Network Implementation Engineer

Role Overview

A major refresh and refurbishment programme is underway across a large corporate campus in London supporting critical, business-sensitive operations.

We're seeking three experienced Network Engineers to support the design, implementation and delivery of campus network changes.

This is a delivery and project-based role, not a support or operational one.

We need engineers used to delivering: planning, preparing and driving project work end-to-end, instructing and coordinating other engineers or contractors, and physically delivering, installing and migrating kit — rather than fixing or maintaining existing infrastructure.

Candidates should be comfortable operating in a highly regulated, large enterprise environment with strict change controls, working alongside cabling design, audio-visual, security, construction and end-user testing teams.

Indicative work split

Implementation ~60%

Design (largely templated and repeatable) ~20%

Project coordination, validation and other tasks ~20%

Programme Scope

Reviewing and relocating main equipment rooms across the building

Refreshing floors as they are decommissioned, refurbished and brought back into service

Migrating services to temporary core/distribution and ultimately to the final core/distribution design

Deploying and configuring new network kit as floors and equipment rooms become available, including delivering kit to site, instructing junior engineers/contractors, and migrating and refreshing existing switches

Refreshing wireless infrastructure across multiple generations of Wi-Fi deployed across the estate, including managing user Wi-Fi through construction and handover phases and coordinating closely with construction teams

Building network infrastructure to the standard expected in live operations, with security requirements designed in from the outset rather than retrofitted

Validating network functionality jointly with cabling, AV, physical security and end-user testing teams

Note: The programme is office/campus focused, with minimal involvement in data centre or load-balancing technologies. Candidates should still have experience deploying data centre-grade network devices, reflecting the calibre of kit and change discipline required.

Technical Requirements

Core — Essential:

Cisco Catalyst switching — 6500, 4500 and 9410 platforms

Cisco wireless access points across multiple generations — 3800 series through to 9130 series

Cisco wireless controllers — 5520, 5508 and 9800 series

Cisco Catalyst Centre and Cisco Prime Infrastructure

Strong, Wi-Fi savvy campus wireless experience — a key differentiator for this programme

Recent, hands-on experience deploying and refreshing network infrastructure in a live campus environment

Experience deploying data centre-grade network devices

Campus edge design experience

Heavy use of BGP and Layer 3 routing domains in a campus context

Supplementary — Desirable:

General awareness of firewalls in a campus context

Basic multicast configuration (e.g., digital signage use cases)

Voice VLAN configuration to switchport level

Delivery & Project Skills

Demonstrable large enterprise experience — this is not a support-led or operational role

A project-based mindset with a track record of implementation work, not BAU support or fault-fixing

Strong project delivery skills — planning, preparing and driving network workstreams end-to-end

Comfortable delivering and physically installing kit, instructing and directing other engineers or contractors, and carrying out switch migrations and refreshes

Ability to guide project managers through logical sequencing of network activity

Proactive in engaging cabling, AV, security, construction and end-user teams to deliver to plan

Comfortable producing and following templated, repeatable designs at scale

Environment & Ways of Working

Candidates must understand the operating norms of a highly regulated environment, particularly strict change control and the consequences of unauthorised actions on production.

Experience in financial services or other highly regulated industries (oil & gas, defence, etc.) is preferred, where candidates can clearly demonstrate equivalent change discipline.

Onsite presence is expected for relevant tasks.

Heavy out-of-hours and weekend work is required to align with campus change windows.

Remote working is possible for activity that does not require physical presence.
