Network Engineer / Crypto Custodian – UK Defence

Location: Corsham, Wiltshire – Hybrid

Salary: £40,000–£45,000 depending on experience plus an excellent benefits package and a yearly TAX FREE BONUS

Security Clearance: SC or DV Clearance required – level dependent on assignment

Our client, operating within the UK Defence sector, is looking for a Network Engineer with previous Crypto Custodian experience to join its team based predominantly in Corsham.

This opportunity would particularly suit a Service Leaver or Veteran from a Royal Signals background, potentially at Corporal or Sergeant level, who has gained practical networking and CIS experience alongside responsibility for cryptographic material and secure communications.

The role combines hands-on network support and engineering responsibilities with Crypto Custodian duties, making it an excellent opportunity for someone looking to transfer their military communications, networking and crypto experience into a civilian Defence environment.

Key Responsibilities:

• Provide day-to-day network engineering and technical support within a secure Defence environment.
• Support the operation, maintenance and troubleshooting of network infrastructure and associated systems.
• Assist with network configuration, connectivity and fault resolution.
• Undertake Crypto Custodian responsibilities and maintain appropriate control and accountability of cryptographic material.
• Manage the receipt, issue, storage and accounting of cryptographic material and associated equipment.
• Maintain accurate crypto registers, records and audit trails.
• Conduct regular checks and inventories to ensure controlled material and equipment is fully accounted for.
• Ensure cryptographic material is handled, stored and distributed in accordance with relevant security procedures.
• Support the secure management of cryptographic keys and secure communications equipment.
• Assist with security audits, inspections and assurance activities.
• Work closely with network, infrastructure, security and wider technical teams.
• Ensure all work is undertaken in accordance with Defence security policies and procedures.

Experience Required:

We are particularly interested in candidates with:

• Previous experience within a Network Engineer, Network Support, CIS, Communications or similar technical role.
• Previous experience undertaking Crypto Custodian or Deputy Crypto Custodian responsibilities.
• Hands-on experience managing or handling cryptographic material, keys or associated secure communications equipment.
• An understanding of network infrastructure and troubleshooting.
• Experience working with secure communications or CIS systems.
• Experience maintaining accurate records and accountability for controlled or classified assets.
• A good understanding of security procedures within a Defence or similarly secure environment.
• Strong attention to detail and the ability to work within clearly defined security processes.

Military Background:

• This position could be particularly well suited to an ex-Royal Signals Corporal or Sergeant who has worked within networking, CIS or communications and has undertaken Crypto Custodian duties during their military career.

• Candidates from Royal Navy CIS, RAF communications or other UK Armed Forces communications and networking backgrounds with the relevant crypto experience are also encouraged to apply.

• Crypto Custodian may not have been your primary military role. If you have worked as a Network Engineer, CIS specialist or communications professional and held Crypto Custodian responsibilities as part of your wider duties, we would be particularly interested in speaking with you.

The Opportunity:

This is an excellent opportunity for a Service Leaver or Veteran to transfer specialist military networking, CIS and cryptographic experience into a civilian career within the UK Defence sector.

If you have a background in military networking or secure communications combined with hands-on Crypto Custodian experience, we would be interested in hearing from you.

The package includes:

• Salary of up to £45,000, depending on experience.
• £3,600 annual tax-free bonus.
• Hybrid working, with two to three days per week in Trowbridge.
• Private healthcare.
• Life assurance.
• Income protection.
• 25 days’ annual leave.
• Excellent additional company benefits.
