Effective communication and project management skills are essential, as they frequently lead meetings, review technical reports, and provide guidance to both internal teams and external stakeholders. This collaborative environment fosters knowledge sharing and offers opportunities to mentor junior engineers while advancing large-scale environmental initiatives.
