Senior Data Center Technician (L2)
One of Europe's fastest-growing AI infrastructure providers is hiring a Senior Data Center Technician (L2) for its Chester site. Before you settle there, you will spend two fully supported months training across AI data centre sites in the UK and Europe - live hyperscale halls, NVIDIA GPU infrastructure, InfiniBand fabrics and large-scale AI deployments.
About the opportunity
This role pairs advanced technical delivery with shift leadership. You will be the primary technical escalation point before incidents reach the Remote Operations Team, leading complex troubleshooting, mentoring junior technicians and holding the operational standard expected in mission-critical AI environments. It is built for someone who wants a long-term career and a route into senior technical, engineering or management positions.
What you will be doing
- Support day-to-day operation of mission-critical AI data centre environments
- Deliver Smart Hands services - server reseats, drive replacements, transceiver swaps, cable replacements, inspections and photographic documentation
- Perform rack and stack deployments, structured copper and fibre cabling, PDU installation and infrastructure commissioning
- Lead deployment of enterprise server infrastructure supporting AI and GPU compute
- Diagnose and resolve hardware, server and networking faults across mission-critical systems
- Support Ethernet and InfiniBand fabric deployments within HPC environments
- Act as the primary technical escalation point during shift operations
- Resolve complex issues involving BMC/IPMI, server hardware, DPUs and InfiniBand networking
- Mentor Junior Data Center Technicians and produce runbooks and Root Cause Analysis reports
- Manage hardware lifecycle activity including RMAs, inventory and asset tracking; keep ITSM/Jira current
