Key Skills

The successful Senior Security Engineer will ideally have experience across several of the following:

• Enterprise firewalling, firewall policy, firewall hardening and firewall management
• Palo Alto Networks, Panorama, GlobalProtect, threat prevention, NAT, VPN, App-ID / User-ID
• Cisco ASA, FTD, ISE, secure routing and switching
• Elastic Stack, Elasticsearch, Kibana, Beats, Logstash, Elastic Security, SIEM or security monitoring

• Windows Server hardening, Active Directory, Group Policy and endpoint security
• CIS Benchmarks, STIGs and practical hardening standards
• Vulnerability management, incident response and remediation
• DevSecOps, CI/CD security, automated security testing or policy-as-code
• TCP/IP, OSI model, routing, VPNs, IAM and encryption

Clearance Requirements

• Active UK SC clearance is required as a minimum.
• Candidates must also be willing and able to undergo DV clearance due to the nature of the programme and end-client environment.

What We Are Looking For

This role would suit a senior hands-on security engineer, infrastructure security engineer, network security engineer, platform security engineer, cyber security engineer, DevSecOps engineer or security-focused infrastructure specialist.

You will need to be comfortable working onsite in Manchester, operating in a high-security environment and taking responsibility for security across critical systems.

This is not a passive monitoring role. It requires someone who can own, improve and shape security across a critical platform while remaining close to the technology.
