Strong background in testing HTTP/API and event/WebSocket traffic.
Proven ability to perform deep performance analysis (latency percentiles, error rates, throughput).
Demonstrated evidence of tracing bottlenecks and building scale-scenarios.
Commitment to working entirely as a hands-on individual contributor.
Design and execute comprehensive load and performance test scenarios.
Analyze complex system metrics to identify throughput limits and latency percentiles.
Trace and isolate infrastructure and application bottlenecks.
Partner with engineering teams to optimize performance for a large-scale platform merger.
