Job description

Join the CX Testing team to validate the quality, performance, and scalability of every release from the customer's perspective. You'll own performance validation end to end — workload design, load/stress/endurance testing, bottleneck analysis, and root-cause triage — across On-prem and SaaS environments. We're looking for someone hands-on and analytical who folds modern AI tooling (agents, LLMs) into the testing workflow to move faster.

What You'll Do

• Design and execute load, stress, endurance, and scalability tests for new features and releases
• Build and maintain automated performance scripts (JMeter, Locust, Gatling, K6, or similar)
• Run API performance testing against REST endpoints and backend systems
• Analyse metrics, isolate bottlenecks, and deliver actionable recommendations to dev teams
• Establish baselines and track performance regressions across releases
• Integrate performance tests into CI/CD pipelines (Jenkins / GitHub Actions)
• Drive performance triage and root-cause analysis through to resolution
• Leverage AI agents and LLMs to accelerate test creation, log/metric analysis, and triage

Must-Have

• 4+ years in performance or API testing only / UI and API Testing
• Load testing framework expertise (Locust/JMeter//Gatling/K6) with Python or Java
• API testing proficiency — REST APIs, HTTP protocols, backend systems
• Strong Python or Java scripting skills
• Performance analysis with observability tools (Grafana, Prometheus, etc)
• Working knowledge of AI tooling — agents and LLMs in a testing/analysis context
• Solid grasp of distributed systems, system architecture, and database context.

Nice-to-Have

• Resource allocation management, reviewing logs, finding RCA.
• Reproducing and triaging real customer-reported production issues
