We’re looking for an experienced Manual & Automation Tester to join our Technical Excellence Capability Centre, working remotely as part of a collaborative team delivering enterprise-scale solutions across a range of sectors.

This is more than a traditional testing role. Alongside manual and automated testing, you’ll validate infrastructure, environments, deployments and integrations, working closely with Developers, DevOps Engineers and Project teams to ensure every solution is robust, secure and fit for purpose.

What you’ll be doing

As a key member of our QA team, you will:

• Design, execute and maintain manual test plans across infrastructure, backend services and application layers.
• Validate deployments, configuration changes and environment stability across cloud platforms, servers and CI/CD pipelines.
• Perform integration, regression and performance testing across multiple platforms.
• Work closely with Development and Operations teams to identify, troubleshoot and resolve issues early in the delivery lifecycle.
• Automate repetitive testing activities using appropriate tools and frameworks.
• Contribute to the continuous improvement of QA standards, processes and tooling.
• Support the Test Manager and wider delivery teams in achieving successful outcomes.

What we’re looking for

You’ll have at least 3 years’ experience in a testing role within large enterprise environments and be confident working across both manual and automated testing.

You’ll also bring:

• Proven hands-on experience in manual testing, supported by automation testing experience.
• Experience testing large enterprise systems, including Java and Oracle web applications.
• Experience testing Windows 11 and associated applications within an Evergreen environment.
• Knowledge of cloud and infrastructure environments (Azure, AWS or on-premises).
• Experience testing APIs, services and system integrations.
• Hands-on experience with tools such as Postman, Jenkins, JMeter or similar.
• Experience with system integration and data migration testing.
• Strong analytical and problem-solving skills with excellent attention to detail.
• Excellent written and verbal communication skills.
• The ability to understand business processes and translate them into effective testing approaches.
• Proficiency with Microsoft Office applications, including Excel, Word, PowerPoint, Project and Visio.

Desirable experience

• Understanding of networking, containers or CI/CD pipelines.
• Scripting experience with Python, Bash or PowerShell.
• Infrastructure as Code (IaC) validation experience using Terraform or Ansible.
• ISTQB certification.
• Additional technical certifications
