Founded in 2005 in California and now headquartered in Dubai, MultiBank Group has grown into one of the world’s largest financial derivatives institutions. With 25+ global offices, a paid-up capital of over USD 322 million, and regulation from 17+ financial authorities, we serve over 2 million clients across 100 countries — powering a daily trading volume exceeding US$18 billion.

As we continue expanding globally, our infrastructure must deliver maximum reliability, performance, and security. We’re investing in world-class networking capabilities across all offices — including our Dubai HQ — featuring high-availability core switching, advanced Wi‑Fi coverage, and resilient UPS systems.

Position Overview

We are seeking a Senior Network Engineer to own, manage, and evolve MultiBank Group’s global office network infrastructure. This is a hands‑on, critical role responsible for the ongoing operation, optimization, and monitoring of all network and connectivity systems — including LAN/WAN, Wi‑Fi, UPS, telco links, and backbone infrastructure.

You will be the technical authority for our upgraded Sigma‑designed network, ensuring seamless operations across multiple floors, high‑availability switching, enterprise‑grade wireless coverage, and continuous uptime of core business systems.

Key Responsibilities

• Oversee daily operations of the corporate network across all HQ floors (core, access, Wi‑Fi, and UPS systems).
• Manage Cisco Catalyst Core (C9300X) and Access Switches (C9200L) architecture, ensuring redundancy and optimized traffic flow.
• Maintain Meraki/Cisco wireless infrastructure, ensuring signal coverage as per the -65dBm design heatmap for all critical areas.
• Supervise UPS health and performance (1KVA and 3KVA systems), ensuring full power backup integrity and SNMP alerting.
• Design and implement network topology changes for scalability and performance optimization.

Monitoring & Automation

• Deploy and maintain advanced monitoring systems for network, telco, Wi‑Fi, and UPS components (e.g., SolarWinds, ThousandEyes, or PRTG).
• Establish dashboards for real‑time visibility, alerting, and SLA compliance with telcos and vendors.
• Integrate monitoring into centralized NOC dashboards and automate responses for recurring faults or outages.
• Conduct proactive performance tuning and root cause analysis for latency, jitter, or packet loss incidents.

Connectivity & Vendor Management

• Serve as the primary liaison for telco providers, ensuring redundancy, SLAs, and capacity scaling.
• Track link utilization, carrier failover performance, and manage network contracts and escalations.
• Coordinate with vendors (e.g., Sigma Technologies, Cisco, Fortinet) for upgrades, patches, and issue resolution.

Resilience & Security

• Maintain configuration backups and failover designs for core and distribution layers.
• Collaborate with cybersecurity teams to enforce network segmentation, NAC, and Zero Trust principles.
• Implement and test network DR and failover procedures regularly.
• Enforce change control and documentation standards aligned with PMI‑based project methodology.
• Own the network roadmap — scaling bandwidth, Wi‑Fi coverage, and power backup as business demand grows.
• Conduct quarterly capacity planning and risk reviews.
• Provide training and guidance to junior network engineers and support teams.

Technical Profile

• Required Knowledge and Experience
• 7+ years in enterprise‑level network engineering, ideally within financial or trading environments.
• Expert‑level knowledge of:
• Switching & Routing: Cisco Catalyst 9300/9200 series, OSPF, BGP, VLANs, STP
• Wireless: Cisco Meraki / Catalyst Wi‑Fi 6 solutions and RF optimization
• Network Monitoring: SolarWinds, PRTG, ThousandEyes, Cisco DNA Center
• UPS Monitoring: SNMP, PowerON, or equivalent tools for power telemetry

• Fortinet NSE4+
• Aruba or Meraki Wireless Specialist
• CompTIA Network+ / ITIL Foundation
• Familiarity with project management or service delivery frameworks (PMI, Agile)

• Works effectively across IT, Cybersecurity, and Facilities teams.
• Driven to uphold uptime, resilience, and operational excellence at all times.
