- Excellent ability to coordinate multi-disciplinary teams and manage external service providers
- Strong technical writing and communication skills, with the ability to translate complex engineering concepts into actionable project plans
- Demonstrated ability to drive safety culture, particularly in high-hazard decommissioning environments
