· Installation and commissioning of routers, switches, firewalls, servers and telecoms systems

· Day-to-day operation, monitoring, and maintenance of lab environments to ensure reliability and availability

· Working with Linux-based systems for configuration, management, scripting, and troubleshooting

· Network configuration, connectivity testing, and fault-finding across physical and virtual environments

· Preparing, maintaining and adjusting lab setups to support ongoing research activities

· Maintaining accurate documentation of lab configurations, changes, and procedures

· Ensuring the safety of the lab environment and staff, including physical, electrical and RF

Essential Skills & Background

· Experience installing and commissioning network or telecoms equipment

· Practical knowledge of TCP/IP networking fundamentals

· Familiarity with router and switch CLIs and GUIs (e.g. Cisco, Juniper, Nokia)

· Understanding of routing protocols such as MPLS, OSPF or BGP

· Familiarity with Linux (command-line usage, system basics, configuration, and troubleshooting)

· Experience in an infrastructure, networking, telecoms, or lab-based engineering role

· A hands-on, methodical approach to working with both physical and logical infrastructures

· Willingness to learn new technologies and develop deeper expertise over time

· Comfortable working in a lab environment with real hardware

· Ability to maintain technical network diagrams and commissioning procedures using Microsoft Office

Desirable Experience

· Ability to configure IP addressing, VLANs, and basic Layer 2/Layer 3 network settings

· Experience of common IETF network protocols (e.g. SNMP, TACACS+/RADIUS, Syslog, NTP, DHCP, DNS, IPsec, X.509)

· Knowledge of mobile telecoms (e.g. cellular network concepts, mobile cores, RAN fundamentals, or related protocols)

· Experience setting up virtual, containerized or cloud computing environments

· Relevant certifications (e.g. CCNA, Linux certifications)

What’s on Offer

· Hands-on work with real-world enterprise and telecoms infrastructure

· Opportunity to work alongside experienced engineers and researchers

· Training and support to develop and maintain skills in specialist telecoms and lab environments

· Collaborative, engineering-driven culture, with high standards for quality

· Competitive salary and benefits

· Based in Oxfordshire
