We are a fast-growing global FinTech company, operating across multiple regions with a footprint spanning trading floors, data centres, and corporate offices worldwide.

This is a hands-on, high-impact role. You'll be the subject matter expert who turns business requirements into reliable, secure, and scalable network solutions, from greenfield office buildouts to major refits of existing sites.

Network Design & Standards

• Define and track network SLAs and KPIs for office environments, with regular reporting to IT leadership

• Champion a user-first approach to network performance, proactively identifying and resolving degradation before it generates tickets

• Drive continuous improvement initiatives based on monitoring data, user feedback, and post-incident reviews

Office Buildouts & Refits

• Lead end-to-end network delivery for new office openings and major refits globally from initial scoping and design through to commissioning and handover

• Engage and manage third-party vendors, cabling contractors, and ISPs to ensure on-time, on-budget delivery

• Conduct site surveys and produce detailed network designs, rack layouts, and cabling schematics

• Ensure all office network deployments adhere to global architecture standards and security requirements.

• Produce high- and low-level network design documentation for office network deployments.

Stakeholder & Project Management

• Partner with Real Estate, Workplace, GTSO Teams and senior IT leadership to plan and scope network requirements for new and changing office locations

• Produce clear technical documentation and present designs to both technical and non-technical stakeholders

• Manage project timelines, risks, and dependencies across concurrent office programmes

Required Skills & Experience

• 8+ years of hands-on network engineering experience, with a strong focus on corporate office environments

• Expertise in Cisco and/or Juniper switching and routing (BGP, OSPF, VLAN design, QoS)
