1d•$111,000 - $160,000•Hybrid

About The Position

This role sits within the Finance team and requires a combination of finance and systems expertise related to financial applications. It is not an IT role. Composites One seeks a Sr. Financial Systems Analyst to own and advance our enterprise performance management stack, with primary focus on OneStream for consolidation, planning, and reporting. This role also supports SAP ERP finance metadata, processes, and testing, and contributes to evolving reporting and advanced analytics. You will partner with Accounting, Finance, and IT to deliver U.S. GAAP-compliant reporting while ensuring system stability, data integrity, and timely issue resolution. As the OneStream subject-matter expert, you will lead configuration, development, integrations, and reporting architecture within our governance framework. You’ll ensure the platform supports budgeting, forecasting, and monthly close while maintaining performance, scalability, and security. The ideal candidate combines hands-on OneStream expertise with real finance experience (close, consolidation, budgeting, and reporting) grounded in U.S. GAAP, and is eager to advance finance process maturity at Composites One.
