About the Role

We are seeking an experienced Principal Offensive Security Operator to join a high-performing security function supporting the Ministry of Justice. This is a senior offensive security role focused on conducting safe, realistic and intelligence-led cyber-attack simulations against complex technology estates. You will operate from an adversary perspective, using advanced offensive security techniques to identify weaknesses, validate defensive capabilities and provide actionable insight to support strategic security decision-making. You will be comfortable operating across traditional enterprise environments, cloud platforms and modern digital services, developing complex attack paths while maintaining strong operational security and minimising disruption to business operations.

Key Responsibilities

  • Plan and execute threat intelligence-led, full-spectrum red-team and adversary simulation engagements.
  • Design and conduct complex, multi-phase operations, including exploitation, post-exploitation, persistence and lateral movement.
  • Identify and demonstrate attack paths to high-value systems, users and data.
  • Assess the effectiveness of security controls and wider defensive capabilities.
  • Apply realistic threat-actor tradecraft and operational security principles to minimise detection and operational impact.
  • Develop and maintain attack infrastructure, command-and-control capabilities and supporting automation.
  • Develop tools, techniques and methodologies to enhance offensive security operations.
  • Conduct tactical attack-path analysis across complex technology estates.
  • Translate technical findings and attack scenarios into clear business risk and strategic recommendations.
  • Support vulnerability management, threat mitigation and risk-based cyber security decision-making.
  • Mentor junior Red Team personnel and contribute to the development of offensive security capability.
  • Share offensive security knowledge with security and wider business teams.
