We are looking for a detail-driven Accounting Operations Specialist to support day-to-day accounts payable and purchase order management for a growing manufacturing business. Reporting to the Accounting Manager, you will process accounts payable accurately and on time, generate and manage purchase orders in Microsoft Dynamics 365, keep sub-ledger reconciliations clean, and support month-end and year-end close.

This is a part-time, on-site role of roughly 20-25 hours per week, on a weekday schedule you and the Accounting Manager set together — real flexibility, real ownership, and a direct line of sight into how a regulated manufacturing business runs.

• Generate, issue, and maintain purchase orders in Dynamics 365 — routing approvals, confirming coding, pricing, and vendor terms, and tracking open POs through receipt and closure.
• Process accounts payable end to end: vendor invoice processing, three-way match of invoice to PO and receipt, payment run preparation, and expense coding.
• Reconcile the AP sub-ledger and received-not-invoiced / open PO accruals to the general ledger, and resolve discrepancies promptly.
• Maintain vendor master data, payment terms, PO records, and supporting documentation.
• Ensure POs, approvals, receipts, and documentation, are coordinated with requisitioners and vendors.
• Prepare and post assigned journal entries and complete assigned month-end and year-end close tasks to deadline.
• Perform bank and balance-sheet account reconciliations and compile supporting schedules for monthly, quarterly, and annual reporting.
• Flag payables and open PO commitments that could affect cash flow and escalation to the Accounting Manager.
• Support external audits with audit-ready schedules and documentation, and contribute process improvements that strengthen accuracy and controls.

• Associate's or bachelor's degree in accounting, finance, or business preferred, or equivalent experience.
• Minimum 1–3 years of accounts payable, purchase order or procurement support, or transactional accounting experience.
• Working knowledge of GAAP, internal controls, and month-end / year-end close processes.
• Proficiency with accounting/ERP systems — ideally Microsoft Dynamics 365 — and strong Microsoft Excel skills.
• Experience in life sciences, or regulated manufacturing environment preferred.
• Comfort resolving routine issues independently under daily supervision, and good judgment about when to elevate.
• Strong accuracy, follow-through, and document-control discipline.
• Strong communication, organizational, and cross-functional collaboration skills.
• Ability to work on-site in Wilmington, Massachusetts.

• Part-time, on-site in Wilmington, Massachusetts — approximately 20-25 hours per week on a schedule mutually agreed with the Accounting Manager. Remote or hybrid work is not available.
• Weekday day-shift hours, with flexibility to schedule working days around close and audit deadlines. Occasional additional hours may be requested and are compensated accordingly.
• Primarily office-based; must be able to remain seated for extended periods and perform routine office physical demands.
• Must be able to climb stairs, both up and down, to access office areas, and lift up to 25 lbs.
