About the role

  • Benchmark design & execution: Build and maintain repeatable end-to-end benchmarks for database and AI workloads
  • Database performance engineering: Evaluate throughput, latency, concurrency, scalability, and stability across OLTP/OLAP and mixed workloads.
  • AI performance benchmarking: Measure and optimize performance for GPU/CPU inference pipelines, model serving, and data/feature pipelines; assess cost/performance tradeoffs.
  • Tooling & automation: Develop harnesses, scripts, dashboards, and reproducible environments to run benchmarks consistently.
  • Analysis & reporting: Produce clear reports, identify bottlenecks, and recommend fixes.
  • Cross-functional collaboration: Partner with database engineers, AI engineers, the field teams and product management to define performance goals and acceptance criteria.
  • Performance best practices: Establish standards for test hygiene, statistical rigor, hardware normalization, and benchmark governance.

Requirements

  • 8+ years in performance engineering, benchmarking, SRE, or systems engineering (database and/or AI systems).
  • Strong understanding of performance concepts and stochastic modeling: latency percentiles, tail behavior, throughput, concurrency, queueing, saturation, and capacity planning.
  • Strong understanding of database internals (Postgres or equivalent databases).
  • Hands-on experience benchmarking databases and/or distributed systems (e.g., Postgres or similar).
  • Experience with benchmarking tools and harnesses (examples: pgbench, HammerDB, TPC-like workloads, custom harnesses).
  • Proficient in Python and/or Go for automation and data analysis, strong scripting skills (Bash), skills in eBPF.
  • Experience with Linux performance profiling (e.g., perf, flamegraphs, strace, iostat, vmstat).
  • Ability to communicate findings clearly and drive performance improvements with engineering teams.
Benefits
  • access to CuraLinc to aid employees in health and wellness tips and practices
  • Wellness Fridays extending to December 2026
