FULL DESCRIPTION

Director of IT & Security

Build and run the secure internal foundations of a cutting-edge biotech company, protecting data, systems, and workflows in a low-trust environment while enabling fast, reliable scaling.

About the role

We are hiring a Director of IT & Security to design, build, and operate the internal systems and security foundations of [Employer hidden — view at passion-project.co.uk].

This is a hands-on leadership role focused on internal systems, identity, and organisational security.

The role is intentionally centred on building a secure, controlled internal environment that enables rapid and reliable development of our platform, while maintaining clear separation from product and platform engineering responsibilities.

You will take ownership of our internal security posture in a low-trust environment, where sensitive scientific data, proprietary algorithms, and emerging risks — including misuse of AI tools — require strong controls, visibility, and discipline.

Working closely with Engineering, Data, QA/RA, and leadership, you will ensure our internal environment is secure, controlled, and audit-ready, without slowing down the development of our platform.
