Job Title: Security Architect Lead
Location: Southampton or London (Hybrid)
The Opportunity
Demand for securing cyber physical autonomous maritime systems is accelerating as organisations scale distributed robotic capability and face increasing adversarial and regulatory pressure. This hire sits at the centre of that shift, shaping how trust, identity and resilience are engineered across cloud, edge and embedded environments. The role is focused on moving security from fragmented controls to a unified Zero Trust architecture that can support real time autonomous decision making at scale.
This role will combine:
• Zero Trust architectural leadership (driving structured, end to end security design across cloud, edge, and embedded systems)
• Cross domain technical integration (working closely with robotics, software, systems engineering, operations, and security control teams)
• Risk based cyber physical assurance (ensuring autonomous platforms operate safely, compliantly, and resiliently against advanced threats)
You will ensure that complex, cyber physical autonomous systems are secured with clarity, structure, and control — maintaining alignment between engineering activity, operational constraints, regulatory requirements, and security assurance while
proactively managing risk, dependencies, and system level resilience.
What you will be doing
• Lead Zero Trust architecture across cloud, IT, OT, and embedded robotic systems, defining trust boundaries, identity models, and secure communication patterns
• Design secure device identity and attestation frameworks for COTS and proprietary hardware, protecting command and control channels from spoofing and adversarial interference
• Develop secure, data centric architectures for maritime publisher subscriber networks (ROS, DDS Security), enabling micro segmentation, mixed criticality separation, and real time data validation
• Embed cyber resilience into autonomous decision making, validating sensor streams (AIS, RADAR, GNSS) and collaborating with autonomy and navigation teams to counter tampering and spoofing
• Align security architecture with engineering, operations, and defence governance, while acting as a senior authority for secure network design, long term security roadmaps, and continuous improvement across the organisation
Who you are
• Experienced in cyber physical and embedded security architecture, owning end to end security design across cloud, IT, and OT environments
• Deep expertise in Zero Trust, identity centric security, secure communications, and cryptographic trust frameworks for distributed and resource constrained systems
• Able to operate across mixed COTS and proprietary hardware/software ecosystems, securing high latency or intermittent networks such as satellite, mesh, and private 5G
• Clear, structured communicator with strong analytical, threat modelling, and problem solving skills, able to align technical and non technical stakeholders in safety critical environments
• Experienced collaborating with robotics, autonomy, OT/SCADA, or other high assurance domains, familiar with secure coding for embedded systems (C/C++, Rust, Python, Go) and holding UK SC clearance with DV eligibility
Desirable
• Experience with autonomous systems, unmanned vehicles, or maritime robotics
• Familiarity with maritime cyber regulations, class society requirements, and defence assurance frameworks
• Knowledge of hardware security modules, PKI for constrained devices, and machine to machine identity management
• Experience designing secure architectures for sensor fusion, navigation, or mission critical control systems
• Understanding of satellite communications security, GNSS/GPS spoofing mitigation, and resilient command and control architectures
