As our Controller, you’ll own the accuracy, integrity, and scalability of our financial reporting across a growing, multi-site car wash platform. You’ll be responsible for the monthly close, financial statements, revenue and cash accounting, and internal controls—ensuring our numbers are right, our processes are tight, and our systems scale as we grow.

This role is about operational accounting excellence. You’ll partner closely with Operations, FP&A, and IT to ensure site-level results roll up cleanly, memberships and cash are properly accounted for, and leadership can trust the numbers they’re using to run the business.

If you thrive in high-volume environments, love building disciplined close processes, and want to be the owner of financial truth, this is your lane.

· Are experienced with high-volume revenue, cash reconciliation, and POS-driven businesses.

· Are comfortable owning internal controls, audit support, and lender reporting.

· Are organized, deadline-driven, and passionate about building scalable, repeatable accounting processes.

· Can partner effectively with non-finance teams while maintaining accounting rigor.

· This description is not intended to be an exhaustive list of all responsibilities, duties, or skills required. Duties and 

  responsibilities may change at any time, with or without notice.

· Reviewed balance sheet reconciliations and resolved discrepancies before close.

· Partnered with Operations and IT to troubleshoot data flow issues between POS systems and the general ledger.

· Prepared financial reporting packages for the CFO, senior leadership, and external stakeholders.

· Supported audit, lender, or investor requests with clean documentation and schedules.

· Identified opportunities to automate reconciliations, streamline journal entries, and improve close efficiency.
