• Strong communication skills with both internal stakeholders and external vendors.
• Ability to understand business context and turn it into clear, repeatable accounting treatment.

• Comfort operating in a fast-moving, lean environment where systems and processes are still being built.

• Identify repetitive, manual, or error-prone accounting workflows and propose practical ways to improve them using automation, AI tools, better spreadsheet design, workflow software, or ERP configuration.
• Help build and document scalable accounting processes as Panthalassa brings more work in-house.
• Support payment operations, including vendor questions, missing payments, invoice discrepancies, payment timing, and related issue resolution.
• Identify errors, gaps, and inconsistencies in existing processes, then help implement practical fixes.
• Support audit, tax, compliance, and other finance requests as needed.
• Partner with finance and leadership, accounting leadership, and external accounting partners on technical accounting questions, controls, close tasks, and reporting needs.
