• Produce and review HLDs, LLDs, configuration standards, site design packs and technical decision records, and validate Wi-Fi designs covering AP placement, RF coverage, capacity, channel and power strategy, roaming and client density.
• Design, develop, verify, test, document and improve scripts or API-based integrations for network automation, reporting, configuration validation and operational efficiency.
• Define test conditions, acceptance criteria and validation plans, design test cases and scripts, and perform post-implementation validation using RF, client, switch, controller, assurance and monitoring data.
• Ensure LAN/WLAN services integrate with identity services, Cisco ISE, 802.1X, DHCP/DNS, routing, security controls, monitoring, ITSM and site infrastructure, and define configuration baselines, templates, supported device models and firmware recommendations.
• Configure network software, templates and equipment, test platform-specific versions in line with agreed designs and standards, and report test outcomes and improvements to configuration, implementation methods and platform standards.
• Diagnose complex LAN/WLAN faults using structured fault isolation, RF analysis, telemetry, logs, packet captures and vendor TAC engagement, and report the results.
• Monitor service performance against agreed KPIs and service levels, analyse service, assurance and incident data to identify recurring issues, design weaknesses, capacity constraints and firmware defects, and govern implementation and operations partners at technical level.
• Assess release and deployment components and provide input to scheduling, migration, rollback and early-life-support planning, coordinating builds, tests and technical acceptance with testers, component specialists, site teams and suppliers.

• Four-year college or university degree with focus on IT, network engineering, telecommunications, computer science, or an equivalent combination of education and senior-level enterprise network engineering experience.
• Minimum of 7 years of progressive enterprise network engineering experience, including substantial hands-on responsibility for Cisco LAN/WLAN design, implementation, troubleshooting and operational governance in office, campus or large-site environments.
• Minimum of 3–5 years of practical experience with Cisco Meraki and/or Cisco Catalyst LAN/WLAN solutions, including design review, deployment support, performance tuning, incident escalation and lifecycle planning.
• CCNA certification is required.
