Performance Tester

Senior Performance Engineer

6+ Years Experience | Extendable Full-Time Contract | On-site

We're looking for a Senior Performance Engineer who can own the full performance story - from workload modeling to stakeholder sign-off - and make sure our systems never let users down when it matters most.

The opportunity

What you'll be doing

• Lead end-to-end performance testing - from requirements analysis and workload modeling to test planning, execution, and defect management across benchmark, load, stress, and endurance tests.
• Be the trusted advisor on performance strategy - guide client stakeholders on efficient, production-realistic test approaches and translate technical findings into clear, actionable recommendations.
• Dig deep into system behavior - monitor application and system logs, analyze CPU, memory, network, GC, and database metrics to pinpoint bottlenecks and drive resolution with cross-functional teams.
• Own the performance narrative - publish detailed test results and status reports, manage defect tracking in JIRA, and secure stakeholder sign-off at every key milestone.
• Shape test environments and data - set up and maintain test environments, ensure test data accuracy, and collaborate with infrastructure teams on on-premise and cloud deployments (OCP, AWS).
• Champion observability - leverage monitoring tools to track system health proactively, not just reactively.
