Job description

Overview

At Digital Catapult, we're accelerating the practical application of deep technologies to equip the UK to be future-ready. From AI and advanced media to digital twins, quantum research and next-generation mobile networking, we work at the cutting edge of what's possible. We need an enthusiastic Platforms & Products Security Manager who can bring dedicated security expertise into these innovation domains. You'll assess security posture across our emerging tech platforms, design governance frameworks that enable innovation, and extend our ISO 27001 ISMS into research, experimental, and proof-of-concept environments. You'll partner with product teams to standardise security practices, mentor teams toward secure innovation, and help emerging technologies move safely toward production.

What you’ll do (Duties)

• Assess security risk and maturity across AI systems, advanced media production, mobile networking test labs, digital twins, quantum research, and other emerging tech initiatives to understand their security posture, complexity and readiness for production.
• Prioritise security hardening efforts based on genuine risk, not compliance checklists.
• Design and implement security governance frameworks and decision-making processes that embed security without creating bureaucratic friction.
• Partner with product teams to improve and standardise security practices, sharing guidance and providing support, training and mentorship without direct authority.
• Extend and tailor our ISMS to cover emerging tech domains, balancing compliance with the unique constraints of experimental environments.
• Maintain security posture as experimental systems mature toward production.

Qualifications

• You’ll bring strong and demonstrable security experience in complex, fast-moving technical environments, with a genuine track record of:
  • Risk judgment in experimental contexts – You assess maturity and identify gaps in complex environments; you're comfortable with proportionate, context-aware decisions where textbook solutions don't exist. Previous experience conducting or leading ISO 27001 risk assessments and translating findings into actionable recommendations. Familiarity with other security standards / guidance such as Cyber Essentials Plus would be highly beneficial.
  • ISMS design and governance – You've designed, extended, or tailored security frameworks for diverse organisational contexts; you know how to adapt requirements for research vs. production and established decision-making processes.
  • Influence without authority – You've shaped security practices in teams where you had no direct reporting relationship; you’ll have strong stakeholder management, interpersonal and communication skills and experience of translating technical concepts into understandable business language and build credibility and trust through expertise.
  • Emerging tech exposure – You've worked with AI/ML, cloud, advanced media production, IoT, digital twins, quantum, mobile networking, or similar emerging domains; you're comfortable learning / understanding new technical spaces rapidly.
  • Pragmatism – You distinguish genuine risks from box-ticking; you support innovation while holding the line where it matters; you're resilient in the face of pushback. You hold CISSP, CISM, or equivalent professional security certification demonstrating advanced security knowledge and commitment to the field. An ISO 27001 Lead Auditor qualification is desirable, and emerging tech security certifications (AI security, quantum-safe cryptography, etc.) would be an advantage. Ideally, you've worked in innovation-driven, research-focused, or deep-tech organisations where balancing security with pace is critical.

Deadline for Applications: 22nd February 2026
