Partner with project teams by supporting job costing, customer billing, project accounting, WIP reporting, and cost tracking to help drive successful project outcomes. Contribute to our ERP transformation by learning new systems, adapting to evolving processes, and helping the accounting team successfully navigate our enterprise system implementation. Drive operational excellence by identifying process improvements, collaborating across departments, and providing dependable support wherever it’s needed most.

A collaborative team player who builds strong relationships across Accounting, Operations, and Project Management. A dependable, proactive problem solver who takes ownership and follows through. Someone who communicates clearly and contributes positively to the team’s success. You’re Motivated By… Building expertise across the full accounting cycle rather than specializing in just one area.
