Senior Service Engineer (L2) – Networks & Connectivity
Cape Town | Permanent | Onsite
Monday–Friday | No nights or weekends
If you’re already a strong 2nd Line Network Engineer and find yourself being the person others turn to when a network issue gets complicated, this could be a strong next step.
Our client is a leading UK technology and managed services provider supporting complex network and connectivity environments for large enterprise customers. Their Cape Town operation works closely with UK teams and customers, providing high-level technical support across routing, switching, firewalls, wireless, WAN, SD-WAN and enterprise connectivity.
This is not a role where you simply escalate difficult tickets.
You’ll sit within a senior Tier 2 function and take ownership of complex network incidents through to resolution — diagnosing where faults actually sit, restoring service, leading technical troubleshooting during major incidents and working directly with carriers, vendors and specialist teams when required.
What you’ll be doing
Own complex L2 network and connectivity incidents from initial escalation through to resolution.
Troubleshoot enterprise LAN/WAN environments across single and multi-site customer networks.
Work hands-on with Cisco, Juniper and Extreme Networks routing and switching technologies.
Support Cisco Meraki switching, security appliances and dashboard environments.
Troubleshoot and implement firewall changes across Fortinet FortiGate, Palo Alto and Cisco platforms.
Diagnose VLAN, trunking, spanning tree, link aggregation and stacking issues.
Troubleshoot routing in live environments, including OSPF and BGP.
Support enterprise wireless environments across Ruckus, Meraki and Extreme Networks.
Investigate connectivity faults across broadband, Ethernet and DIA circuits.
Troubleshoot SD-WAN, including FortiSD-WAN and Meraki environments.
Diagnose site-to-site and remote-access VPNs, NAT and firewall policies.
Use packet capture and analysis to establish exactly where network faults sit.
Troubleshoot core networking protocols including TCP/IP, DNS, DHCP and NAT.
Work directly with carriers and third-party providers to drive incidents through to resolution.
Act as a technical lead during P1 and major incidents, helping restore service while root cause analysis continues.
Identify recurring issues and drive permanent fixes through problem management and RCA.
Mentor and support first-line engineers, helping strengthen technical capability across the wider service desk.
What we’re looking for
You’ll ideally have 5+ years' experience within IT services, network support or an MSP environment, including at least 2 years at second-line level or above.
Most importantly, you need strong hands-on troubleshooting capability. You should be comfortable taking a complex network issue, working through it methodically and owning it rather than simply passing it to another team.
Strong experience across several of the following will be important:
Cisco / Juniper / Extreme Networks
Cisco Meraki
Fortinet FortiGate
Palo Alto
LAN / WAN
Routing & Switching
OSPF / BGP
VLANs / STP / Trunking
SD-WAN
VPN / NAT
Enterprise Wi-Fi
TCP/IP, DNS & DHCP
Packet capture and network analysis
Carrier / ISP connectivity troubleshooting
Experience with MPLS, Juniper Mist, network monitoring, Python, Ansible, load balancing, WAN optimisation or SIP/VoIP would be advantageous.
Certifications such as CCNA/CCNP, Fortinet NSE, Palo Alto PCNSA/PCNSE, JNCIA/JNCIS, CMNA or ITIL 4 would also be beneficial, but practical troubleshooting capability is key.
Why consider it?
This role offers the opportunity to work on complex enterprise network environments without moving into a 24/7 shift pattern.
You’ll have exposure to major customers, multiple networking vendors and challenging incidents where you are trusted to make technical decisions rather than simply follow a script.
The company also offers:
Permanent, full-time employment
37.5-hour working week
Monday–Friday shifts between 07:30 and 18:00 UK time
No nights, weekends or 24/7 cover
Medical package
Funded certifications and professional development
Clear progression into senior and specialist networking roles
Supportive technical team with opportunities to learn from experienced engineers
If you’re a strong L2 Network Engineer, Network Support Engineer or MSP Network Engineer who wants more technical depth, greater ownership and exposure to enterprise environments, I’d be keen to speak with you.
