- Drive proactive performance engineering through bottleneck detection, architectural guidance, capacity modeling, and runtime tuning.
- Build scalable, self-service performance testing tooling and infrastructure across teams.
- Design and maintain automated load, stress, soak, spike, and capacity test suites with environment-aware execution.
- Embed performance gates into CI/CD pipelines and build dashboards correlating test signals with production telemetry.
- Architect and govern agentic AI-enabled engineering workflows for code review, test generation, release readiness, incident triage, and root-cause analysis.
- Establish guardrails for validation, security, resiliency, auditability, traceability, sensitive-data handling, and reuse of AI-enabled development workflows.
Requirements
- Typically 12+ years of performance engineering experience with high-traffic distributed systems and a strong broader software engineering foundation.
