Role & What’s in it for the applicant and why would they apply?

This is a true 3rd line network role for engineers who are already operating at CCNP level and want to stay technical, relevant, and challenged without being dragged into on‑call rotas or firefighting at antisocial hours.

You’ll be working in a structured, enterprise‑scale environment where networking is taken seriously, standards matter, and escalation actually means escalation. The focus is on deep technical troubleshooting, stability, and continuous improvement across modern WAN and campus networks.

If you’re tired of being the “everything engineer”, want to sharpen your SD‑WAN and enterprise switching skills, and value work‑life balance just as much as technical depth, this one lands nicely.

Responsibilities

• Act as a 3rd line escalation point for complex network incidents and problems.
• Troubleshoot advanced issues across LAN, WAN, and SD‑WAN environments.
• Support and optimise HPE Aruba switching estates.
• Work with Fortinet SD‑WAN and Palo Alto Prisma SD‑WAN platforms.
• Collaborate with design and project teams on network improvements and changes.
• Perform root cause analysis and implement permanent fixes, not just workarounds.
• Maintain high-quality technical documentation and knowledge base articles.
• Support secure network operations within regulated and sensitive environments.

Skills / Must Have

• CCNP-level skills with a current professional‑level certification (essential).
• Strong enterprise networking background (routing & switching).
• Hands‑on experience with HPE Aruba switching.
• SD‑WAN experience (vendor‑agnostic accepted).
• Ability to operate confidently in a 3rd line support capacity.
• Eligible for SC Clearance (or already SC cleared).

Nice to Have

• Working hours: 9am–5pm, Monday to Friday.
• Hybrid working with 3 days per week in the office.
• Choice of office locations:
  • London
  • Belfast
  • Birmingham
  • Sheffield
  • Manchester
  • Bristol
• Training and development support to keep certifications current.
• Stable, well‑run environment with clear technical ownership.
