Project Management & Delivery

• Lead infrastructure and network projects from scoping through delivery, ensuring quality, cost, and time objectives are met.
• Define technical requirements and translate business needs into deliverable solutions.
• Develop and maintain project documentation including architecture diagrams, risk registers, and deployment guides.
• Manage vendors, suppliers, and third-party contractors to ensure aligned delivery outcomes.
• Apply structured project management methodologies (Agile, Prince2, or hybrid).

Stakeholder Engagement & Collaboration

• Act as a trusted advisor to internal teams and business units, gathering and translating technical requirements into actionable solutions.
• Collaborate closely with IT, Operations, Security, and external partners to ensure seamless integration and delivery.
• Communicate complex technical concepts in clear, non-technical language for diverse audiences.

Operations & Support

• Provide third-line support for network and infrastructure incidents and escalations.
• Monitor system performance and implement improvements to enhance reliability and scalability.
• Maintain detailed documentation of infrastructure, configurations, and changes.
• Participate in an on-call or escalation rota as required.

Qualifications & Experience

Essential:

• 5+ years’ experience in network and infrastructure engineering roles.
