• Cash, Investments & Treasury Accounting: Direct timely and accurate domestic and global operating cash reconciliations and corporate investment portfolio accounting (ASC 320 / ASC 820), verifying valuation accuracy, interest accruals, and balance sheet classifications.

• Balance Sheet Governance & Executive Flux Analysis: Safeguard general ledger integrity and chart of accounts hygiene; review complex reconciliations and deliver executive-ready balance sheet and P&L; flux commentaries that effectively articulate core business drivers to leadership.

• Cross-Functional Partnership: Serve as a trusted advisor to Global Network Infrastructure, FP&A; and other business leaders—aligning emerging commercial initiatives with US GAAP standards and supporting key strategic financial decisions.

• Audit Readiness & SOX Compliance: Lead coordination with internal and external audit teams, maintaining an audit-ready posture, championing internal control design, and ensuring timely resolution of technical inquiries.

• Process & Systems Optimization: Champion close acceleration and scalability by identifying automation opportunities, refining NetSuite workflows, and adopting modern controllership tools to eliminate manual spreadsheet dependencies.

What We're Looking For:

• Experience: 8–10+ years of progressive accounting experience in public accounting and/or high-growth public technology companies, including 3+ years of direct people management.

• Education & Credentials: Bachelor’s degree in Accounting, Finance, or a related field; active CPA license preferred.
