Description

Gardiner & Theobald is an independent construction and property consultancy committed to providing world-class service to our clients. Our dedicated team of over 1,300 people delivers Cost Management, Project Management, and Specialist Consultancy services from a network of UK and US offices, united by a common purpose — to build a better tomorrow.

We define our success by the value we create for our clients, the fulfilling careers we build for our people, and our contribution to the communities we work in. Our long-term business performance aligns profit with purpose, taking social and environmental responsibility for our actions, and the legacy we leave behind.

People are central to our mission. We reward individuals based on their unique abilities, talent, and hard work, and we believe in the quality of experiences and in investing in a collaborative culture where everyone can thrive.

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

Working closely with Senior Managers, Associates, Senior Associates, and Partners, you will be responsible for delivering successful project outcomes for our clients. In collaboration with your Project Lead, you will agree your specific roles and responsibilities to allow you to take full ownership of defined project elements. These responsibilities will include, but are not limited to:

Programme Coordination & Delivery

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.

Supplier Engagement & Relationship Management

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.

Client & Stakeholder Management

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.

Professional Development & Continuous Improvement

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.
