We are seeking a mid-senior level Network Engineer to support, operate and evolve our enterprise network environment with a strong focus on SD-WAN, LAN, and WLAN.
Experience with Huawei technologies is preferred but not mandatory as the environment is multi-vendor (including Huawei, H3C and others). Candidates from a Cisco-based background must be comfortable transitioning between vendors and willing to upskill quickly. Beyond technical capability, this role requires a hands-on, service-oriented mindset with a willingness to assist other departments when network-related issues arise and to take ownership of problems through to resolution.
Key Responsibilities:
Network Operations & Support
- Support and maintain SD-WAN, LAN, and WLAN environments across multiple sites.
- Monitor network performance, availability, and stability.
- Troubleshoot complex network issues across Layer 1-7.
- Ensure high availability and resilience of network services.
- Participate in on-call or after-hours support when required
SD-WAN
- Operate and support an SD-WAN environment (training provided where required).
- Troubleshoot WAN performance issues including latency, jitter, packet loss, and path selection.
- Validate traffic steering, failover behavior and policy enforcement.
- Work closely with firewall and security platforms to ensure correct traffic flow
LAN & WLAN
- Support and maintain campus switching environments.
- Manage VLANs, IP addressing, routing, and redundancy mechanisms.
- Support enterprise WLAN environments including RF performance, capacity, and client connectivity.
- Troubleshoot wired and wireless user connectivity issues.
Security & Integration
- Work with firewall platforms to ensure secure and reliable traffic flows.
- Troubleshoot asymmetric routing and policy-related issues.
- Assist with network security best practices and operational controls.
Cross-Department Support
- Assist other departments (systems, voice, applications, end users) when network-related issues impact service
- delivery.
- Act as a technical enabler, not a siloed engineer.
- Provide clear communication during incidents and troubleshooting.
- Maintain a “willing to assist” attitude, even when issues fall slightly outside strict job boundaries.
Documentation & Change Management
- Maintain accurate network documentation and diagrams.
- Participate in change planning, risk assessment, and post-change validation.
- Contribute to operational standards and improvement initiatives.
