Remote Accountant – Client Billing & Reconciliations

Highmark Healthcare | 5-Month Contract | 100% Remote

Sigma Systems Inc. is seeking an experienced Remote Accountant to support Highmark Healthcare. This is a non-traditional accounting position with a strong focus on client billing, accounts receivable, client-level reconciliations, funding settlements, and financial operations.

Due to the governmental nature of the position, candidates must be U.S. Citizens.

The position is initially a 5-month contract with the potential for full-time conversion if a permanent opportunity becomes available.

Responsibilities

• Manage end-to-end client billing processes, ensuring accuracy, timeliness, and compliance with contractual agreements.
• Perform client-level billing reconciliations and funding settlements, researching and resolving discrepancies.
• Monitor and support Accounts Receivable activities including invoicing, cash application, aging, collections follow-up, credits, rebills, and payment discrepancies.
• Partner with clients and internal teams to investigate and resolve billing, funding, reconciliation, and settlement issues.
• Maintain accurate financial records and ensure transactions are recorded in accordance with GAAP and company policies.
• Prepare and analyze account reconciliations, identify variances, research root causes, and recommend corrective actions.
• Support financial settlement activities and ensure client accounts are accurately reconciled.
• Assist in developing and implementing accounting, billing, and reconciliation workflows within a growing or evolving function.
• Identify opportunities to improve billing accuracy, reconciliation processes, operational efficiency, and scalability.
• Collaborate cross-functionally with Finance, Operations, Billing, Treasury, and client-facing teams to maintain financial and data integrity.
• Support audits by preparing documentation, reconciliations, reports, and explanations as needed.
• Assist with banking, treasury, cash management, and other financial operations as required.

Required Qualifications

• Bachelor's degree in Accounting, Finance, or a related field.
• 3–5+ years of relevant accounting, billing, Accounts Receivable, reconciliation, or financial operations experience.
• Strong understanding of GAAP and financial reporting practices.
• Experience working with billing, Accounts Receivable, account reconciliations, cash application, or financial settlements.
• Ability to analyze financial data, identify discrepancies, research root causes, and resolve issues efficiently.
• Experience developing or improving accounting and operational processes.
• Experience with ERP/accounting platforms such as SAP, Oracle, NetSuite, PeopleSoft, or similar systems.
• Advanced Microsoft Excel skills.
• Strong attention to detail, organization, analytical ability, and problem-solving skills.
• Ability to communicate effectively with clients and cross-functional internal teams.
• Ability to manage multiple priorities in a fast-paced environment.
• U.S. Citizenship required.

Highly Preferred

• Experience working for a healthcare payer, health plan, Third-Party Administrator (TPA), or similar healthcare financial environment.
• Experience supporting self-funded/ASO healthcare clients.
• Hands-on experience with client-level reconciliations and/or financial settlements.
• Experience with client funding reconciliations, billing settlements, payer/client account reconciliation, or similar financial activities.
• Experience with banking, treasury, cash management, or funding operations.

What Makes This Role Different

This is not primarily a traditional general ledger or month-end-close accounting position. The strongest candidates will combine solid accounting fundamentals with hands-on operational experience involving client billing, Accounts Receivable, reconciliations, funding/settlements, and resolution of financial discrepancies.
