Security Architect

Please note: You must currently hold UK SC clearance and have DV clearance eligibility.

We are building the future of autonomous maritime operations — and we need a Trust Security Architect who can secure it from the ground up and lead, design and deploy Zero Trust Security across Cloud, IT and Operational Technology. We are an ambitious, technology-driven organisation operating at the frontier of maritime robotics and autonomous systems. Our platforms operate across cloud, edge and embedded environments in some of the most challenging and safety-critical conditions on the planet. Securing them requires a different kind of thinking.

The Role and What You Will Be Doing:

• Leading Zero Trust architecture across cloud, IT, OT and embedded robotic systems — defining trust boundaries, identity models and secure communication patterns.
• Designing secure device identity and attestation frameworks for COTS and proprietary hardware — protecting command-and-control channels from spoofing and adversarial interference.
• Developing secure data-centric architectures for maritime publisher-subscriber networks (ROS, DDS Security) — enabling micro-segmentation, mixed-criticality separation and real-time data validation.
• Embedding cyber-resilience into autonomous decision-making — validating sensor streams (AIS, RADAR, GNSS) and countering tampering and spoofing.
• Aligning security architecture with engineering, operations and defence governance — acting as senior authority for secure network design and long-term security roadmaps.

What We Are Looking For/Must Have Experience:

• Deep expertise in Zero Trust, identity-centric security, secure communications and cryptographic trust frameworks for distributed and resource-constrained systems.
• Proven experience in cyber-physical and embedded security architecture — owning end-to-end security design across cloud, IT and OT environments.
• Ability to operate across mixed COTS and proprietary hardware/software ecosystems — securing high-latency or intermittent networks including satellite, mesh and private 5G.
• Familiarity with secure coding for embedded systems — C/C++, Rust, Python or Go.
• Clear, structured communicator with strong threat-modelling and problem-solving skills — able to align technical and non-technical stakeholders in safety-critical environments.
• You must hold UK SC clearance and have DV clearance eligibility.

Highly desirable:

• Experience with autonomous systems, unmanned vehicles or maritime robotics.
• Familiarity with maritime cyber regulations and class society requirements.
• Knowledge of hardware security modules, PKI for constrained devices and machine-to-machine identity management.
• Understanding of GNSS/GPS spoofing mitigation and resilient command-and-control architectures.

Why This Role?

• You will be shaping the security architecture of genuinely pioneering autonomous maritime systems — this is not a policy or governance role.
• You will work at the intersection of robotics, autonomy, software engineering and cybersecurity — a rare and genuinely exciting technical environment.
• You will have real authority — acting as the senior security voice across the organisation with direct influence on roadmaps, design decisions and engineering direction.
• You will be joining a team that is building something that has never been built before.
