About the Role OpenAI is hiring a Senior Manager, Financial Reporting to help build and run a best-in-class financial reporting engine in a technically complex, rapidly evolving, and high-growth environment. We are looking for a seasoned external reporting professional who pairs strong technical judgment with a roll-up-your-sleeves mindset - owning key reporting deliverables, driving rigorous tie-outs and disclosure quality, and converting ambiguity into audit-ready output. This role will collaborate closely with teams across Accounting, FP&A, Tax, Legal, and Investor Relations to improve reporting processes, streamline data flows, and elevate how financial information is communicated across stakeholders. This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees.

Own end-to-end financial statements and disclosures — Prepare GAAP financial statements, footnotes, and supporting schedules; maintain rollforwards, tie-outs, and internal consistency checks to ensure outputs are complete and audit-ready. Drive audit readiness and execution — Partner with external auditors to manage day-to-day audit workflow (PBC coordination, support quality, issue resolution) and keep reporting on track with minimal rework. Lead disciplined close-to-reporting tie-outs — Ensure reporting outputs reconcile to source records, variances are understood/documented, and key schedules are accurate, well-supported, and repeatable each cycle. Partner cross-functionally to deliver high-quality reporting — Collaborate with Accounting, FP&A, Tax, Legal, and Investor Relations to align inputs, resolve questions quickly, and streamline end-to-end reporting processes and data flows. Translate complexity into clear narratives — Turn technical accounting conclusions, analyses, and audit feedback into crisp disclosures, memos, and leadership-ready summaries with strong written and verbal communication. Improve scalability and reduce manual effort — Identify and implement process improvements, standard templates, and control points to simplify workflows, increase automation where possible, and raise the overall quality bar as the company grows. You might thrive in this role if you have: 10+ years of progressive accounting experience (including 4+ in external reporting), with a strong track record owning GAAP financial statements/disclosures in dynamic and high-growth environments (Big 4 and public company experience preferred).
