Overview

We’re hiring a Senior Network Engineer for one of our client with a strong focus on Aruba enterprise wireless deployments, combined with solid experience working in ISP/WISP environments.

This is a hands-on role where you’ll lead wireless implementations, handle complex troubleshooting, and support high-performance network infrastructure.

This is not a pure support role — it’s a mix of project-based work, L3 escalations, and client interaction.

What You’ll Own

Aruba Enterprise Wireless (Core Focus)

• Lead end-to-end Aruba deployments (Controllers, APs, Aruba Central)
• Conduct RF analysis, interpret heatmaps, and optimize coverage
• Design and support high-density wireless environments
• Manage post-deployment performance and troubleshooting

ISP / WISP Infrastructure (Secondary)

• Configure and troubleshoot Mikrotik and Cisco devices (CLI-heavy)
• Manage routing protocols (OSPF, BGP), VLANs, and segmentation
• Support PTP / PTMP wireless links (Cambium, Ubiquiti, etc.)
• Monitor network performance and resolve outages

Must-Haves (Non-Negotiable)

• Strong, hands-on experience with Aruba wireless networks
• Experience working in a WISP / ISP environment
• Solid CLI experience with Mikrotik (RouterOS) and Cisco (IOS/NX-OS)
• Strong understanding of:
• TCP/IP, subnetting, VLANs, QoS
• Routing protocols (OSPF, BGP)

•
• Experience with RF planning and wireless link design (PTP/PTMP)
• Advanced troubleshooting skills (packet capture, spectrum analysis)

Nice to Have

• Aruba certifications (ACMA, ACMP, ACDP)
• Experience with multi-site or large-scale deployments

Role Structure

• Combination of project-based implementation + L3 escalations
• Some client-facing interaction during deployments and issue resolution
• Includes on-call responsibility for network incidents

What Success Looks Like

• Reliable, high-performance Aruba wireless deployments
• Fast and effective resolution of complex network issues
• Stable ISP infrastructure with strong uptime
• Ability to operate independently and own technical outcomes

Interview Process

• Step 1: Pavago Screening (experience, communication, role alignment)
• Step 2: Technical Interview (deep dive into Aruba, networking fundamentals, and real scenarios)
• Step 3: Client Interview (technical + team fit)
• Step 4: Final Discussion / Offer
