The Role:

You’ll own the design and evolution of secure, scalable network architectures for SME and enterprise clients. You’ll lead discovery, create architectures and low-level designs, guide implementation, and provide expert escalation support across routing, switching, wireless, SD-WAN/SASE, remote access, and cloud networking.

Key Responsibilities:

• Translate business and security requirements into network reference architectures and HLD/LLD documentation.
• Design and oversee implementation of LAN/WAN/WLAN, data centre, and cloud connectivity (including Azure) with resilience, performance, and zero-trust principles.
• Lead SD-WAN/SASE designs (e.g., Citrix SD-WAN/Netscaler), VPN/remote access, NAC, segmentation, and privileged access patterns.
• Define and enforce standards for IPAM, routing (OSPF/BGP), QoS, HA/failover, DDoS protection, and WAF/Firewall policy.
• Produce BoMs, implementation plans, and migration runbooks; estimate effort, cost, and delivery risk.
• Mentor engineers and serve as final escalation for complex incidents and performance issues.
• Conduct security reviews and contribute to managed security offerings (firewall/SOC/SIEM).
• Create client-ready diagrams and documentation; hand over to Managed Services with clear SLOs.

Required Experience:

• 7+ years in network engineering or architecture within an MSP or multi-tenant environment.
• Deep knowledge of routing/switching, WLAN, VPN, SD-WAN/SASE, load balancing, and DNS/DHCP/IPAM.
• Hands-on experience with at least two of the following: Palo Alto, Fortinet/Sophos, Citrix Netscaler/SD-WAN, Cisco/Aruba/Mist (AI-driven Wi-Fi desirable).
• Strong Azure networking experience (VNets, vWAN, VPN/ExpressRoute, firewalls, private endpoints).
• Proven track record producing design documentation (HLD/LLD), Visio/diagramming, and engaging stakeholders.
• Familiarity with zero-trust/NAC, PAM, and security frameworks; experience with SIEM/SOC workflows is a plus.
