Your future duties and responsibilities
Are you a meticulous Software Tester with a passion for delivering robust, high-performing systems in complex environments?
We are seeking a skilled and motivated Automation Tester to join our dynamic team. This role is ideal for someone with a strong background in software testing—particularly within the Defence sector—who can bring both hands-on testing expertise and strategic thinking to new, high-impact projects.
If you thrive in fast-paced environments and have a deep understanding of testing Defence systems and setting up test strategies from the ground up, we’d love to hear from you.
Key Responsibilities:
* Design, develop, and implement comprehensive test strategies for new Defence-related software projects.
* Evaluate software applications to identify bugs, security issues, and performance bottlenecks.
* Execute manual and automated test cases, ensuring compliance with Defence standards and project-specific requirements.
* Collaborate closely with developers, analysts, and stakeholders to define acceptance criteria and resolve issues efficiently.
* Develop and maintain test plans, test scripts, and test documentation aligned with MOD standards and policies.
* Ensure delivered systems meet functional, non-functional, and security requirements, with a strong emphasis on traceability and auditability.
Required Qualifications To Be Successful In This Role
* Strong background in software testing within the Defence or secure government sectors.
* Experience creating and executing test strategies from inception, especially for new or greenfield projects.
* Familiarity with MOD systems, policies, and secure environments.
* Solid understanding of automation frameworks, tools (e.g. Selenium, JUnit, etc.), and continuous integration pipelines.
Desired Skills:
* Interest in the latest testing methodologies, tools, and industry trends.
* Knowledge of programming languages.
* Experience in test report and script writing.
