Preference for candidates with direct experience with advertiser/customer incentive arrangements, multi-currency billing, global invoicing/localization, or multi-entity revenue accounting. - Proven ability to build 0-to-1 finance processes, then harden them into scalable close procedures, reconciliations, controls, and audit-ready evidence. - Strong data fluency, including comfort validating high-volume calculations, tracing source-system data to billing and GL outputs, and partnering with data or engineering teams. - Practical experience applying AI, analytics, or automation in a Finance org, with clear judgment about controls, review points, and limits of automation. - Balanced materiality and risk judgment: able to quantify impact, identify root cause, assess control implications, and recommend proportionate action backed by evidence. - Experience with Oracle Fusion ERP, revenue systems, billing platforms, or finance transformation work. - Passion for technology, AI, and building financial infrastructure that lets new products scale responsibly.
