Jobsite Administrative Assistant

We are seeking a dependable, organized Jobsite Administrative Assistant to support a busy construction project in New Florence, Missouri . This is not a traditional corporate office position—you’ll work directly from the jobsite trailer , supporting Project Management and a large field workforce.

This role is ideal for someone who enjoys staying busy, can keep details organized, and is comfortable communicating with a variety of personalities. A major part of the position will involve timekeeping and payroll coordination for 100+ electricians , so we need someone who is confident enough to follow up, ask questions, and respectfully push back when information is missing or incorrect.

What You’ll Do

• Collect and review daily timesheets from Foremen.
• Enter employee hours accurately into the timekeeping system.
• Work with Foremen and Payroll to research and resolve time or pay discrepancies.
• Maintain accurate jobsite records and administrative documentation.
• Answer and make phone calls related to project coordination.
• Handle interoffice mail and general correspondence.
• Provide day-to-day administrative support to Project Management.
• Follow up with field personnel to obtain missing information and meet deadlines.
• Assist with additional jobsite administrative needs as they arise.

What We’re Looking For

• 2+ years of administrative, accounting support, payroll, timekeeping, or similar experience.
• Construction, skilled trades, industrial, field-service, or similar experience is a plus.
• Proficiency with Microsoft Word, Excel, and Outlook .
• Strong attention to detail and accuracy.
• Ability to prioritize multiple responsibilities in a fast-moving environment.
• Confident and professional communication skills.
• Comfortable interacting with a large field workforce and holding people accountable for required information.
• Team-oriented, adaptable, and willing to jump in where needed.
• Professional, dependable, and able to work independently.

Who Would Do Well Here

We are especially interested in an early- to mid-career administrative professional who enjoys a hands-on work environment. Someone coming from construction, manufacturing, warehouse/distribution, field service, transportation, or another operational environment may transition particularly well.

This is not a corporate-office environment . The right person will be comfortable working onsite around Project Managers, Foremen, and 100+ electricians while maintaining professionalism and organization.
