IT Infrastructure Network Engineer
Confirmed on the employer's own hiring board on Oct 13, 2026. First seen by Alion on Sep 23, 2026.
Summary:
Are you a hands-on Network Engineer who thrives on the open road rather than being chained to a desk? Do you love the satisfaction of physical deployments, complex problem-solving, and seeing the direct impact of your work?We are launching a major, high-priority infrastructure overhaul across our remote sites, and we need a skilled engineer to grab their tools, partner up, and lead the charge from the front lines.
Contract Details:
Duration: 12 months fixed term, with potential for extension.
Hours: 37 hours per week, Monday to Friday.
Location & Setup:
This is a field-based role, covering our entire South East geographical area.
You will be part of dynamic, collaborative teams of two.
The Mission: Dual-Project Deployment
You won’t just be maintaining the network; you will be actively transforming it. Working in a team of two, you will hit our various geographical sites to run two critical projects simultaneously:
The NIS Project (Network Security): Install and deploy critical "box" network security hardware to safeguard our infrastructure against modern threats.
The WAN Upgrade: Rip out and upgrade legacy systems to modern Wide Area Network (WAN) infrastructure, preventing critical telephone connectivity drops and ensuring our remote treatment and process sites stay online 24/7.
What A Typical Week Looks Like
This is a highly active, 37-hour-a-week field role where no two days are the same. Your main focus will be out on-site doing the heavy lifting of network engineering:
On-Site Project Execution: Traveling across our regional estate to install, maintain, and decommission physical equipment at data centers and remote processing sites.
Hardware & Cabling: Mounting network cabinets, switches, and routers (yes, you’ll be using power tools!), and implementing new structured cabling solutions (Ethernet, Cat5e, Cat6a, and single/multimode fiber).
Power & Protocol Management: Working hands-on with a mix of 230v AC, as well as 24v and 48v DC power systems used by low-voltage routers, switches, and sensors.
High-Level Support: Backing up the IT Helpdesk by providing expert 2nd and 3rd line support to troubleshoot complex routing, switching, and security issues while on or off-site.
What You’ll Bring:
The Technical Foundations: CCNA, CompTIA, or equivalent certification/formal training.
Field Experience: Proven experience with physical network installations, patching, and enclosure mounting.
Protocol Expertise: Solid knowledge of routing, switching, and network security protocols.
Versatility: Comfort working with low-voltage DC power systems and a "security-first" mentality.
Communication Skills: The ability to collaborate closely with your site partner and explain technical solutions clearly to non-technical end-users.
IT Savvy: Experience with Google Workspace/M365, cloud infrastructure (GCP/Azure/AWS), ITIL frameworks, or a background working within the water/utilities sector.
Note: A full driving license and a willingness to travel across our regional sites are absolute essentials for this role.
