We require an experienced senior network engineer to work collaboratively with a network architect and other senior network engineers to lead the implementation of a strategic migration from our legacy Cisco 6509-based network and associated legacy technology components to a modern Cisco Nexus-based infrastructure. The role is critical to reducing HSE's technical debt, ensuring a seamless transition and improvement to our LAN whilst preparing for a future WAN transformation that will shift our connectivity model from MPLS to internet-prioritized site access.

The successful applicant will work collaboratively to interpret high-level designs and contribute to the production of low-level designs, and crucially, plan and lead the planning and implementation of the changes required to deliver the agreed design. Disruption to customer-facing services must be minimised and some working outside normal business hours will be necessary.

Implementation

Stakeholder Engagement

• Work closely with HSE Technical Operations, Security, Application, and Service Operations teams to understand dependencies and ensure alignment
• Provide technical leadership and guidance throughout the migration lifecycle

Governance and Compliance

• Follow HSE change management processes

Key Deliverables

• Reconfiguration of HSE's core network to route all traffic and VPN connections through the Palo Alto firewalls and Cisco Nexus switches
• Removal and decommissioning of the legacy Cisco 6509 network cores
• Removal and decommissioning of the legacy Cisco ASA firewalls
• Removal and decommissioning of the legacy Forcepoint Sidewinder firewall
• Removal and decommissioning of the legacy Microsoft TMG proxy servers
