Job description

London | Hybrid (3 Days in Office) | £80,000 + Benefits

We're recruiting for one of the UK's largest privately owned Managed Service Providers, delivering complex network and security solutions to enterprise customers across the UK.

They're looking for a technically strong Network & Security Delivery Team Leader to take ownership of major customer projects whilst providing technical leadership to a small team of experienced consultants.

This is predominantly a hands-on technical role, with approximately 80% focused on project delivery and 20% on team leadership. You don't need previous management experience, but you do need the technical expertise to lead complex network and security projects from initial design through to implementation.

Why Apply:

• Technical ownership – Lead enterprise network and security projects from initial workshops and solution design through to deployment and commissioning.
• Cisco & Fortinet focus – Work extensively with enterprise networking, SD-WAN and next-generation firewall technologies.
• Leadership opportunity – Provide technical guidance to 5–6 experienced consultants, with the opportunity to develop your management skills.
• Major customer projects – Deliver complex solutions across enterprise environments, working closely with project management and technical delivery teams.
• Flexible location – Based from any UK office, with hybrid working (3 days in the office).
• Excellent benefits – 25 days' holiday rising to 28, private medical insurance, discounted health plans, virtual GP, wellbeing support and ongoing development through the Wavenet Academy.

What we're looking for:

• Extensive experience designing and delivering enterprise networking and security solutions, ideally within an MSP, ISP or Systems Integrator.
• Strong hands-on expertise across Cisco and Fortinet, particularly routing, switching, SD-WAN and next-generation firewalls.
• Proven experience taking technical ownership of customer projects, including solution design, LLDs, implementation and commissioning.
• The technical depth to act as the senior escalation point and provide guidance to experienced network consultants.
• Cisco and/or Fortinet professional certifications, ideally CCNP and NSE 7/FCSS level or equivalent. Expired certifications can be considered.
• Current or previous SC clearance, with the ability to obtain clearance again.
• A full UK driving licence and willingness to attend customer sites when required.

Previous people management experience is not essential. We're equally interested in senior Network Engineers, Network & Security Consultants, Technical Leads and Network Architects who want to take their first step into leadership without moving away from hands‑on technical delivery.

If you're technically strong across Cisco and Fortinet and want greater ownership of enterprise projects, alongside the opportunity to develop your leadership experience, we'd be interested in speaking with you.
