We’re recruiting a Security Engineer to join an established technology business operating across satellite communications, maritime connectivity, defence and government environments.

This is a genuinely hands-on security role. You’ll work across internal and customer networks, helping to design, implement and maintain secure infrastructure while investigating incidents, managing vulnerabilities and improving the organisation’s overall security posture.

The environment is particularly interesting if you enjoy the crossover between cybersecurity, networking and real-world communications infrastructure rather than purely corporate IT security.

You’ll work with networks and systems supporting customers operating at sea, on land and in the air, including highly secure government and defence environments.

You’ll act as a technical specialist for network and device security, taking ownership of security issues from identification through to resolution.

Your responsibilities will include:

• Designing, implementing and maintaining secure network solutions.
• Working hands-on with firewalls, routers, switches and other network security infrastructure.
• Implementing and supporting SIEM and IDS/IPS solutions.
• Monitoring security tools and third-party information to identify threats, vulnerabilities and security events.
• Investigating security incidents and supporting their resolution.
• Performing vulnerability assessments and supporting penetration-testing activities.
• Reviewing CVEs and recommending appropriate remediation.
• Supporting the through-life security of internal and customer networks and systems.
• Testing existing environments for vulnerabilities and recommending improvements.
• Providing third-line support for complex network security issues.
• Advising IT and engineering teams on cybersecurity when designing or changing networks.
• Developing and maintaining security policies, procedures, standards and technical guidelines.
• Producing configuration documentation, schematics and technical support guides.
• Helping colleagues understand and respond appropriately to security threats.
  
  Sharing knowledge and developing security awareness across technical teams.

We’re looking for someone with approximately 5+ years of hands-on network/security experience who is comfortable taking technical ownership rather than simply escalating problems elsewhere.

You should have practical experience with several of the following:

• Cisco firewalls, routers and switches
• SIEM tools
• IDS/IPS technologies
• Vulnerability management
• Penetration-testing tools and techniques
• Network security design and implementation
• Security incident investigation
• Computer forensic tools
• ISO 27001
• GDPR
• Security policies, procedures and technical documentation

You’ll need to be able to explain security issues clearly to both technical colleagues and management and be comfortable dealing directly with customers when required.

We’re particularly interested in people who can combine strong networking fundamentals with practical cybersecurity knowledge
.

Experience with in any of the following would be particularly useful:

• Satellite communications / Sat Com
• Telecommunications
• Maritime communications
• UK MOD or government networks
• Defence technology
• Secure or mission-critical communications environments

Previous Sat Com experience is not essential if your networking and security background is strong.

Because of the nature of the customers and environments…
