Tektora are proud to be partnering with a long-standing client who are looking to strengthen their team with a Senior Network Engineer in the New Year. If you're considering a fresh start in January, this could be the ideal opportunity.

In this role, you'll be at the forefront of delivering secure, high-performance network solutions, with a hands-on focus across F5 and Juniper technologies. You'll contribute to designs, own LLDs/builds, and be a trusted technical authority on critical projects within a highly regulated environment.

What you'll be doing:

• Shaping and delivering network designs (HLD/LLD, configs, standards).
• Building and operating F5 BIG-IP (LTM, ASM; ideally APM, DNS/GTM, AFM).
• Implementing Juniper EX/QFX/SRX/MX with OSPF/BGP, QoS, HA, ZTP and standardised rollouts.
• Applying zero-trust segmentation and identity-aware controls.
• Integrating Infoblox (DDI/IPAM) solutions.
• Executing FAT/SAT, failover/rollback, producing runbooks, and providing 3rd-line support.

What we're looking for:

• A proven Senior Network Engineer with hands-on F5 and Juniper expertise.
• Strong documentation and communication skills.
• Previous experience within enterprise or regulated environments.
• Active and transferable DV clearance (essential).

If you're looking for a new challenge in the New Year and hold the right experience and DV clearance, we'd love to hear from you.
