In this role, you will

Design, build, and execute performance, load, stress, and soak tests for complex enterprise applications.
Create and maintain performance test scripts using Apache JMeter.
Instrument and monitor application and infrastructure during tests (APM/logs/metrics) to capture response times, throughput, errors, CPU/memory/GC, DB performance, network, and queue behaviour.
Analyze test results and system metrics to diagnose bottlenecks, memory leaks, latency issues, and throughput constraints.
Monitor system, application, database, and server performance during test execution.
Perform root cause analysis (RCA) on performance problems and provide actionable recommendations to architecture and development teams.
Participate in Agile ceremonies and contribute to continuous performance improvements.

Work Model

Based on this role’s business requirements, this is a hybrid position requiring 4 days a week in a client or Cognizant office in Toronto, ON.

Demonstrate excellent Linux fundamentals and solid understanding of diagnosing system utilization.
Experience working with large scale distributed systems & large data volumes.
Strong analytical and problem-solving skills, with the ability to diagnose performance issues and propose effective solutions.

These will help you stand out

Experience with Chaos Engineering & Observability is nice to have to transition towards an SRE role.
