Remote Controller Jobs in Somerville, MA (NOW HIRING)

We are looking for a Senior Accountant as part of our corporate team that will support MAS Home Care, MAS Community Health and SPARC Services & Programs.

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 remote role that will work in the East Coast time zone. The target salary for this full-time role is $80,000-$90,000.

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.
