performance optimization.
• Production experience with modern cloud infrastructure AWS (S3 DynamoDB EC2) Kafka Redis/ElastiCache Kubernetes Terraform or strong equivalents.
• Proficiency in Java C or Python.
• Demonstrated technical influence beyond your immediate team: leading design discussions driving cross-team alignment mentoring engineers.

Nice to Have

• Experience with specific OLAP or query engine systems: Druid ClickHouse Presto/Trino BigQuery Snowflake or similar.
• Deep JVM expertise GC tuning profiling memory optimization at production scale.
• 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.
