Job summary

Across government, the successful adoption of artificial intelligence depends not only on innovation, but on the ability to assure quality, reliability and ethical use at scale. As AI systems become embedded in critical services, robust testing and validation practices are essential to ensure that models perform as expected, outputs are trustworthy and risks are effectively managed. Ofgem plays a vital role in the UK’s energy system, protecting consumers and enabling a more secure, fair and sustainable energy future, and strong assurance of AI-enabled services is critical to delivering this mission.

Ofgem is on an ambitious transformation journey. Within the Digital, Data and Security Services (DDSS) directorate, we are building advanced data and AI capabilities to support innovation, improve efficiency and enhance decision-making. As part of this, we are embedding modern testing practices across digital, data and AI services, ensuring that quality is built into every stage of delivery.

As the Senior Test Engineer for AI , you will play a key role in ensuring the quality and reliability of AI and data-driven solutions. You will lead the design and implementation of testing strategies for complex systems, including AI models, data pipelines and digital services. You will work across multidisciplinary teams, embedding test-driven and behaviour-driven development practices and promoting a culture of quality and continuous improvement.

This is a senior, hands-on technical role requiring strong expertise in testing, automation and AI systems, alongside the ability to influence and mentor across delivery teams.

You will be responsible for:

• Leading the design and execution of test strategies across AI, data and digital services, ensuring alignment with organisational standards and delivery objectives.
• Designing and implementing testing approaches for AI systems, including model validation, data quality assurance and pipeline testing.
• Embedding quality practices such as TDD and BDD across delivery teams, ensuring early and continuous testing throughout the lifecycle.
• Developing and maintaining automated test frameworks and integrating testing into CI/CD pipelines.
• Identifying risks and issues from test results, providing clear insight and recommendations to stakeholders.
• Collaborating with engineers, data scientists and product teams to ensure quality is embedded from design through to deployment.
• Leading defect management processes, analysing trends and supporting continuous improvement in quality and testing practices.
• Championing new testing approaches and tools, including AI-driven testing and predictive analytics.
• Coaching and mentoring team members, contributing to capability development and knowledge sharing across the organisation.
• Ensuring compliance with accessibility, security and governance standards within testing practices.

We are looking for:

A technically strong and forward-thinking testing professional who can lead quality assurance for AI and data-driven systems. You will bring experience in modern testing practices, alongside an understanding of AI and data platforms.

You may come from a testing, QA, data or engineering background, but you will demonstrate:

• Extensive experience managing testing across complex systems, including AI and data platforms
• Strong knowledge of automated testing frameworks and tools within Microsoft-based environments
• A solid understanding of CI/CD, DevOps and cloud-based testing integration
• The ability to analyse risks, manage defects and drive continuous improvement in quality
