Our client, a well-respected and growing mid-sized law firm with offices across the Tri-State area and Florida, is seeking a Senior Finance Manager to join their leadership team. This is a critical hands-on role reporting directly to the Chief Operating Officer.

This is not a general accounting role.

Essential Responsibilities:

Financial Management & Partnership Accounting

• Oversee all general accounting operations, including general ledger, financial reporting, month-end/year-end close, A/P, A/R, trust/IOLTA accounting, fixed assets, and cash management.
• Manage law firm-specific accounting functions, including client trust accounts, WIP monitoring, fee participation calculations, and distributions to partners.
• Prepare and review monthly, quarterly, and annual financial statements with supporting analysis for firm leadership.
• Ensure full compliance with trust accounting regulations, ethical standards, and all relevant financial reporting requirements.
• Coordinate annual audits and work closely with external auditors and tax advisors.
• Analyze billing realization, collections performance, and key financial metrics to drive strategic insights.

Benefit and Tax Administration

• Oversee 401(k) audits and benefit plan compliance, including preparation of Form 5500s.
• Manage tax filings, including 1099s, sales & use tax, Commercial Rent Tax, PTET, and K-1 distributions to partners.

Leadership & Collaboration

• Lead, mentor, and develop the accounting and finance team.
• Partner closely with Billing, Collections, and Operations to improve processes, collections, and overall financial performance.
• Support budgeting, forecasting, and strategic financial planning initiatives.

Systems & Process Improvement

• Optimize financial systems and reporting tools to increase efficiency and visibility for leadership.

Qualifications (Required):

• Bachelor’s degree in Accounting or Finance required; CPA strongly preferred .
• Minimum 7+ years of progressive accounting/finance experience , with at least 4+ years specifically in a law firm or professional services environment (this is a hard requirement).
• Strong expertise in law firm partnership accounting, trust/IOLTA accounting, and professional services financial operations.
• Prior management or supervisory experience required.
• Advanced proficiency in Microsoft Excel and experience with legal-specific accounting systems (Elite, Aderant, SurePoint, or similar) is highly preferred.
• Excellent leadership, communication, and analytical skills with a collaborative, solutions-oriented mindset.

This is an outstanding opportunity to join a welcoming, stable, and growing law firm with excellent benefits available from day one.
