Interpret, apply, and ensure compliance with all project procurement, commercial, and safety policies.
Develop sourcing strategies for complex, high-value, and high-risk packages, incorporating total cost of ownership principles.
Prepare and oversee the development of bid documents, including RFQs, RFPs, tender packages, scopes of work, bid evaluations, and award recommendations.

Provide guidance, mentorship, and day-to-day support to junior procurement team members as required.
Collaborate closely with engineering, construction, commercial, legal, and finance teams to ensure alignment and successful project outcomes.

What You Will Bring

8+ years of progressive experience supporting large infrastructure, transportation, civil, industrial, or construction projects, with significant experience sourcing, negotiating, and administering construction subcontracts for work packages.

Strong analytical, organizational, and problem-solving skills with exceptional attention to detail.
Demonstrated ability to build and maintain effective relationships with internal stakeholders and external suppliers.
