  • Serving as the first point of contact for the project office, providing professional customer service to employees, visitors, subcontractors, and clients.
  • Supporting project meetings, correspondence, and office operations.
  • Assisting the project team with administrative needs that contribute to successful project delivery.

Location: Full-time at the jobsite project office or at Sellen's main office, depending on business need and you may move between the sites over the course of tenure.
