Network Consultant

Contract Senior Network Engineer (Juniper / Campus / NAC)

Location: Newcastle (2 days onsite / 3 remote)

Rate: £500-£550 per day (Outside IR35)

Contract: Initial 6 months

We are looking for a senior, hands-on Network Engineer / Consultant to support the design and delivery of a Juniper-based campus network integrated with HPE Aruba ClearPass NAC across a UK and international estate.

This is not a BAU support role. You’ll be working alongside lead consultants to help get solutions designed, built, and delivered.

The Role

You will be involved in:

• Deploying and supporting Juniper enterprise/campus switching environments
• Working with campus fabric architectures (e.g. EVPN/VXLAN, spine-leaf, or similar)
• Integrating and delivering Aruba ClearPass NAC (802.1X, profiling, enforcement, RADIUS/TACACS)
• Contributing to HLD/LLD, design decisions, and implementation plans
• Supporting delivery across multi-site / international environments
• Troubleshooting complex network issues during rollout and migration phases

Essential Experience

• Strong hands-on experience with Juniper networks (Junos, EX/QFX, campus/enterprise switching)
• Experience delivering NAC solutions, ideally Aruba ClearPass
• Solid understanding of 802.1X, RADIUS, device profiling, policy enforcement
• Experience working on design and build projects, not just operations
• Comfortable working autonomously and contributing at a senior technical level

Desirable (Nice to Have)

• Experience with EVPN/VXLAN or fabric-based architectures
• Exposure to Juniper Mist-managed environments
• Experience in consulting or professional services environments
• Juniper (JNCIS/JNCIP) or Aruba certifications
