About The Position

SigmaCorps Solutions, LLC is establishing an Accounting Administrator within the Finance & Contracts pillar. This is a newly created position — not a backfill of an existing vacancy. As the company grows its government-contracting portfolio, the day-to-day transactional accounting work — accounts payable, employee expense administration, purchase coding, and audit-ready recordkeeping — currently carried by the Finance & Contracts Manager requires a dedicated owner. A defining feature of this role is a deliberate, supported ramp. Responsibilities are learned alongside the Finance & Contracts Manager and released gradually, so the incumbent builds both accuracy and confidence in SigmaCorps’ government-contracting cost environment before taking work on independently. The position is designed to grow — from transactional accounting toward broader finance and contracts support as proficiency develops — freeing senior finance capacity for financial management and strategy.

Requirements

Working knowledge of fundamental accounting principles (e.g., accounts payable and general-ledger coding), through education or experience.
Strong attention to detail and a demonstrated discipline for accurate, well-documented work.
Proficiency with Microsoft Excel.
Ability to follow structured procedures and internal controls consistently.
Strong organizational, time-management, and written/verbal communication skills.
Ability to handle sensitive financial information with discretion and confidentiality.
U.S. work authorization required

Nice To Haves

Bachelor’s degree in Accounting (recommended, not required).
Familiarity with government contracting (FAR/DFARS, DCAA), or a strong willingness to learn.
Experience with accounting / AP systems (Procas or comparable).
Experience with expense-management and workflow tools (SAP Concur, Smartsheet, or similar).
Exposure to indirect rate structures and cost-pool concepts.

Responsibilities

Own accounts payable — enter vendor invoices accurately and timely, verify required approvals, apply correct general-ledger and indirect cost-pool coding, and maintain complete AP records.
Administer employee expense reports — review for policy compliance, valid receipts, correct coding, and cost allowability; identify exceptions and route for approval.
Administer the Staff Purchase List workflow — confirm purchases are coded in accordance with the chart of accounts and the Staff Purchase Policy.
Maintain audit-ready documentation — keep supporting files complete, organized, and easy to retrieve.
Support coding and compliance — apply the chart of accounts correctly, follow FAR/DFARS- and DCAA-aligned documentation practices, and support month-end close and audit readiness within scope.
Follow internal controls — adhere to SOPs and policies; flag exceptions, unusual items, and coding questions to the Finance & Contracts Manager.
Coordinate cross-functionally — work with staff and operations personnel on purchase documentation, receipts, and coding questions in a clear, professional manner.
Improve the process — contribute to refining and documenting transactional processes as familiarity grows.
