Flex is a growth-stage, NYC headquartered FinTech company that is creating the best rent payment experience. It’s hard to believe that it’s 2026 and paying rent on time is expensive, inflexible, and difficult. We’re here to change that! Flex enables our users to pay rent throughout the month on a schedule that better fits their finances and budget. Our mission is to empower as many renters as possible with flexibility over their most significant recurring expense. After deliberately keeping a stealth profile as we built up unprecedented investor support and an enthusiastic user base, we are looking for motivated individuals to help us keep our mission growing. Will you be a part of the team? About the Role We are seeking a strategic leader who pairs deep systems expertise with strong process design instincts to build and own Flex's Financial Systems & Transformation function from the ground up. This is a rare opportunity to define a new pillar within the Finance organization at a fast-scaling fintech — one where the scope extends well beyond traditional ERP administration into agentic AI infrastructure, process automation, and the controls architecture that will underpin Flex’s next phase of growth. As Director, Financial Systems & Transformation, you will own the internal financial systems that power Flex’s accounting and financial reporting function — including our core ERP, procure-to-pay (P2P), T&E systems, and additional financial reporting tooling as the function matures. You will also design, build, and maintain the AI-powered workflows that are central to Flex’s vision for a modern, scalable Finance function, and you will lead the build-out of ITGC and financial systems controls that keep pace with the business as it scales. This role sits at the intersection of finance, systems, and AI — and requires a leader who can operate with fluency across all three. You will partner closely with the VP Controller, the broader Finance leadership team, and Flex’s Engineering and AI Central teams to make the vision real. This position will be based in our New York headquarters on a hybrid basis and will report to the VP Controller.    What You'll Do Financial Systems Ownership & Administration Own our ERP (Campfire) as Flex’s financial system of record — including configuration, close module setup, chart of accounts and dimension/segment governance, and ongoing system health Own our procure-to-pay (P2P) systems for AP and T&E — evaluating near-term enhancements and long-term tooling strategy as we scale Manage integrations between core financial systems and the upstream/downstream data sources that feed them — including the payroll (Rippling) integration in partnership with the People/HRIS systems team — ensuring accurate, timely, and auditable data flows across the Finance stack Serve as the internal product owner for financial systems enhancements — translating Finance team requirements into system configuration and working with vendors and technical teams where needed Partner with the Strategic Finance team on the evaluation, implementation, and ongoing administration of FP&A tooling, supporting both the Finance and business planning functions Evaluate, implement, and administer additional tooling across Finance as the function scales — including financial reporting, SOX, and account reconciliations Agentic AI Infrastructure Design, build, and maintain AI-powered workflows that eliminate manual, high-volume processes across the Finance function — with a particular focus on transaction coding, close automation, and financial reporting Own the technical architecture for agent-as-preparer workflows: defining confidence thresholds and exception routing, and building the audit trail infrastructure required in a controls-conscious environment Partner with Flex’s AI Central team to extend our internal AI platform in
