We are seeking a Network Engineer with strong enterprise wireless expertise to build, implement, and support campus WiFi solutions across Cisco Wireless LAN Controllers (WLC), Cisco Access Points, and HPE Aruba wireless infrastructure.
This is a hands-on role requiring an experienced technical expert who can independently work with stakeholders (Workplace/Facilities, Security, Network, IAM, Endpoints, Applications, and Service Desk) to gather requirements, develop HLD/LLD, execute deployments and migrations, and provide expert-level troubleshooting and operational support.

Essential Job Functions:

Independently engage business and IT stakeholders to implement and support wireless requirements across offices, campuses, warehouses, and critical environments.
Define and implement wireless outcomes for coverage, performance, capacity, resiliency, roaming, security, and guest/BYOD use cases.
Participate in workshops and produce clear recommendations with options, tradeoffs, risks, and timelines.
Coordinate cross-functional readiness (security policies, device onboarding, NAC integrations, change windows, operational support model).

Build, Implementation & Migration Delivery

Work on enterprise wireless solution for Cisco and Aruba environments including:
- Controller-based and/or distributed wireless designs (as per platform)
- SSID (corporate, guest, IoT), RF design strategy, roaming design
- High availability, redundancy, controller/AP failover, and resilience patterns
Develop High-Level Design (HLD), Low-Level Design (LLD), RF/coverage plans, cutover plans, and runbooks.
Work on:
- WLAN security (WPA2/WPA3 enterprise, 802.1X, PSK where appropriate)
- Authentication/authorization flows (RADIUS, SSO where applicable)
- Network segmentation (VLANs, roles, ACLs), QoS for voice/video
- Monitoring and logging standards (alerts, dashboards, health metrics)
Implement wireless solutions end-to-end across Cisco WLC and Aruba:
- WLAN/SSID configuration, policy profiles, RF profiles, AP groups, templates
- AAA integration (RADIUS), certificate-based auth (EAPTLS), posture/NAC integration where applicable
- Guest access and captive portal design (where in scope)
deployment activities including:
- New site bring-up, AP staging, code upgrades, controller migrations
- Legacy-to-modern WLAN migrations (SSID rationalization, new security standards, WPA3 adoption where appropriate)
Validate designs via pilots, performance testing, and controlled rollouts; ensure smooth transition into operations.

Operations & Expert Troubleshooting (Run)

Provide engineering support for wireless services:
- Roaming issues, intermittent connectivity, authentication failures, performance degradation
- RF interference/coverage challenges, channel/power tuning, high-density tuning
- Controller/AP software defects, compatibility issues with client devices and OS updates
Own incident/problem/change management for wireless and drive:
- Root cause analysis (RCA), corrective actions, and preventative controls
Monitor wireless health and user experience through telemetry, logs, and performance metrics; continually optimize capacity and reliability.

Security, Compliance & Governance

Ensure wireless solutions meet enterprise security standards:
- Strong authentication (802.1X), encryption, and segmentation
Support audits, compliance checks, and security assessments (documented controls and evidence).
Maintain secure operational practices (access controls, patching cadence, vulnerability remediation).

Qualifications:

6 years of enterprise network engineering experience with significant wireless focus.
3-5+ years hands-on experience with Cisco WLC and Cisco Client and HPE Aruba WiFi (both preferred).
Proven ability to manage end-to-end delivery: requirements → design (HLD/LLD) → implementation → operations.
Strong skills in:
- Wireless fundamentals: RF, coverage/capacity planning, roaming, high-density design
- WLAN security: 802.1X, WPA2/WPA3, EAP methods (EAPTLS/PEAP), RADIUS/AAA
- Troubleshooting: packet captures, logs, RF analysis, client interoperability issues
Solid networking fundamentals: VLANs, routing, DHCP, DNS, QoS, multicast basics (where relevant).

Aruba and Cisco specific experience such as:
- Aruba Mobility Controllers / Aruba Central (if applicable)
- Cisco WLC platforms and operational models (legacy and modern controller approaches)
NAC integrations (Cisco Client / ClearPass), guest portal/BYOD onboarding flows.
Automation: templates/APIs, scripting (Python/PowerShell), configuration standardization.
Experience supporting voice/video over WiFi (QoS, fast roaming, latency sensitivity).

Behavioral Competencies

Strong ownership and independence; comfortable driving ambiguous problems to closure.
Excellent stakeholder management and communication skills.
Structured problem-solving with strong RCA discipline.
Documentation-first mindset; produces clear designs and operational procedures.
