• Reviewing and correcting engineering studies while developing solutions to avoid future issues
• Developing technical scopes of work and supporting contract execution
• Partnering closely with project managers to support projects from early development through completion
• Influencing multi‑disciplinary engineering teams and providing technical direction
• Managing engineering milestones, identifying technical risks, and supporting mitigation strategies
