What you'll do

As a QA Engineer at Mercury, you'll play a key role in ensuring the quality and reliability of our market-leading SaaS platform. Working as part of an Agile, cross-functional development team, you'll collaborate closely with Developers and Product Owners to test, refine and deliver high-quality software.

• Work with Developers to test user stories as they're being built, providing fast and actionable feedback.
• Log and track defects in Azure DevOps, helping the team prioritise effectively.
• Participate in regression and release testing cycles.
• Collaborate with other QA Engineers to continuously refine testing practices and improve quality across the team.

You'll be someone who takes pride in quality, thinks critically, and enjoys balancing technical depth with user empathy.

We're looking for:

• Demonstrable experience across the software testing lifecycle, from planning through to execution and defect management.
• Hands-on experience with both manual and automated testing using Selenium WebDriver with C# for UI automation.
• Knowledge of API testing tools such as Postman, ReadyAPI, or Swagger.
• Experience working in an Agile environment.
• A solution-focused mindset with strong critical-thinking and analytical skills.
• Excellent attention to detail and the ability to assess priorities logically.

Bonus points for:

• Experience with performance or load testing (JMeter).
• Exposure to CI/CD environments and build pipelines in Azure DevOps.
• Knowledge of Microsoft Dynamics 365 or the Power Platform.
• ISTQB Foundation certification.
