Role Overview
The L2 Network Support Engineer is responsible for the day-to-day operations,
troubleshooting, and optimization of the data center's network infrastructure. This role
focuses on maintaining the high-speed switching fabric, edge routing, firewalls, and load
balancers that power the cloud region, while also managing local physical network
connectivity.
Key Responsibilities
L2 Network Operations & Troubleshooting (Core L2)
Routing & Switching Support: Configure, maintain, and troubleshoot Layer 2 and
Layer 3 environments (VLANs, Link Aggregation/vPC, OSPF, BGP, and VXLAN
fabrics).
Data Center Fabric Management: Support spine-and-leaf network architectures
(such as Cisco Nexus/NX-OS or Arista EOS) integrated with Microsoft Azure physical
underlay networks.
Security & Edge Support: Maintain and troubleshoot firewall rules, NAT
configurations, and VPN tunnels (IPsec/SSL) on enterprise platforms (e.g., Palo Alto,
Fortinet).
Network Performance Monitoring: Leverage network management tools (SNMP,
Wireshark, NetFlow) to analyze traffic patterns, isolate latency issues, and resolve
packet loss.
Change Management: Implement scheduled network changes, firmware upgrades,
and configuration rollbacks during approved maintenance windows.
Hands-on Essential Support
Patching & Interconnects: Perform physical cross-connects between customer
cages, carrier Meet-Me-Rooms (MMRs), and Microsoft network distribution areas.
Fiber Optic Testing: Use Optical Time-Domain Reflectometers (OTDRs) and light
source/power meters to test, clean, and validate fiber runs and optical transceivers
(SFP+, QSFP).
Device Rack & Power: Physically mount routers, switches, console servers, and
firewalls; connect them to Intelligent Power Distribution Units (iPDUs).
Inventory Control: Conduct routine auditing of network consumables (transceivers,
fiber patch cables, copper patch cords, and rack-mounting kits).
- Exposure to datacentres.
- Cabling and rack stacking
- Decommissioning and labelling
- Hardware troubleshooting
- Server knowledge and hands-on experience.
- Experience working with different types of hardware.
Required Skills & Qualifications
Experience: 3–5 years of experience in network engineering, with a focus on data
center scale networks.
Technical Certifications (Preferred): Cisco CCNP Enterprise / Data Center, Juniper
JNCIP-ENT, or equivalent.
Technical Competency: Strong understanding of the TCP/IP suite, DNS, DHCP,
and structured cabling standards (TIA/EIA-568).
Local Compliance: Clean background record to meet strict physical security access
protocols for UAE-based hyperscale facilities.
Common Competencies for Both Roles (Microsoft DC UAE)
Because these engineers will represent your services within a critical Microsoft site, both
profiles should share the following standard expectations:
SLA/KPI Discipline: Absolute commitment to meeting strict Key Performance
Indicators (KPIs) and Mean Time to Resolve (MTTR) metrics.
Shift Work Readiness: Ability to support 24x7x365 rotational shift schedules,
including weekends and public holidays.
Communication: High proficiency in English (both written and verbal) to document
incidents clearly in ticketing systems (like ServiceNow or internal Microsoft systems)
and coordinate with remote L3 engineering teams.
Health & Safety: Compliance with Data Center Environment Health & Safety (EHS)
guidelines, including safe lifting practices (up to 20-25 kg) and electrical safety
procedures.
Pay: AED15,000.00 - AED17,000.00 per month
Experience:
- Data centre: 1 year (Required)
License/Certification:
- UAE License (Required)
Work Location: In person
