Senior Test Performance Engineer

Our requirements

• Experience (3+ years) in software engineering or test automation, with a strong automation mindset
• Solid coding skills in C# (or similar modern language)
• A proactive approach—you enjoy designing solutions, not just executing tasks
• Performance testing tools (e.g., JMeter or similar)
• UI automation frameworks (e.g., Playwright, Selenium, Selenoid)
• CI/CD and engineering tools (Docker, Jenkins, Git, Jira/XRay)
• Working across Windows & Linux environments
• Understand modern software testing and Agile delivery

• Good English communication skills.

Optional

• Experience with AI in testing (e.g., GitHub Copilot, MCP concepts)
• Familiarity with Elastic Stack or messaging systems (RabbitMQ)
• Exposure to hardware simulation or end-to-end system testing

Your responsibilities

• Drive performance quality: Design and execute performance strategies covering UI and API layers (load, stress, and beyond)
• Build smart automation: Create scalable, reusable test frameworks and scripts that simulate real-world usage
• Turn data into insight: Analyze performance metrics, identify bottlenecks, and help teams make data-driven decisions. Be part of the engineering flow. Embed performance testing seamlessly into CI/CD pipelines
• Enable great environments: Shape test data strategies and ensure systems are observable, stable, and ready to scale
• Elevate quality standards: Track meaningful KPIs (e.g., critical path coverage, defect escape) and continuously improve engineering practices
• Coach and collaborate: Review code, share best practices, and help teams build testable, high-quality systems
• Own problems end-to-end: Triage issues, perform root cause analysis, and implement long-term solutions—not just fixes
• Keep knowledge flowing: Maintain clear, living documentation and playbooks
