About the role

The Performance Team builds infrastructure that lets developers test, measure, and trust the performance of Apple's search capabilities before release. The role focuses on building and scaling a performance testing platform to capture, replay, and analyze production-scale traffic, enabling dev environments to reflect production behavior and detect regressions.

Responsibilities

  • Design, develop, and operate the performance testing platform that lets developers across Search load-test and validate infrastructure changes before they reach production
  • Build and improve traffic capture/replay and load-generation tooling, along with the pipelines that process the resulting performance data at scale
  • Apply statistical analysis to project how performance results measured in dev environments will translate to production, and to detect regressions before rollout
  • Collaborate closely with product, search, and information intelligence teams to define infrastructure requirements and deliver robust solutions
  • Ensure the health and performance of critical infrastructure by monitoring key metrics, troubleshooting complex issues, and participating in an on-call rotation

Qualifications

  • 5+ years of experience in software development, including designing, building, and operating large-scale distributed systems and backend infrastructure
  • Strong interest in building performance tooling
  • Strong software engineering fundamentals in data structures, algorithms, and system design
  • Excellent communication and collaboration skills to work effectively with cross-functional teams
  • BS, MS, or Ph.D. in Computer Science or a related field, or equivalent experience
  • Statistical/analytical experience projecting how dev-environment results map to production behavior (regression analysis, capacity modeling)
  • Hands-on experience designing load test frameworks: traffic capture/replay, configurable load shapes, concurrency control
  • Experience with observability tooling for root-causing performance regressions
  • Familiarity with Kubernetes, workflow orchestration and CI/CD pipelines for automating test infrastructure
