An opportunity has arisen for a senior cyber security leader to define and drive the security architecture for a next-generation satellite communications and space infrastructure programme spanning both space and ground segments.
This is a high-impact technical leadership role with end-to-end responsibility for cyber security, lawful intercept, and secure communications architecture across mission operations, network infrastructure, and spacecraft systems. You will act as the primary technical authority for security design, ensuring resilience, compliance, and operational integrity are embedded throughout the full programme lifecycle.
You will shape and govern the security architecture of a complex, multi-domain satellite communications environment, covering mission operations centres, core networks, gateway infrastructure, and onboard spacecraft systems. The role also includes significant involvement in regulatory compliance and security assurance activities for government and commercially sensitive environments.
Key Responsibilities
- Lead the design and implementation of lawful intercept capabilities across gateway and terrestrial network environments
- Define and maintain the overall cyber security architecture across mission operations, network control systems, core networks, and ground infrastructure
- Ensure data sovereignty, localisation, and regulatory requirements are embedded into system and network design
- Lead space segment security design, including command authentication, anti-spoofing measures, secure communications links, and onboard cryptographic controls
- Support security clearance processes, regulatory submissions, and responses to technical assurance findings
- Plan and coordinate penetration testing, red-team activities, and end-to-end security audits across the programme
- Act as final technical authority for security architecture approval prior to operational deployment
- Collaborate closely with systems engineering, spacecraft engineering, network engineering, and operations teams to ensure security is embedded throughout the lifecycle
Essential Skills & Experience
- 12+ years’ experience in cyber security, telecommunications, satellite communications, defence, or critical infrastructure environments
- Proven experience delivering or managing lawful intercept capabilities in telecoms or secure communications systems
- Strong background in cyber security architecture and secure systems engineering
- Experience working on regulated or security-cleared programmes
- Knowledge of secure space communications, including authentication, anti-spoofing, and cryptographic protection techniques
- Relevant certifications (e.g. CISSP, OSCP, CEH or equivalent) desirable
- Strong technical leadership and stakeholder management capability
- Degree or postgraduate qualification in Cyber Security, Computer Science, Telecommunications, or related field
Desirable Experience
- Exposure to satellite communications networks, NTN architectures, or defence-grade secure communications systems
- Familiarity with secure communications standards and frameworks (e.g. CCSDS SDLS, NIST)
- Experience with integrated space and ground segment infrastructure programmes
- Knowledge of secure cloud platforms, virtualised network environments, or 5G core systems
- Experience managing third-party security assurance, audits, or supplier security reviews
What’s on Offer
- A leading role shaping the security architecture of a next-generation satellite communications programme
- Significant technical ownership and influence across programme delivery
- Flexible and remote working options
- Long-term involvement across development, deployment, and operational phases
- Collaboration within an international engineering environment focused on advanced space technologies
