What We’re Looking For

We value people who take ownership, think critically, and enjoy working as part of a collaborative team tackling complex challenges. You don’t need to tick every box, but we’re particularly interested in people with skills/experience as follows:

• Proven leadership experience managing teams in a cybersecurity or technology delivery environment
• Strong stakeholder management skills, with the ability to influence at senior levels and navigate complex organisational structures
• Experience of delivering security across large-scale programmes or portfolios.
