Define and continuously evolve the performance testing strategy.
Ensure test workloads mirror production traffic patterns, regression suites remain green, and alerts are acted upon with documented runbooks.
Instrument the edge fleet for deep observability — latency histograms, resource saturation signals, and tracing pipelines — so performance regressions surface before they reach end users.
Design and enforce staged (A/B, canary) rollout processes for performance-sensitive changes.
Own the feedback loop between test environments and production.
Identify and drive systemic throughput, latency, and efficiency improvements across the edge network — from kernel tuning and eBPF offloads to traffic shaping and caching strategy.
Continuously raise the bar on configuration management, agentic workflows, and automated performance gates.
Reduce toil; increase signal-to-noise in performance data.
Guide ops, dev, and support engineers through technical direction, runbooks, and shared test environments.
Raise the performance literacy of the broader engineering org.
Partner with Product, R&D, Network, Security, and Support teams to ship performance-aware features.
Serve as a subject-matter expert during performance-related incidents and drive post-incident improvements.

Deep expertise in Linux/Unix environments — kernel internals, process scheduling, memory management, and I/O subsystems.
Proficiency with performance profiling and tracing tools: eBPF (bpftrace, libbpf), perf, gdb, strace, flamegraphs, and related tooling.
Strong scripting and automation skills — Python, Bash, and infrastructure-as-code (Ansible, Terraform, or equivalent).
Solid understanding of networking fundamentals: TCP/IP, HTTP/2–3, TLS, load balancing, and traffic engineering.
Experience with cloud platforms (AWS, Azure, GCP) and hybrid/bare-metal edge infrastructure.
Hands-on experience with agentic coding workflows and AI-assisted engineering toolchains.
Excellent communication skills — able to translate low-level performance findings into business impact for diverse audiences.
