Network Engineer

Network & NSX‑T Engineer | Secure / Defence Environments Build, secure and optimise next‑generation network platforms across high‑security environments.

A leading defence organisation is seeking a Network & NSX‑T Engineer with deep technical capability across modern networking, virtualisation and software‑defined architectures. If you thrive in complex, secure environments and enjoy solving real engineering challenges, this role will feel like home.

You’ll be responsible for designing, configuring and supporting advanced network solutions across virtualised and platform environments — including NSX‑T, multi‑vendor physical networking, segmentation, routing and secure connectivity.

Expect hands‑on engineering, problem‑solving, and the chance to influence how mission‑critical networks are built, secured and operated.

• Designing and supporting NSX‑T network virtualisation environments
• Implementing logical switching, routing and micro‑segmentation
• Integrating NSX networking within virtualised platforms (e.g., VCF)
• Working with Cisco or multi‑vendor network equipment
• Configuring routing/switching protocols:
  BGP, OSPF, QoS, VPNs, VLANs
• Applying strong knowledge of TCP/IP and the OSI model
• Implementing firewalls, IDS/IPS, segmentation and secure connectivity
• Using network monitoring, diagnostics and analytics tools
• Supporting delivery within secure, enterprise or defence environments
• Working within ITIL‑aligned service management frameworks

• Strong understanding of modern networking fundamentals
• Hands‑on NSX‑T design, configuration and support
• Experience with software‑defined networking and micro‑segmentation
• Multi‑vendor networking experience (Cisco or equivalent)
• Solid grounding in network security technologies
• Familiarity with virtualisation and cloud networking concepts
• Ability to operate confidently in secure or defence‑grade environments
• Clear communication, problem‑solving and technical ownership

You’ll be shaping secure, scalable, high‑performance networks that underpin critical national capability. Expect technical depth, real responsibility, and the chance to work alongside top‑tier engineers in a mission‑driven environment.

If you’re a network engineer who loves complex challenges, modern tooling and secure‑by‑design delivery, this is a role worth exploring.
