Job summary

Tata Consultancy Services is seeking a Performance Testing Engineer in Bengaluru to execute complex, system-level tests across cloud platforms. You will lead testing initiatives, analyze performance, and collaborate with stakeholders to ensure on-time go-lives.

The role emphasizes deep performance engineering, troubleshooting across cloud services and databases, and using tools like JMeter, AWS/FIS, Gremlin, and Kubernetes. Prior experience in high-traffic environments is valued.

Qualifications

• Experience in performance testing large-scale cloud systems.
• Proficiency with load testing tools such as JMeter (required) and LoadRunner/BlazeMeter.
• Troubleshoot performance issues across cloud services, DBs, and dependent systems.
• Test web, caching, and queuing tech in high-traffic environments.
• Design and run tests for scalable, highly available systems.
• Hands-on experience with AWS/Azure/GCP.
• Familiarity with chaos testing tools like AWS FIS or Gremlin.
• Knowledge of Docker/Kubernetes.
• Coding automated test software is not the primary focus; performance engineering is.

Responsibilities

• Execute performance testing projects with business stakeholders to meet go-live dates.
• Apply QA principles to design and run complex system-level tests.
• Break work into executable tasks aligned to project goals.
• Recommend capacity and scaling parameters for cloud services at launches.
• Communicate test status, findings, and risks to managers and engineers.
• Support junior engineers by reviewing scripts and sharing techniques.
• Unblock tasks and escalate cleanly when needed.
• Share learnings and wins with the team.

Job description

Responsibilities

• Execute performance testing projects in partnership with business stakeholders script, run, and analyze tests to deliver against go-live dates.
• Apply engineering principles to quality assurance - design and run complex, system-level tests across integrated platforms in state-of-the-art QA environments.
• Break assigned work down into executable tasks and sequence them against project objectives.
• Recommend capacity and scaling parameters for cloud services to meet demand during launches and peak events.
• Communicate test status, findings, and risks clearly to project managers and engineering leadership.
• Support less-experienced performance engineers by reviewing scripts, sharing techniques, and pairing on root-cause analysis.
• Unblock yourself where possible and escalation cleanly when you can't.
• Share your work, learnings, and wins with the broader team.

Required Technical Experience

• Performance testing and analysis of large-scale, consumer- and employee-facing enterprise cloud systems.
• Proficiency with load testing tools - JMeter (required), plus LoadRunner, BlazeMeter, or equivalents.
• Deep-dive troubleshooting of application performance issues across cloud services, databases, and dependent systems, with the ability to recommend scaling parameters for production environments.
• Testing web, caching, and queuing technologies in high-traffic environments.
• Designing and running tests against highly scalable, highly available systems.
• Hands-on experience with at least one major public cloud (AWS, Azure, or GCP).
• Chaos testing tools such as AWS Fault Injection Simulator or Gremlin.
• Working knowledge of containerization (Docker, Kubernetes).
• Technical depth is expected, but coding automated test software is not the defining boundary of this role - emphasis is on performance engineering, analysis, and system-level quality.
