Senior Offensive Security Engineer

HOURS: 36

THE ROLE

The Offensive Security Unit (OSU) forms part of the Government’s wider Laboratory for AI Security Research initiative, which brings together academia, industry, and government to advance UK leadership in AI security research.

Without truly understanding the future of cyber-attacks we are limited in our ability to defend. OSU will be a dedicated team that will identify, design and assess new AI-enabled offensive techniques.

As a Senior Offensive Security Engineer, you will build and run the systems, tooling, and environments that turn research ideas into reliable, repeatable evidence. Outputs may include prototype implementations, testing environments, reproducible evaluations, experimental designs, technical reports, demonstrations, and briefings for government partners. All work will be conducted within appropriate legal, ethical, and governance frameworks.

We are particularly interested in candidates with an engineering mindset and a background in cyber who want to harness modern AI techniques. Deep machine-learning expertise is welcome but not required; what matters most is strong engineering judgement, experimental rigour, and the ability to build technical fluency quickly.

HOW YOU’LL MAKE AN IMPACT

• Lead the development of prototypes, tools, infrastructure, and evaluation harnesses
• Stand up and own the realistic test environments and ranges that allow offensive techniques to be run safely and meaningfully.
• Build and maintain reproducible implementations that support rigorous evaluation of AI-altered attack surfaces, including discovery, chaining, automation, or amplification of cyber techniques.
• Contribute to the design and running of controlled experiments by advising on feasibility, instrumentation, measurement, and implementation quality.
• Produce clear technical evidence through reports, demonstrations, and briefings.
• Work closely with government and technical stakeholders to ensure research remains grounded, relevant, and actionable.
• Mentor and guide other research engineers, contributing to overall team capability

YOU’LL THRIVE IN THIS ROLE IF YOU

• Have strong instincts for technical implementation and are curious about how systems can be built, probed, stressed, and evaluated.
• Are energised by anticipating where offensive capability is heading, and by building the tools, environments and experiments needed to understand it.
• Enjoy turning ideas into working prototypes and concrete evidence.
• Are comfortable working in ambiguous problem spaces where the right questions are not always obvious
• Are motivated by producing work that has real operational relevance and impact
• Like collaborating across disciplines, particularly with researchers and domain experts
• Communicate clearly with both technical and non-technical audiences
• Help shape OSU’s experimentation culture, methods, and technical standards
