• Participate in sprint planning and provide performance risk assessments
• Continuously improve performance testing processes and introduce early-stage performance practices (Shift-left)
• Mentor junior testers and support cross-functional knowledge sharing within the team

• Experience working with Azure Cloud, Azure DevOps CI/CD pipelines, and Node.js-based applications
• Excellent analytical and communication skills for explaining performance risks and findings to technical and non-technical audiences

Nice to Have:

• Experience with additional cloud platforms (e.g., AWS, GCP)
• Familiarity with frontend performance tools (e.g., StiespeedIO, Lighthouse, WebPageTest)
• Knowledge of containerized environments (e.g., Docker, Kubernetes)
