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
