About the role

Posted: 2026-11-03

Flex is a growth-stage, NYC headquartered FinTech company that is building the payment layer for life's financial obligations, giving households one place to see, split, and pay their bills around how they live and get paid. By offering greater choice over how and when payments are made and allowing eligible on time payments to help build a positive credit history, Flex puts households back in control of their cash flow.

That work brings together people with different perspectives who challenge the status quo and take ownership of solving difficult problems. For you, that means doing the best work of your career next to people who make you better, and together bringing ideas to life that make a real impact for the people we serve.

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 would 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

What they are looking for

Required

- 10+ years of experience in financial systems, accounting technology, or a closely related field — with meaningful time spent in a high-growth or scaling environment

- Deep ERP expertise — ideally including implementation experience (go-live, integration design, configuration, and post-live optimization) with platforms such as NetSuite, Campfire, Sage Intacct, or equivalent

- Strong finance and accounting foundation — sufficient understanding of US GAAP, month-end close processes, and financial reporting to both translate business requirements into systems design and identify where process redesign itself is the better answer, without losing fidelity

- Demonstrated experience building or owning IT General Controls and access control frameworks — SOD enforcement, user provisioning, change management, and audit-trail documentation

- Strong grasp of financial master data design and governance — chart of accounts structure, dimension/segment design, and the data architecture decisions that determine downstream reporting flexibility

- Demonstrated ability to design or re-engineer core accounting processes (close, AP, payroll, or similar) around best practices — not just automate existing process but rethink it

- Experience working directly with external auditors (Big 4 preferred) on IT controls testing and audit evidence standards

- Hands-on experience with API integrations and data pipeline design — comfort working with Engineering teams to scope and spec integration work

- Genuine enthusiasm for AI and automation — you think naturally about where agent-based workflows can replace manual processes, and you’re excited to build them

- Exceptional communication skills — ability to translate between finance, engineering, and executive audiences without oversimplifying or losing technical precision

- Comfort building and scaling in a fast-paced, resource-constrained environment — this is very much a “build the plane while flying it” role, and success will depend on strong prioritization instincts and the ability to move quickly as priorities shift

Strongly Preferred

- Experience with Campfire or another AI-native ERP platform — distinct from legacy systems, these environments call for a different way of thinking about configuration and workflow design

- Experience designing or operating AI-automated workflows in a finance or accounting context — intelligent document processing, transaction coding automation, or similar

- SOX compliance experience, including ITGC documentation, RCM design, and internal or external audit support — ideally in a pre-IPO or newly public company

- Experience with close management platforms (FloQast, BlackLine, or equivalent) and financial reporting automation tooling

- Prior experience at a fintech, payments company, or similarly regulated financial services environment

- CPA or equivalent credential is a plus, not a requirement

- Formal project management experience or training — this role requires running complex, cross-functional projects to completion, not just providing technical and functional expertise

- Experience leading close process optimization or standardization initiatives, ideally reducing close timelines or manual touch-points

- Familiarity with payroll and AP operational best practices — vendor management, payment controls, exception handling — beyond the systems that support them
