• Drive AP and expense automation (e.g., OCR invoice capture, automated 3-way match, self-service reporting) to sustain close speed and accuracy as transaction volume scales


• Partner with FP&A and Procurement to drive spend visibility, budget accuracy, and continuous improvement of the source-to-pay process


• Review and mentor junior accountant(s), building a resilient, cross-trained expense accounting function

• Comfortable operating in a multi-entity, multi-currency environment typical of a scaling global SaaS company


• Comfortable owning payment run governance, approval workflow design, and segregation of duties


• Prior experience reviewing or mentoring junior accounting staff


• Treats expense policy compliance as a control, not just a checklist


• Escalates vendor risk early, before it affects payment timing
