  • Performance Management: Set goals, conduct performance reviews, provide regular feedback, and manage the performance of direct reports, recognizing strong performance and addressing performance gaps promptly and constructively.
  • Career Development & Mentoring: Mentor and develop project engineers along the Level I to Level VI progression, establishing individual development plans, supporting training and certification, and building bench strength and succession within the team.
  • Process Improvement: Identify and implement improvements to project engineering workflows (submittal turnaround, RFI / FCR resolution, CWP development, documentation) and capture lessons learned for application across disciplines and future project phases.
  • Additional tasks as delegated by the Construction Manager(s) / Senior Director.
