About the Role CoreWeave is looking for a Senior Accountant, Financial Close & Reporting to help lead some of the most technically ambitious general ledger work in the market. You will own key areas of the month-end close, maintain the integrity of the balance sheet, operate and scale SOX controls, and translate complex accounting activity into clear, decision-ready insight for Finance and executive leadership. You will join an exceptionally credentialed team drawn from Big 4 practice and public company finance. Our team brings IPO experience and deep SOX fluency, but we are also builders: we design our own automations and deploy agentic AI against work that should not exist. The culture is strategic, collaborative, and genuinely generous, with colleagues who carry real mastery without ever needing to announce it. This role is ideal for an accounting professional who wants meaningful ownership, enjoys solving problems at the source, and is energized by the pace and ambiguity of a high-growth, multi-entity company. What You’ll Do Month-End Reporting & Executive Communication • Own the month-end close for assigned areas, including complex balance sheet reconciliations across prepaids, indirect expense accruals, and capitalized project costs, together with the related SOX controls. • Prepare and present monthly and quarterly analyses, key data, and operating metrics to executive leadership. • Build presentations that explain variances, drivers, and methodology, and speak to the analysis directly in leadership reviews. • Support quarterly and annual financial statements, including the Balance Sheet, Income Statement, and Statement of Cash Flows, while maintaining detailed disclosure support schedules. • Execute high-volume and complex journal entries with precision and complete supporting documentation. SOX Controls Ownership & Audit Readiness • Own and operate key SOX controls across close, account reconciliations, journal entries, accruals, and capitalization processes. Perform the control, evidence it, and stand behind its operation. • Produce workpapers, reconciliations, and memos that meet public company standards, with traceable support, complete review sign-offs, and conclusions that remain clear to a future reviewer. • Prepare and review account reconciliations with complete populations, independently sourced support, clear identification of aged or unexplained items, and documented resolution of reconciling items. • Draft and maintain process narratives, flowcharts, and Risk Control Matrices as systems, entities, and volumes change. • Lead process walkthroughs with the SOX program team, internal audit, and external auditors; explain processes end to end, articulate where risk sits, and demonstrate how controls address it. • Manage SOX and audit requests from start to finish, including population completeness and accuracy support, sample selections, PBC schedules, and substantive testing requests. • Investigate control exceptions and deficiencies, assess root cause and severity, design remediation, and implement sustainable improvements. • Partner on control design as entity count, transaction volume, and system complexity grow, including controls over automated and AI-assisted processes. Automation, Agentic AI & Systems Scaling • Serve as the operational lead for close activities in FloQast, NetSuite, and related systems; enforce cut-off procedures and continuously compress the close timeline. • Partner with technology and systems teams to identify, pilot, and deploy automation and AI-enabled solutions across reconciliations, recurring analyses, exception triage, flux commentary, and evidence gathering. • Define practical guardrails, validation steps, and review points that make AI-assisted accounting auditable. • Write and execute test scripts, perform UAT, document defects, and drive fixes and enhancements through resolution. • Support automated allocation and clearing logic within NetSuite or comparable ERP systems, as well as subledger and supporting solutions that improve accuracy at the source. Hands-On Technical Ownership • Take direct ownership of technical accounting research and follow-up items from initial issue through documented conclusion. • Own balance sheet integrity by reconciling monthly, investigating discrepancies, tracing issues to their sources, fixing root causes, and implementing controls to prevent recurrence. • Provide accounting expertise and operational support for system implementations, process redesigns, and other special projects. Cross-Functional Partnership • Partner with FP&A, departmental leaders, and Procurement to improve forecasting accuracy, budget management, and spend visibility. • Support purchase requisition and PO review, accrual estimates, and commitment tracking to ensure spend is captured in the correct period, entity, and cost center. • Work closely with the SOX program team, internal audit, and external auditors as a credible, responsive counterpart who anticipates requests and prepares the underlying evidence. • Translate complex accounting mechanics into clear commentary for senior Accounting and Finance leadership. • Direct and collaborate with offshore and outsourced accounting teams, setting clear expectations and reviewing deliverables with a critical eye. Who You Are • Bachelor’s degree in Accounting, Economics, or a related business discipli
