Job Description

Senior Software Engineer role at Amplitude based in San Francisco, CA (onsite). Compensation: USD 165,000 - 276,000 per year. This position centers on the Nova OLAP engine, owning query execution, columnar storage, distributed compute, caching, and cloud infrastructure to enhance performance, cost efficiency, and reliability for a large-scale analytics platform.

Responsibilities

Contribute to Nova's query execution and distributed compute stack, including query planning, columnar storage formats, encoding and compression, caching, and cluster level resource management.
Develop new capabilities as Nova broadens support for additional warehouse-imported data types such as metrics, profiles, and dimensions.
Ensure Nova components withstand high throughput automated query workloads, including queries from AI agents, by designing for sustained, concurrent, and programmatic query patterns 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 through GC tuning, memory management, concurrency, and informed data layout decisions.
Build guardrails and observability to detect expensive or pathological queries before they impact system performance.
Strengthen the reliability of owned Nova components by identifying failure modes, delivering durable fixes, and improving production issue detection and response.
Participate in on-call rotations to root-cause incidents and transform one-off fixes into lasting improvements.
Contribute to capacity planning, safe rollout practices, and the operational tooling that sustains Nova's health.
Design and execute multi-week to multi-month projects within your area of ownership.
Contribute to technical direction through design docs, architecture discussions, and code reviews.
Collaborate with senior and staff engineers to learn and share knowledge with peers through pairing and design discussions.
Work with Product, Middleware, Data Pipeline, and other engineering teams to ensure Nova capabilities translate into customer value.

Requirements

Minimum 3 years of professional experience in backend or infrastructure engineering with exposure to distributed data systems.
Hands-on involvement in building or extending distributed data systems such as query engines, columnar storage, large-scale data processing frameworks, streaming systems, or storage engines.
Experience improving cost or 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.
Demonstrated ability to own and ship substantial components of complex systems and collaborate effectively with engineers and partner teams.
