  No
• Medical Requirements: No
• Customer Interface: Occasional site-based validation and trials activities
• Budget Responsibility: None

In this role, you will:

• Analyse system requirements, design specifications, and user stories to develop robust validation strategies across software and hardware systems.
• Ensure requirements are clear, complete, and testable, working closely with stakeholders to refine understanding where needed.

• Design, develop, and execute validation plans covering functional, performance, integration, and regression testing.
• Define appropriate levels of automation to maximise test coverage for critical system functionality.
• Specify requirements for validation tools, environments, and supporting infrastructure.
• Investigate, reproduce, document, and track system issues through to resolution.
• Analyse test results and communicate findings clearly to engineering teams and stakeholders.

• Support validation activities at test facilities and customer sites, including Sonardyne’s Plymouth Trials Facility.
• Evaluate system performance under real-world operating conditions, including environmental robustness and repeatability.

• Work closely with software, hardware, firmware, and systems engineering teams to diagnose and resolve issues.
• Contribute to continuous improvement in validation practices across engineering disciplines.
• Maintain strong communication channels across multidisciplinary teams.
• Support the development and expansion of automated testing capabilities.
• Contribute to improvements in validation processes, tools, and methodologies.
• Maintain and develop technical capability through ongoing professional development.

• Proven experience in software or systems validation, including automation testing.
• Solid understanding of the software development lifecycle and CI/CD principles.
• Experience working in structured software engineering environments using source control and peer review practices.
• Strong analytical and problem-solving skills with excellent attention to detail.
• Proven ability to collaborate effectively across engineering teams.
• Experience testing web, Windows, or API-based systems in engineering or technical environments.
• Familiarity with automation frameworks and test tools.
• Exposure to hardware/software integration or embedded systems validation.

• Degree in Computer Science, Engineering, Mathematics, Information Technology, or a related discipline
• Experience in systems engineering, electronics, or embedded software environments

At Sonardyne, you will be part of a team developing cutting-edge subsea technologies used in some of the most demanding environments on Earth. You will contribute directly to the validation of complex systems that operate across global energy, scientific, and defence industries—helping ensure they perform reliably when it matters most.
