## Description

Computational Physics, Inc. (CPI) is an employee-owned government contractor with a small, close-working Finance team. We're hiring a Senior Accountant to own payroll, accounts payable and procurement. We're looking for someone who takes ownership of their work and wants room to grow.

**What you'll do**  
•Process semi-monthly multi-state payroll, including new hires, terminations, garnishments, retro adjustments, off-cycle payments and benefit and 401(k)/ESOP remittances  
•Reconcile payroll registers and tax liabilities, and support quarterly and year-end filings and W-2s  
•Review timesheets and labor charging before each payroll  
•Own full-cycle AP: invoice review, three-way match, subcontractor invoices, expense reports, credit card reconciliation, payment runs and 1099s  
•Manage procurement of contract-directed materials, equipment, software and services, from quotes and POs through delivery, receipt and DD 250s  
•Review costs for allowability, allocability and reasonableness under FAR, and make sure contract and task order coding is correct  
•Prepare journal entries, accruals and reconciliations for month-end close, and support DCAA/DCMA audits, indirect rates and incurred cost submissions  
•Keep audit-ready records and desk procedures, and help improve the processes as we grow

**What you bring**  
•Bachelor's in Accounting/Finance, or equivalent experience  
•5+ years of progressive accounting experience, including hands-on multi-state payroll  
•Full-cycle AP experience, including subcontractor invoices, expense reimbursement and 1099s  
•Experience at a government contractor subject to FAR and DCAA requirements  
•Working knowledge of cost allowability, allocability and reasonableness  
•Strong Excel and ERP/payroll system skills  
•Accuracy, ownership and an interest in learning beyond your own area  
•Must be authorized to work in the U.S. without sponsorship

**Nice to have:** CPP or FPC; iSolved, Unanet or Bill.com experience; exposure to indirect rates, incurred cost submissions or contract billing; ESOP experience; CPA or progress toward it.

**Where this role can lead**  
We're building a Finance bench and prefer to promote from within. We view this position as a Controller development track. Once you've mastered payroll, AP and procurement, you'll cross-train in our Billing, AR and General Ledger Senior Accountant role. Over time, working closely with the Controller, you'll come to understand the full accounting and finance function. This is a long-term path, and it suits someone who wants to learn and master the whole function before moving into leadership.
