Senior Accountant, Financial Close & Reporting

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.

• 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.

• 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.

• 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.

• 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.

• 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.

• Bachelor’s degree in Accounting, Economics, or a related business discipline.

• 7+ years of progressive accounting experience, including at least 3 years in a complex, multi-entity environment.

• Public company experience with demonstrated ownership of SOX 404 key controls, including control performance, design, documentation, and evidence.

• Hands-on experience with internal audit, SOX program teams, and external auditors through walkthroughs, sample selections, PBC requests, population completeness and accuracy support, and substantive testing.

• Track record identifying control gaps and deficiencies, assessing severity, and designing and implementing remediation that holds.

• Experience building and scaling control environments as transaction volumes, headcount, and entity complexity grow.

• Subject matter depth in operational US GAAP areas that support the general ledger, including:

  • Internal-use software and cloud computing implementation costs under ASC 350-40.

  • Capitalization of project costs and other capitalizable expenditures.

  • Cost allocation methodologies across entities, departments, and cost centers.

  • Accrued liabilities, loss contingencies, and commitments under ASC 450 and ASC 440.

  • Prepaid and deferred cost accounting, including amortization schedules.

  • Research and development and operating expense classification under ASC 730 and ASC 720.

  • Accounting changes and error corrections under ASC 250.

  • Cash flow classification under ASC 230.

• Demonstrated experience drafting financial statement footnotes and managing the last mile of financial reporting.

• Experience running general ledger operations across a multinational footprint while maintaining consistent accounting treatment and close discipline across jurisdictions and statutory requirements.

• Power-user proficiency with NetSuite or a comparable ERP, such as SAP or Oracle, and close management software such as FloQast or BlackLine.

• Experience working with large data populations from a data warehouse or data lake, and manipulating, joining, and validating data directly using SQL, Python, or comparable tools.

• Demonstrated experience automating close processes and improving reconciliations, schedules, and recurring analyses.

• Hands-on use of AI tools such as Claude, Gemini, or ChatGPT to accelerate reconciliation review, variance research, data transformation, and analysis preparation while keeping outputs validated, documented, and audit-ready.

• Proactive, self-directed, and comfortable moving work forward without being asked.

• Clear communicator who can hold a room of cross-functional stakeholders.

• Curious, agile, and energized by the pace and ambiguity of a high-growth company.

• Relentless problem solver who traces discrepancies to the source, fixes root causes, and implements controls to prevent recurrence.

• CPA license or equivalent.

• Big Four public accounting background.
