Job description

Perimeter Network Engineer – Foundational Platforms

About This Role

Network Engineering is a global organization within the Platform Infrastructure business unit. We engineer technologies, products and solutions across the entire network. This includes networks hosting critical market data, exchange connectivity and e-commerce services, cloud connectivity, the global core backbone, and the design of the physical network supporting campus based users. We are also involved in the development of software solutions to support all aspects of network automation. The team ensures that knowledge, best practices and expertise are shared between regions promoting teamwork and collaboration. We are seeking several experienced engineers with excellent technical, analytical and communication skills.

Project Scope

Asia Cloud-Onramp The Perimeter OnRamp network aims to establish a versatile service provider network that links the DMZ infrastructure in the main data centres to cloud and other third‑party networks in colo sites. By establishing carrier connectivity between our main data centres and the colo sites, it eliminates the long lead times associated with carriers in the cloud provisioning process. This initiative is designed to shorten the time required to provision new cloud connections, whether to boost capacity for existing cloud providers or to establish connectivity with new ones. This project is centered on developing our cloud‑onramp infrastructure within the Asia Region.

Daily activities and responsibilities include:

• Network Infrastructure Design and Planning – Develop detailed technical specifications, network topology diagrams and implementation plans for standardized DMZ, Colo and DC deployments.
• Project Execution and Technical Implementation – Coordinate the hands‑on installation with our global data center team. Manage the configuration and deployment of network equipment, including routers, switches, and firewalls. Coordinate with vendors, manage equipment installation through our global data center team, oversee cabling infrastructure, and ensure all implementations follow established change management procedures and minimise business disruption.
• Cross‑Functional Collaboration and Stakeholder Management – Work closely with senior network leads, project managers and team members to ensure project deliverables meet technical and business objectives. Facilitate technical discussions, provide regular project updates, manage expectations and serve as the primary technical contact for your allocated environment build throughout the implementation lifecycle.
• Testing, Validation and Quality Assurance – Execute comprehensive test plans, perform post‑implementation validation and execute rollback procedures when necessary. This includes network performance testing and site resilience testing, ensuring all systems meet SLA requirements before production handover.
• Documentation, Knowledge Transfer and Operational Handoff – Create detailed technical documentation including network diagrams, configuration templates and operational procedures. Conduct knowledge transfer sessions with operations teams ensuring a smooth transition from project implementation to ongoing network operations and maintenance.
