Job description

Sanderson are excited to be supporting a leading secure-sector organisation in the search for a 3rd Line Cloud Network Engineer. This is an excellent opportunity to play a key role within a highly collaborative engineering team, working in a fast-moving environment where reliability, trust, and technical excellence are essential.

Location: Basingstoke - 5 days per week on customer site
Shift pattern: 07:00-15:00 and 11:00-19:00 (weekly rotation)

In this role, you will join a small team of experienced 2nd and 3rd Line engineers, delivering robust network services and supporting a secure, mission-critical environment. You will work through established Service and Change Management processes, monitor systems using Event Management tooling, and respond to incidents through structured triage and escalation.

What you will be doing:

• Responding to escalations from 2nd Line daily checks using ITSM tooling

• Managing PKI certificates for virtual and physical networking devices

• Distributing software, firmware, and security updates across network devices

• Collaborating closely with Design and Engineering teams

• Supporting and maintaining virtual and physical network solutions, providing updates to the Operations Lead

• Completing readiness assessments for new releases entering service

• Producing and maintaining documentation including work instructions and patching schedules

This role requires a DV-cleared, sole-national candidate due to the nature of the environment and customer account. DV Clearance can be sponsored for an individual that holds an active SC, however a start date can only be set on completion of clearance.

Key skills and experience:

• Cloud Administration (eg Broadcom: NSX-T)

Transferable skills and wider experience:

• Firewall Management (eg Cisco Firepower Management Centre)

• Network Devices (eg Cisco IOS, NX-OS & FX-OS/Juniper & JUNOS)

• Network Authentication (eg Cisco ISE)

• Event Management Tooling (eg SolarWinds)

• ITSM tooling and processes

• Cloud Administration awareness (eg Broadcom vCenter - usage rather than administration)
