Job Description:

Cisco-led all-rounder, London project delivery, up to £75,000

Our client is a well-established network consultancy with a strong Cisco heritage and a growing multi-vendor practice. They’re looking for a Network Consultant to join the delivery team — someone who can hit the ground running on enterprise projects, represent the business confidently on customer sites, and work across a broad stack without needing hand-holding.

Cisco is the primary vendor but this isn’t a one-platform role. Aruba, Palo Alto, and Fortinet all feature regularly. Design, delivery, wireless, firewalls, infrastructure — you need to be comfortable across all of it. London-accessible is key; the majority of project work is in and around the capital.

WHAT YOU’LL BE DOING

  • Lead and deliver enterprise network projects across a multi-vendor environment — LLD through to full implementation (80% of the role)
  • Produce Low-Level Designs across routing, switching, wireless, and firewall disciplines
  • Represent the business on customer sites — professional, confident, and technically credible
  • Support pre-sales engagements — scoping, technical input, and customer conversations (10%)
  • Act as SME escalation point and participate in a low-volume on-call rota — 1 in 5 rotation, paid additionally (10%)

TECH STACK

  • Cisco Routing & Switching (primary)

WHAT WE’RE LOOKING FOR

  • Strong Cisco delivery background — routing, switching, and wireless in enterprise project environments
  • Comfortable across multi-vendor environments — Aruba, Palo Alto, and Fortinet experience alongside Cisco
  • All-rounder — wireless, firewalls, and infrastructure projects all in your wheelhouse
  • LLD production capability — you’ve designed and delivered, not just supported
  • Excellent customer-facing skills — you can represent the business on site without supervision
  • Commutable to London within 1.5 hours — the majority of project work is London-based
  • Can hit the ground running from day one — no lengthy onboarding required

THE PACKAGE

  • £70,000 – £80,000 base salary depending on experience
  • ~£2,000 annual bonus — 60% personal performance, 40% company performance, paid quarterly
  • Hybrid working — London project travel is the priority, with occasional South Coast office days
  • On-call: 1 in 5 rotation, low call volume, paid additionally
  • Overtime paid or TOIL at your choice
  • 25 days holiday rising with tenure
  • EV scheme available | Mileage and hotels claimable for travel over 60 miles from office

WHY THIS ROLE STANDS OUT

  • Up to £80k for the right person — London-accessible candidates with strong delivery experience will be at the top of the range
  • Genuine all-rounder role — Cisco core, Aruba, Palo Alto, and Fortinet all in play
  • 80% design and delivery — proper project engineering, not a support queue
  • On-call is low volume and well-compensated — 1 in 5 with additional pay
  • Quarterly bonus instalments — you see the reward regularly, not once a year
  • Multi-vendor exposure that keeps your CV sharp and your skills broad
