Accounting Manager

Accounting Manager

Company: Magnus Medical Inc

Location: Burlingame, CA (Hybrid, CA)

Reports to: Director of Accounting

Team: Finance & Accounting

The Role

You'll own the full accounting cycle, from AP and expense coding to billing, collections, and commission accounting, reconciliations, and the month-end close. As we bring accounting in-house, you'll take over work currently handled by Outsourced Accounting , working with the Director of Accounting to transition it without disrupting the close. You'll also be the Director's right hand on our systems modernization: migrating to a new ERP and consolidating Bill.com, Expensify, and Brex onto Ramp. The Director sets the strategy and owns the projects. You'll handle hands-on execution, keep the close running through the changes, and help the team adopt new processes and tools.
