Infrastructure Tester

As our Infrastructure Tester, you'll join a dedicated, high-performing team delivering secure, scalable, and high-quality solutions within the Defence and Security sector.

You'll work in a collaborative environment where your ideas and expertise are valued, supporting the delivery of infrastructure that underpins mission-critical systems.

The role offers a broad range of testing activity, including validating performance, reliability, and security requirements across complex environments.

You'll be supported to develop your technical skills and progress your career through training, development opportunities, and exposure to meaningful, high-impact work.

We can offer great career progression opportunities, benefits which you can flex to meet your needs, and training and development opportunities.

• Validating and verifying infrastructure components, systems and networks to ensure performance, reliability and security requirements are met.
• Carrying out functional and non-functional testing across physical and virtual infrastructure.
• Performing end-to-end integration testing.
• Analysing test results and producing clear and accurate documentation.
• Managing test activities independently and contributing to project delivery.
• Supporting the continuous improvement of test approaches, tooling, and frameworks.

• Experience working in Infrastructure Test roles such as Infrastructure Test Support or Infrastructure Test Engineer.
• A strong technical background in Windows Client and Server operating systems across physical and virtual environments.
• Experience of end-to-end integration testing.
• ISTQB Foundation Level certification, preferably up to Advanced Level Technical Test Analyst or equivalent qualifications.

It would be great if you had:

• Knowledge of Windows 10 or 11 and Windows Server 2019, 2022 or 2025.
• Experience with VMware, Hyper-V or Citrix.
