Description

Job Summary 

SP6 is looking for a Senior Staff Accountant to keep day-to-day accounting accurate and on time across our three entities: SP6, ASCERA and 112Cyber. You'll own accounts payable (AP) and Ramp expense processing, run customer billing and collections, process closed deals, support professional and managed services revenue recognition, and prepare month-end journal entries and balance sheet reconciliations. You'll report to the Assistant Controller and work closely with our US-based accounting team. 

This is an offshore role placed through our staffing partner. You will work on site at the agency's office five (5) days a week. It suits an experienced, detail-driven accountant who works independently, keeps a close calendar, and is comfortable overlapping with US Eastern business hours.
