🎯 The Role

The Role:

Key Responsibilities:

• Establish performance, throughput, latency, and capacity baselines for critical customer and platform workflows
• Define and maintain SLOs, error budgets, performance budgets, dashboards, alerts, and reliability thresholds
• Identify system bottlenecks and lead cross-functional remediation efforts with engineering teams
• Build capacity models that show what the platform can sustain, where constraints will emerge, and what additional scale will cost
• Lead load, stress, soak, spike, failure, and recovery testing in representative environments
• Develop realistic demand scenarios for major customers, partnerships, pilots, and high-volume events
• Drive architecture hardening, graceful degradation, dependency-failure planning, and resilience improvements
• Partner with Test Automation and Scalability Engineering to establish automated performance testing, regression coverage, and production release gates
• Own technical readiness assessments for major pilots, partnerships, and production launches
• Create operational runbooks for scale-up events, incidents, rollback, recovery, and dependency failures
• Lead performance and reliability investigations during incidents and ensure lessons are incorporated into future engineering work
• Make infrastructure cost, performance, and reliability tradeoffs visible to engineering and executive leadership
• Recommend capacity and reliability investments before they become production constraints

📌 Required Qualifications

• Significant experience in Site Reliability Engineering, performance engineering, platform engineering, distributed systems, or a closely related engineering discipline
• Experience supporting production systems with meaningful scale, traffic, latency, or availability requirements
• Deep understanding of observability, performance analysis, capacity planning, and reliability engineering
• Strong hands-on experience with cloud infrastructure and production distributed systems
• Deep knowledge of databases, networking, caching, queueing, compute, storage, and common distributed-system failure modes
• Experience defining and operating against SLOs, SLIs, error budgets, and production reliability metrics
• Hands-on experience performing load, stress, soak, scalability, and resilience testing
• Ability to profile systems, diagnose bottlenecks, tune architecture, and work directly with engineering teams to implement improvements
• Experience designing for graceful degradation, dependency failures, recovery, and high-demand scenarios
• Strong incident management and root-cause analysis experience
• Ability to translate technical performance and reliability risks into clear business implications for senior leadership
• Strong judgment around when systems genuinely require optimization versus when additional complexity is premature

⭐ Desirable Experience

• Experience operating high-scale SaaS, identity, DNS, registry, infrastructure, or other highly distributed platforms
• Experience creating capacity-cost models and forecasting infrastructure requirements
• Experience building performance and reliability gates into CI/CD pipelines
• Experience preparing platforms for significant increases in traffic associated with enterprise customers or strategic partnerships
• Experience leading reliability or performance initiatives that span multiple engineering teams
