- Familiarity with EMC cabinets, rack layouts, ventilation, gland plates and cable management.
Ideal Background
We're particularly interested in candidates with experience in:
- BT/Openreach EAD or Carrier Ethernet delivery
- Vodafone Enterprise Access projects
- Utility or power sector telecoms
- Substation communications
- Rail or industrial telecoms
- Fibre access planning and design
Additional Information
- Hybrid role with 3 days per week onsite in Glasgow.
- Candidates should be based in the UK, with local candidates preferred.
- A full UK driving licence is required, as travel to Kirkintilloch, Glasgow will be necessary.
- BPSS clearance is required (SC clearance is not).
