We are seeking a motivated and enthusiastic Senior SDET (Software Development Engineer in Test) to join a dynamic, cross-functional team working to develop an industry-leading energy trading platform.

• Manage the defect management process, ensuring timely and effective resolutions.
• Test edge cases with a strong focus on understanding customer needs.
• Ensure all releases meet high-quality standards before deployment.
• Collaborate with international teams in an agile setup, occasionally travelling across Europe for planning workshops.

What you bring & who you are:

• Proven track record (4+ years) in delivering manual and automated test frameworks for complex software.
• Proficient in Playwright using TypeScript (Node.js) or similar UI testing frameworks.
• Expertise with Git, Visual Studio Code, Visual Studio, and Azure DevOps.
• Familiarity with Azure Cloud and end-to-end functional and non-functional testing.
