About the Role

We are currently seeking an ambitious and motivated Project Manager to support the continued growth of the business and the delivery of world-class service to our diverse client base. Working within a dedicated and dynamic team and reporting directly to project leaders, this is an exciting opportunity to work on high-profile infrastructure programmes alongside the best clients, consultants, and contractors in the industry. This role is well suited to a motivated professional who has demonstrated strong project coordination, supplier engagement, performance governance, and stakeholder management skills in a complex operational environment, and who is ready to apply those capabilities within the supply chain workstream of a capital infrastructure programme. The ideal candidate will be one who aims to grow into a leadership position, who thrives on challenge and client-facing responsibility, and who is both eager to learn and develop while actively contributing to G&T's position as a leader in the industry.

Key Responsibilities

• Coordinate all supply chain activities across the project lifecycle, from pre-procurement market engagement and supplier onboarding through to ongoing performance monitoring and contract close-out.
• Develop and maintain project documentation, project delivery schedules, and workstream trackers to provide clear and accurate programme visibility for the wider project team.
• Identify, escalate, and manage supply chain risks and project delivery issues, maintaining a live risk register and implementing mitigation plans to protect programme continuity.
• Liaise with the Procurement team and other stakeholders to progress project plans, ensuring alignment between supply chain activities and broader programme milestones and client objectives.
• Produce timely and accurate programme reports, performance updates, and delivery dashboards for senior stakeholders and project governance forums.
• Support the development of documentation required for various procurement projects and initiatives across the programme.
• Build and maintain strategic relationships with critical suppliers and infrastructure delivery partners, aligning their performance and capacity with programme milestones and client commercial objectives.
• Plan and lead market-sounding exercises, supplier briefings, and engagement events to assess the readiness and capability of the supply market ahead of major infrastructure procurements.
• Develop close, trust-based relationships with the appropriate client representatives and other professional team members, ensuring you are seen as a critical contributor to the success of each project.
• Understand the distinction between outcomes and outputs, taking strategic responsibility for client outcomes - not just deliverable outputs - at every stage of the project.
• Develop confident, clear, and professional communication skills across both written and verbal channels, engaging effectively with internal teams, clients, suppliers, and external stakeholders.
• Proactively develop your knowledge of the project management in a supply chain lifecycle, identifying and addressing gaps to achieve technical excellence in your area of practice.
• Utilise and contribute to the improvement of G&T's best-practice tools, processes, and technology platforms to support consistent, high-quality service delivery.
• Promote knowledge sharing and collaborative learning within your peer group, contributing to a culture of continuous professional development across the team.

Desirable
