The role supports the general ledger, accounts payable, accounts receivable, payroll accounting, project accounting, reconciliations, and timely month-end/year-end close. This individual will also support the transition from QuickBooks Desktop and spreadsheet-based processes to Unanet ERP and collaborate closely with the CFO, finance team, and project managers.
Key Responsibilities
- Maintain general ledger and subsidiary ledgers; prepare, post, and review journal entries, accruals, prepaid expenses, and account reconciliations; investigate and resolve discrepancies.
- Execute monthly, quarterly, and annual close activities, including bank/credit-card reconciliations, balance-sheet schedules, supporting workpapers, and financial statement preparation in accordance with U.S. GAAP.
- Support AP, AR, cash receipts, customer invoicing, collections, and payroll-related accounting; coordinate cutoffs and validate the completeness and accuracy of transactions.
- Maintain contract- and project-level accounting records, including labor distribution, direct costs, subcontractor expenses, unbilled receivables, and revenue recognition appropriate to contract terms.
- Support indirect cost allocations, fringe/overhead/G&A rate calculations, job-cost reporting, and reconciliation of project costs to the general ledger.
- Assist with incurred cost submissions, audit schedules, supporting documentation, and compliance with applicable FAR, DCAA, and contract accounting requirements.
- Partner with payroll, billing, and project management to ensure accurate timesheets, labor charging, billing support, and controlled corrections before invoice submission.
- Help document SOPs, strengthen segregation of duties and approval controls, support budgeting/forecasting, and explain account and project variances.
- Participate in data cleanup, account mapping, testing, reconciliations, and process documentation for the Unanet ERP implementation and post-go-live stabilization.
Required Qualifications
- Bachelor's degree in Accounting, Finance, or a related field, with at least five years of progressive accounting experience, including substantial hands-on general ledger and month-end close responsibility.
- Strong knowledge of U.S. GAAP, account reconciliations, journal entries, accrual accounting, AP/AR, payroll accounting, and financial reporting.
- Experience with project-based accounting and the ability to reconcile transaction-level activity to the general ledger and financial statements.
- Advanced Microsoft Excel skills, including pivot tables, lookups, complex formulas, and reconciliation of large datasets.
- Ability to prioritize multiple deadlines, maintain complete audit trails, resolve issues independently, and communicate clearly with finance and operational stakeholders.
Preferred Qualifications
- Accounting experience with a federal government contractor, including knowledge of FAR, DCAA audit expectations, contract types (T&M, cost-reimbursable, and firm-fixed-price), and direct versus indirect cost treatment.
- Working knowledge of indirect rates, labor distribution, project cost reporting, unbilled receivables, and incurred cost submissions.
- Hands-on Unanet ERP experience, including implementation, migration, or month-end operations; experience with QuickBooks Desktop is beneficial.
- CPA or CPA candidate, or an advanced accounting/finance degree; not required.
- Experience supporting financial audits, internal control improvements, and process automation.
The annual salary range for this position is $90,000-$100,000.
The listed salary range represents a general guideline; however, RiVidium Inc. considers a number of factors when determining base salary offers such as the scope and responsibilities of the position and the candidate's experience, education, skills, and current market conditions.
