Block is one company built from many blocks, all united by the same purpose of economic empowerment. The blocks that form our foundational teams — People, Finance, Counsel, Hardware, Information Security, Platform Infrastructure Engineering, and more — provide support and guidance at the corporate level. We are looking for a strategic and hands-on systems architect to lead the next wave of finance technology transformation at Block. This role will sit at the intersection of Accounting, Tax, Treasury, Procurement, and FP&A technologies, helping design and scale the technology stack that powers the core financial engine of the company. The ideal candidate brings deep expertise in financial systems architecture, a product-thinking mindset, and the ability to span both strategic planning and execution. You’ll serve as the connective tissue between finance functions and engineering - with a clear vision for the future state of Block’s finance tech stack, optimized for automation, speed, accuracy, and resilience. An AI-first mindset is essential, with demonstrated experience applying AI to financial workflows. Key Responsibilities

Design and evolve the end-to-end finance systems architecture, spanning Record-to-Report (R2R), Source-to-Pay (S2P), Treasury, Tax, Planning, and Reporting. Drive future-state design by assessing current processes, identifying optimization opportunities, and architecting scalable, automated solutions. Create architectural frameworks that unify accounting, tax, treasury, FP&A, and procurement tech verticals around shared data models, integrations, and workflow automation. Champion an AI-first architecture, embedding AI and ML in areas like reconciliations, flux analysis, anomaly detection, and system self-service. Requirements

15+ years in financial systems architecture or enterprise systems engineering. Deep hands-on experience with Oracle Fusion Finance, Fusion Accounting Hub (FAH), and financial data modeling. Expertise across Revenue (incl. ASC 606), Intercompany, Consolidations, Tax, Treasury, and FP&A. Proven track record designing systems for close acceleration, automation, and finance transformation. Experience working closely with Engineering, Product, Accounting, and Data teams to translate strategy into execution.
