About the role

We are hiring a Director of IT & Security to design, build, and operate the internal systems and security foundations of Portal Biotech.

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.

• Experience with endpoint security, MDM, and device management

• Strong knowledge of cloud security fundamentals (focused on internal/corporate environments)

• Experience mitigating data leakage risks, including AI tool misuse and shadow IT

• Ability to clearly separate and coordinate with product/platform engineering responsibilities

Desirable

• Experience with ISO 27001, NIST 800, or Cyber Essentials (plus)

• Familiarity with GxP, or regulated environments

• Experience supporting audits or certification processes

• Exposure to scientific or data-intensive organisations

• Relevant certifications (CISSP, CISM, cloud security)
