• Lead the resolution of contractual issues, drawing on expertise in construction law, NEC contract management and multi‑disciplinary stakeholder engagement.
• Maintain full compliance with commercial, legal, health & safety and regulatory frameworks, particularly those governing major construction and infrastructure works.

Team Leadership & Development

• Lead and develop a cross-functional commercial team supporting construction delivery, including UKIFS colleagues and representatives from Whole Plant Partner organisations.
• Stay abreast of advancements in construction delivery models, digital construction, modern methods of construction (MMC), and large‑scale infrastructure contracting—and embed these insights into programme strategy.
• Promote a collaborative, high‑performance culture across commercial, engineering and construction management teams to support seamless delivery.
• Mentor and coach team members on complex construction commercial matters, NEC processes and supplier performance management.
• Drive continuous improvement initiatives to enhance commercial processes, supply chain performance and the effectiveness of contract governance.
• Maintain strong relationships with contractors and suppliers across the construction supply chain, ensuring accountability and alignment to scope, budget and schedule.

Collaboration & Stakeholder Engagement

• Act as the principal point of contact for all contract‑related matters within your IPT, particularly relating to construction and infrastructure delivery.
• Work closely with engineering, project management, construction management and commercial teams to drive contract performance and resolve issues rapidly.
• Provide training and support to internal teams on NEC procedures, construction contract management and best practices in major project delivery.
• Serve as a cultural ambassador for UKIFS, ensuring our values are reflected in all supplier interactions, negotiations and construction partnerships.
