Juniper Wi Fi Engineer Tier

Juniper Wi-Fi Engineer

About the role

Our banking client runs one of the largest Juniper Mist wireless estates in financial services, with thousands of branches, ATM lobbies, contact centers, regional offices and corporate campuses and Data Centers. Wi-Fi supports teller and platform workstations, tablet-based account opening, branch IoT, guest access and corporate mobility, all under strict security and regulatory controls.

We're looking for a Juniper Wi-Fi Engineer to design, build and support the bank's Juniper Mist wireless network. You'll turn the wireless design standards into working configurations, deliver changes safely across thousands of sites, and serve as the final technical escalation point for problems the Wi-Fi Operations team can't resolve. You'll also mentor the operations team so fewer issues need you in the first place.

This is a hands-on senior engineering role. You'll spend part of your time on design and build work and part in the data: Mist APIs, packet captures, RADIUS logs and RF analysis.

Key responsibilities

Design and engineering

Design, build and maintain the wireless network for branches, campuses, contact centers and data center sites on Juniper Mist.

Design standard branch Wi-Fi patterns (small, medium, large, flagship branches, ATM lobbies) that can be rolled out repeatably across thousands of sites.

Build and maintain the Mist organization at scale: org/site structure, site groups, WLAN and RF templates, switch templates, labels, policies, and RBAC for operations, engineering and third parties.

Design secure SSID and segmentation strategy (corporate, branch devices, IoT, guest, vendor), including VLANs, WxLAN policies, and integration with the bank's segmentation and zero-trust models.

Design and configure authentication and access control: 802.1X with EAP-TLS, certificate lifecycle, Mist Access Assurance and/or Cisco ISE / Aruba ClearPass, MAC Authentication Bypass (MAB) for headless devices, and NAC policy.

Design tunneling and traffic steering with Mist Edge where needed (guest anchoring, regulatory segregation, data center tunneling).

Design for resilience: AP and switch redundancy, PoE budgets, WAN-down behavior, cloud reachability, and behavior during Mist cloud or RADIUS outages.

Integrate wireless with the wired and WAN layers: Juniper EX switching, Wired Assurance, WAN Assure / Session Smart Routing, SRX, and the bank's SD-WAN.

Contribute to High-Level Designs (HLDs) and produce Low-Level Designs (LLDs), configuration standards, bills of materials and as-built documentation.
