Our work will be sensitive, secure, 24x7 and on the most up-to-date high density compute stacks available. Shift teams will be setup and operate 24x7 and successful candidates working on shift will be paid a shift premium for the non-standard unsociable shift hours that will be part of that rota.

Any offer of employment is subject to satisfactory BPSS and SC security clearance which requires 5 years continuous UK address history (typically including no periods of 30 consecutive days or more spent outside of the UK) at the point of application.

Key Responsibilities:

• Manage network and firewall security.
• Troubleshoot network connectivity incidents (this includes routing, switching and security).
• Build, configure and maintain network infrastructures as per best practices.
• Identify service improvements to reduce risk and improve stability.
• Producing high quality implementation scripts, test plans and change controls for all network changes.
• Respond to real-time alerts and dashboards for networking resources to detect service-impacting events.
• Perform initial triage and isolation for incidents following established runbooks and procedures.
• Document incidents, actions, and outcomes accurately in the incident management system. Support service delivery and SLA compliance.
• Investigate and resolve incidents escalated from L1.5 Engineers, conducting in-depth analysis of compute, storage, and network issues.
• Develop and refine troubleshooting guides, runbooks, and knowledge base articles.
• Coordinate with engineering, automation, and vendor teams for persistent or complex technical problems.
• Monitor and analyse performance metrics and incident trends, recommending proactive measures for reliability improvements.
• Mentor L1.5 Engineers to support skill development and knowledge sharing.
• Participate in on-call schedules as required.
• Eligibility for UK Government security clearance.

Required Skills:

• Working knowledge of network security including firewall configuration and security policy management.
• Working knowledge of networking protocols and an understanding of EIGRP, BGP, OSPF, and IP multicast.
• Management of LAN/WAN environments including device protocols and communication standards, such as Juniper, Arista or Fortinet.
• Administration of Firewall systems such as FortiGate, Palo Alto, Juniper, and Checkpoint.
• VPN and Remote Access solutions.
• Associate level Network certification (CCNA, JNCIA or equivalent).
• Working knowledge of implementing and supporting large corporate or data center networks preferably in a multi-client, service provider environment.
• Experience in incident management, advanced troubleshooting, and operational best practices.
• Advanced network troubleshooting skills.
• 2+ years of routing protocols (OSPF, BGP).
• Scripting for automation (Python, Bash).
• Familiarity with ITSM, Agile methodologies and tools eg ServiceNow, Jira.

Qualification:
