(Internal Job Level Reference{{:}} Senior Specialist)
Focus Group is a rapidly growing £300m technology services provider, backed by Hg Capital and recently valued at $1bn. Supporting over 30,000 UK businesses, we're investing heavily in top technical talent and we're looking for a Senior Network Specialist to join our Networking & Security team.
The role
This is a hands-on position where you'll take ownership of complex, multi-site network and security projects end to end. Working in a hybrid setup from Shoreham, you'll act as the technical specialist across SD-WAN, SASE, firewalls, and core networking, delivering high-quality solutions for a range of clients.
You'll produce detailed designs and documentation, lead implementations, support delivery teams during key project phases, and work closely with Solution Architects to turn designs into real-world solutions.
