Senior Qa Engineer

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 escalate 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.
