Are you a seasoned accounting professional with a passion for precision, process improvement, and operational impact? Do you thrive in environments where compliance meets creativity — and where even part-time work can make a major difference?

Blackmere's is seeking a Part-Time Senior Accountant & Operations Support Specialist to take the reins of their accounting function and bridge the gap between finance and operations. This isn’t your typical back-office role — it’s a high-impact opportunity for someone who can think strategically, act independently, and partner closely with leadership to drive business continuity and compliance in a fast-paced environment.

This role is ideal for professionals experienced in government contracting, project-based workflows, and technical services. If you’re looking to bring your accounting expertise to a flexible, remote-first role with meaningful responsibility and minimal red tape, this could be the perfect match.

What You’ll Be Doing

As the financial and operational backbone of the business, you’ll oversee everything from invoicing and payroll to contract lifecycle tracking and compliance support. You’ll manage recurring tasks with clockwork accuracy, while also improving systems, strengthening documentation, and serving as a trusted advisor on financial and contractual matters.

Your key focus areas will include:

Invoicing & Accounts Receivable

• Own the biweekly invoicing cycle, including specialized formats for national laboratories.
• Ensure invoices match contract terms, billable rates, and required documentation.
• Track aging, follow up on payments, and manage short-pay adjustments

Contract Tracking & Operational Support

• Maintain and update a centralized contract tracker (rates, POs, LOOs, milestones, etc.)
• Monitor burn rates, renewals, and deliverables, and proactively flag budget thresholds.
• Support operational workflows with clear financial interpretations of contract terms

Government Contracting & Compliance

• Ensure accuracy and timeliness of GSA and federal reporting requirements.
• Track deadlines and maintain compliance documentation for ECC, per diem, and cost rules

Payroll & Multi-State Compliance

• Process hourly and salaried payroll in Gusto across multiple states
• Handle job costing, project-specific rates, and contractor reimbursements
• Coordinate with compliance vendors for state registration or filings

Month-End Close & Reporting

• Manage reconciliations, accruals, amortizations, and adjustments
• Deliver monthly financials and executive summaries with actionable insights

Systems & SOP Optimization

• Strengthen integrations across Harvest, QuickBooks, Gusto, and Zoho Checkout
• Own and update SOPs, spot process gaps, and implement improvements

What You Bring to the Table

Required:

• 5+ years in Senior Accounting, Project Accounting, or hybrid Finance/Ops roles
• Strong background in consulting, recruiting, or government contracting environments
• Expertise with:
• QuickBooks Online
• Gusto
• Harvest

• T&M billing and PO tracking
• Strong communication skills and a proactive, independent work style

Preferred:

• Bachelors degree in accounting or business
• Familiarity with GSA regulations and federal cost standards
• CorpNet or similar platform experience for state compliance

What’s In It for You

• Flexible Remote Work: Set your schedule around key deadlines (biweekly invoicing, payroll, and month-end).
• High Impact in Few Hours: Contribute meaningfully in just 5–10 hours per week.
• Strategic Visibility: Work directly with leadership in a highly collaborative, low-bureaucracy environment.
• Compensation: Competitive hourly rate, based on experience.
