At MAS Medical Staffing, we help nurses and other healthcare professionals find jobs, and help facilities provide excellent care to patients who need it most. This role will also support MAS Home Care, MAS Community Health and SPARC Services & Programs. We're one of the top tech-enabled medical staffing firms in the country, and we want you to be part of our team!

The Role:
We are seeking an experienced and highly organized Senior Accountant to join our lean finance team as a key contributor. Reporting to the Controller, this role owns the full-cycle accounts payable function, treasury operations, balance sheet reconciliations, and journal entry processing. The ideal candidate brings a strong foundation in general accounting, thrives in a multi-entity environment, and is comfortable operating independently with minimal supervision. Experience in healthcare, staffing, or behavioral health is a plus. This is a hybrid role, working out of our Manchester, NH office.

As the Senior Accountant, you will have responsibility for:
Accounts Payable
  • Own end-to-end AP processing, including invoice review, coding, and approval routing in NetSuite across multiple business units.
  • Prepare and execute payment runs — checks, ACH, and wire transfers — ensuring accuracy, timeliness, and proper authorization.
  • Reconcile vendor statements, resolve discrepancies, and manage vendor relationships and escalations.
  • Maintain vendor master files, including W-9 collection, 1099 tracking, and compliance documentation.
  • Manage corporate purchasing card (P-card/Ramp) administration: statement review, coding, and policy enforcement.
  • Support month-end close by ensuring all AP accruals are posted accurately and cutoffs are maintained.
Treasury & Cash Management
  • Monitor daily cash positions across multiple bank accounts; prepare daily/weekly cash availability summaries for the CFO and Controller.
  • Process and reconcile ACH receipts, lockbox deposits, and wire transfers; investigate and resolve missing or misapplied items.
  • Manage banking portal access, payment approvals, and 2FA administration across multi-facility accounts.
  • Assist with cash flow forecasting by providing actual cash position and disbursement data.
General Ledger & Month-End Close
  • Prepare and post monthly journal entries, including accruals, prepaid amortization, fixed asset entries, and intercompany transactions.
  • Own balance sheet reconciliations for assigned accounts (AP, accrued liabilities, prepaids, cash); resolve aged items timely.
  • Assist in the monthly financial close process in NetSuite, including BU/entity tie-outs, transaction review, and period lock procedures.
  • Support the Controller in preparing supporting schedules and variance analysis for management reporting.
Accounts Receivable Support
  • Provide backup support for AR functions, including cash application, aging review, and collections follow-up as needed.
  • Reconcile AR sub-ledger to general ledger; assist with bad debt reserve calculations.
Compliance & Audit Support
  • Ensure AP and disbursement processes comply with company policies, lender covenants, and internal controls.
  • Provide documentation and schedules in support of external audits, tax filings, and lender compliance reporting.
  • Assist with implementation of new policies and procedures (e.g., T&E policy rollout, purchasing card controls).
In this position, you must have:
  • 3–6 years of progressive accounting experience, with demonstrated ownership of AP, general ledger, and reconciliations.
  • Strong working knowledge of GAAP and general accounting principles.
  • Proficiency in NetSuite or a comparable ERP (multi-entity/multi-location experience preferred).
  • Advanced Excel skills (pivot tables, VLOOKUP’s, multi-sheet reconciliation models).
  • Exceptional attention to detail and ability to manage competing priorities under deadline pressure.
  • Self-starter who can operate independently and escalate issues appropriately.
  • Bachelor’s degree in Accounting, Finance, or a related field.
Preferred experience:
  • CPA, CPA candidate, or equivalent coursework strongly preferred.
  • Experience in healthcare, behavioral health, staffing, or a PE-backed company.
  • Familiarity with payroll-related accounting, multi-state operations, or Medicaid billing environments.

Why You’ll Love Working at MAS:
