Job description

Senior Network Engineer - 70k + 6k Car Allowance + 15% Bonus

Hybrid - Home Based + easy travel to London area (2x/month)
Out-of-hours paid at time and a half

We’re working with a long-standing client of ours, a major player in their industry, and they're looking for a proper Senior Network Engineer to join the team. You'll need to have worked on/lead some Network Security projects to be successful in this role.

We're after someone confident, experienced, and ready to step straight into a hands‑on delivery role. This isn't one for a passenger, you'll be expected to lead network projects from day one, support a junior engineer, and take the reins on everything from firewall migrations to hands‑on data centre work.

The role

You’ll be delivering key network projects including firewall migrations (FortiGate‑heavy), SD‑WAN rollouts, and hands‑on switching/routing across a hybrid environment. You’ll be the go‑to engineer for complex technical issues and low‑level designs, collaborating with architects and working independently where needed.

This role has a strong emphasis on being present during the complex work - so proximity to London is essential, and you’ll need to drive for occasional travel between sites not accessible via public transport.

What we’re looking for

• Someone who's personally led and delivered network projects
• Strong experience with FortiGate, BGP, SD‑WAN, and data centre switching
• Confident producing LLDs, doing hands‑on config, migrations, and kit installs
• A proper communicator - able to articulate technical details to peers and stakeholders
• Experience mentoring or supporting junior engineers
• Bonus if you've worked with Meraki or Cisco ACI

We're after someone senior in both title and attitude - someone who doesn't need to defer decisions or escalation for basic sign‑off. You'll need to be the one who takes ownership and gets things done.

The setup

• Hybrid: Home-based with travel to data centres in London (twice a month)
• You must be within a commutable distance to London and have a driving licence
• Out-of-hours work: Around once a week (paid time and a half), mainly for Q4 migration work - dies down early next year, but some out of hours still expected.
• On-call rota: 1 in 6 once you're up to speed

Process

• 2‑stage interview (remote):
  • 30 mins with the Lead Network Engineer (technical/screening)
  • 1 hour with architects (technical deep dive)

You’ll be reporting directly into a hands‑on and highly capable network lead, joining a team that values ownership, initiative, and delivery.
