Job Description

Amplitude is seeking a Senior Software Engineer to help advance the Nova OLAP engine from our San Francisco campus. In this onsite role, you’ll own critical aspects of query execution, columnar storage, and the distributed compute stack, while shaping caching strategies and cloud infrastructure to boost performance, cost-efficiency, and reliability for a large-scale analytics platform. The compensation for this position ranges from USD 165,000 to 276,000 per year.

Responsibilities

Collaborate across Nova's query execution and distributed compute layers, covering query planning, columnar storage formats, encoding and compression techniques, caching approaches, and cluster-wide resource management.
Develop new capabilities as Nova broadens support for additional warehouse-imported data types, including metrics, profiles, and dimensions.
Ensure Nova remains capable of handling high-throughput automated query workloads, anticipating AI-driven queries and designing for sustained concurrency and programmatic access at scale.
Lead initiatives to reduce infrastructure costs across compute, storage, network, and memory while maintaining or improving latency and throughput.
Profile and optimize JVM performance, focusing on garbage collection tuning, memory management, concurrency, and data layout decisions.
Build guardrails and observability to detect expensive or pathological queries before they affect system performance.
Improve the reliability posture of Nova components you own by identifying failure modes, delivering durable fixes, and enhancing productionIssue detection and response.
Participate in on-call rotations to root-cause incidents and translate one-off fixes into lasting improvements.
Contribute to capacity planning, safe rollout practices, and the operational tooling that keeps Nova healthy.
Design and execute multi-week to multi-month projects within your domain of ownership.
Contribute to technical direction through design docs, architecture discussions, and code reviews.
Pair with and learn from senior and staff engineers, then share insights with peers.
Collaborate with Product, Middleware, Data Pipeline, and other engineering teams to ensure Nova capabilities translate into customer value.

Requirements

At least 3 years of experience in backend or infrastructure engineering with exposure to distributed data systems.
Hands-on work building or extending distributed data systems such as query engines, columnar storage, large-scale data processing frameworks, streaming systems, or storage engines.
Experience reducing cost or improving performance on cloud infrastructure, including compute, storage, and network.
Strong computer science fundamentals in distributed systems (partitioning, replication, consistency, failover), data structures and algorithms, concurrency and multi-threading, and performance optimization.
Production experience with modern cloud infrastructure such as AWS (S3, DynamoDB, EC2), Kafka, Redis/ElastiCache, Kubernetes, Terraform, or strong equivalents.
Proficiency in Java, C++, or Python.
Proven ability to own and deliver significant components of complex systems and collaborate effectively with engineers and partner teams.
