Job description

Job Title: Interim Project Manager – Network & Infrastructure Refresh

Organisation: Local Government

Location: Hybrid – 2–3 days per week on‑site (London)

Type : Interim / Contract | Immediate Start

Our client is seeking an interim project manager to lead the delivery of its Infrastructure Network Modernisation Programme — a major transformation initiative to enhance digital infrastructure, operational efficiency, and hybrid working capability.

Key Responsibilities

• Manage the phased rollout of a new, cloud‑managed network architecture across all sites, including main offices, libraries, and community hubs.
• Oversee multiple technical workstreams: WLAN, LAN, WAN, and Secure Access Service Edge (SASE).
• Coordinate pilot implementations, vendor management, and wide‑scale deployment of modern Wi‑Fi and network solutions.
• Lead upgrades of end‑of‑life switches and access points, improving security, scalability, and performance (e.g., Wi‑Fi 6 / 6E, PoE++).
• Drive the transition from legacy networks to a distributed, cloud‑first model (Direct Internet Access, SD‑WAN overlay, hybrid remote access).
• Collaborate with Procurement teams on purchasing and supplier engagement.
• Manage change through established Change Advisory Board (CAB) processes, ensuring governance and compliance.
• Proactively manage risk, stakeholder engagement, and operational readiness to ensure smooth delivery and minimal disruption.

Context

The existing environment includes Cisco and Aruba systems, with significant technical debt and single points of failure.

The programme aims to remove these bottlenecks, adopt zero‑trust security principles, and deliver resilient internet access across all sites.

The delivery approach is agile, with multiple parallel workstreams and a focus on communication, change management, and benefits realisation.

Candidate Profile

• Proven experience delivering large‑scale network and infrastructure transformation in complex, multi‑site environments.
• Strong understanding of cloud‑managed architectures, SD‑WAN, SASE, and zero‑trust models.
• Experience delivering infrastructure projects within the public sector, ideally local government.
• Deep knowledge of procurement processes, statutory frameworks, and supplier engagement.
• Strong governance, risk management, and stakeholder communication skills.
• Ability to work collaboratively with Subject Matter Experts (SMEs) and internal teams to deliver solutions on time, within budget, and to required quality standards.
