At Fusebox, we’re helping companies across the world use energy smarter.

Our SaaS platform manages energy flexibility and makes electricity consumption more efficient — helping to build a greener, more sustainable grid.

We’re looking for a QA Engineer who loves digging into details and making sure everything works perfectly — even after dozens of updates.

You’ll play a key role in keeping our energy management software stable, reliable and bug-free through consistent regression testing.

💡 What you’ll do

• Plan, execute and maintain regression and functional testing for our SaaS platform
• Create and manage test cases, identify issues and verify fixes
• Collaborate with developers and product owners to ensure smooth, high-confidence releases
• Work in an environment using CI/CD pipelines, where testing is part of every build
• Suggest improvements to our test processes and help strengthen product reliability

🧠 What helps you succeed

• 2+ years of experience in software testing, ideally focused on regression testing cycles
• Solid understanding of testing methodologies – regression, smoke, functional and integration testing
• Hands-on experience in test design, bug management and documentation
• Familiarity with CI/CD pipelines – you’ve worked in environments where tests run automatically as part of releases (e.g. GitHub Actions, GitLab CI)
• Bonus: Experience with Playwright, Cypress, Selenium, or Postman
• Basic understanding of Git and API testing
• Analytical, thorough and proactive — you see testing as a craft, not a checklist

⚙️ How you work

• You notice the small details that others miss
• You take ownership and make sure testing runs end-to-end — from planning to reporting
• You communicate clearly and collaborate closely with developers
• You continuously look for ways to improve how testing is done and make releases smoother

🌱 Why Fusebox

• Freedom to shape how testing is done and make a real impact on product quality
