Principal Software Engineer - Performance Engineering (Cloud Infrastructure)

Highlights

• Drive cloud infrastructure performance strategy across major providers.
• Translate benchmark data into pricing and rollout decisions.
• Partner directly with cloud and silicon partners on new hardware.

Ideal candidate

A curious, low-ego infrastructure leader who geeks out on hardware internals and turns data into business decisions. You thrive with autonomy, mentor others, and love partnering across engineering, finance, and cloud providers.

Requirements

• 12+ years of experience in performance engineering, systems engineering, or infrastructure engineering, with a track record of principal-level technical leadership.
• Deep expertise in cloud infrastructure performance across at least one major CSP (AWS, Azure, or GCP), including instance types, pricing models, and capacity constraints.
• Strong grounding in hardware/systems fundamentals: CPU microarchitecture, memory bandwidth, I/O subsystems, and use of profiling tools (PMU counters, etc.) to root-cause performance bottlenecks.
• Experience building or operating large-scale benchmarking systems (e.g., TPC-DS-style workloads) and turning benchmark output into actionable optimization strategies and pricing/rollout decisions.
• Ability to build quantitative models connecting technical performance metrics to business outcomes (pricing multipliers, cost-per-query).
• A track record of leading cross-functional, cross-company initiatives — comfortable being the primary technical point of contact with external hardware and cloud partners (CSPs, silicon vendors).
• Bias toward automation: builds scorecards, dashboards, and validation pipelines rather than relying on one-off analysis.
