• Experience in contracts administration, procurement, scheduling, and cost tracking.
• Proficiency in project management software (e.g., MS Project) and ERP/PM platforms (e.g., InEight).
• A current White Card, driver's license, and ability to obtain security clearances.

What Will Set You Apart

• Demonstrated problem-solving skills and mature judgment.
• A strong safety focus and knowledge of HSE legislation.
