What we're looking for

We're keen to speak with established cybersecurity leaders who combine strong technical foundations with the ability to influence, build and deliver.

You'll ideally bring:

Proven experience building, scaling or transforming security engineering programmes within a product-led or technology-driven organisation.Strong application security expertise, including OWASP, API security, SAST, DAST, threat modelling and secure development practices.Experience securing cloud environments, data platforms and pipelines, with knowledge of IAM, Kubernetes, containers and cloud-native security tooling.A solid understanding of AI and LLM security risks, controls and governance, with the ability to guide the secure adoption of emerging technologies.Experience overseeing security operations, including SIEM improvement, incident response and relationships with outsourced SOC providers.A track record of leading and developing technical security teams while building strong relationships with engineering and product stakeholders.Experience managing penetration-testing partners and external security vendors.The ability to translate complex technical risks into clear, actionable decisions for both technical teams and senior executives.

The leadership style that will thrive

You're a builder who takes ownership, makes risk-based decisions and focuses on meaningful outcomes. You understand that effective security isn't simply about adding controls - it's about helping people make better decisions, enabling innovation and making secure ways of working the natural choice.

You're curious about emerging technology, comfortable operating at both strategic and technical levels, and motivated by the opportunity to develop people, improve maturity and make a lasting impact.

Why consider this opportunity?
