About The Position

Underwater Mechanix Services (UMX) is seeking a highly organized, proactive Construction Administrator to serve as a critical operational partner across our marine construction and commercial dive projects. This is not a passive administrative role. We are looking for someone who understands how construction projects actually move in the field. Keeping documentation, communication, compliance, and coordination aligned before issues impact schedule, cost, or execution are basic competencies expected. You will work directly alongside Project Managers, field leadership, subcontractors, and clients to maintain control of project documentation, contract flow, change management, and project compliance across multiple active projects. Your ability to anticipate needs, maintain accountability, and keep information moving accurately and efficiently will directly impact operational success. UMX performs demanding marine and heavy civil work in complex commercial and federal environments. The right candidate thrives in fast-moving operations, communicates clearly under pressure, and takes pride in building systems that keep projects running smoothly.

Requirements

• Minimum 5 years of experience in construction administration, contract administration, project coordination, or project management support.
• Strong understanding of the construction project lifecycle from preconstruction through close-out.
• Proven ability to manage multiple concurrent projects and shifting priorities in deadline-driven environments.
• Experience working with standard construction contract documents; familiarity with AIA contracts and FAR/DFARS requirements preferred.
• Proficiency with construction management platforms such as Procore, CMiC, Autodesk Construction Cloud, or equivalent systems.
• Strong written and verbal communication skills with the ability to translate complex project information into clear, actionable communication.
• Experience supporting federal, municipal, marine, heavy civil, or industrial construction projects is strongly valued.
• High attention to detail without losing sight of broader project priorities and operational impact.
• You operate with urgency, structure, and ownership.
• You do not wait for problems to surface. You monitor schedules, recognize pressure points early, and help teams stay ahead of issues before they affect execution. You understand that strong project administration is not paperwork for paperwork’s sake — it is a critical part of delivering successful projects safely, efficiently, and professionally.
• You bring calm organization to fast-moving environments, communicate clearly across all levels of a project team, and take pride in being someone others can rely on when projects become demanding.
