Software Engineer, Senior B Performance Engineering

Senior Software Performance Engineer 6+ Years Experience | PAX India About the Role Help scale the performance engineering discipline across […] — building the tooling, practices, and expertise that let dev and ops teams do their own performance analysis, while staying hands-on enough to solve the hardest problems yourself and mentor others. Our core stack is Kubernetes/Azure-based microservices, though you'll occasionally support older, more monolithic systems too — the core skills (profiling, load testing, root-cause analysis) transfer directly. This is a hands-on coding role: most of your time goes to building and maintaining our load/synthetic test tooling (including AI-assisted testing) and integrating it into our SDLC.

The rest is split between observability tooling and ad hoc performance analysis, with strong ownership of latency, throughput, and resource efficiency. What You'll Do Load & Synthetic Test Tooling Build and maintain our synthetic/load-testing framework — test development (Playwright/Gatling), execution, and reporting. Apply AI capabilities to improve test development — AI-assisted authoring, scenario generation, result analysis.

Integrate performance and synthetic tests into CI/CD pipelines so checks run continuously, not just ad hoc. Observability & Ad Hoc Performance Analysis Improve observability tooling (Splunk, Grafana, Honeycomb, App Insights, App

Dynamics, New Relic): dashboards, alerting, SLIs/SLOs, instrumentation. Run load, stress, and soak
