Senior Manager, Finance Transformation Finance London

Checkout.com is where the world checks out. Our global network powers billions of transactions every year, making money move without making a fuss. We spent years perfecting a service most people will never notice. Because when digital payments just work, businesses grow, customers stay, and no one stops to think about why.

With 19 offices spanning six continents, we feel at home everywhere – but London is our HQ. Wherever our people work their magic, they’re fast-moving, performance-obsessed, and driven by being better every day. Ideal. Because a role here isn’t just another job; it’s a career-defining opportunity to build the future of fintech.

This is a high-impact leadership role within our core Finance team in London, designed for a Finance Transformation leader who wants to shape the backbone of our financial infrastructure. As a Senior Manager of Finance Transformation, you will be the primary Finance Lead responsible for the Accounting Logic, Business Process, and Integrity Controls of our Accounting Rules Engine and Sub-ledger implementation.

This role comes at a pivotal time as Checkout transforms the Financial Platform to power our future growth. Partnering closely with Product and Engineering, you will ensure our sub-ledger environment provides a robust, auditable foundation—building the deep financial trust and transparency required to support Checkout’s continued growth.

• Accounting Rules Engine Design: Lead the definition and maintenance of the accounting rules engine. You will translate business products and events into precise double-entry accounting logic (IFRS) to ensure automated, real-time posting to the ledger.
• Sub-ledger Implementation: Drive the business adoption of the sub-ledger, ensuring it seamlessly integrates with upstream product systems and downstream General Ledger (GL) reporting and controls.
• Business Process Migration: Lead the migration of legacy business processes into the new system architecture, ensuring data integrity, historical continuity, and seamless transition of the month-end close.
• Process Design & Optimisation: Scrutinise existing "as-is" processes to identify inefficiencies. You will design scalable "to-be" workflows that leverage data products to drive an accelerated, "zero-touch" financial close.
• Strategic Stakeholder Management: Act as the bridge between Finance, Engineering, and Product teams to ensure the Accounting Rules Engine reflects the commercial reality of our products.
• Governance & Control Oversight: Embed robust automated controls within the sub-ledger framework, maintaining strict compliance with internal policies and international accounting standards (IFRS).

• Strong Accounting Skillset: A professional accounting qualification (ACCA, ACA, CIMA, or equivalent) is mandatory. You must have a "first-principles" understanding of accounting to drive the business requirements for accounting rules.
• Sub-ledger & Rules Engine Expertise: Proven experience in implementing or managing a sub-ledger (e.g., Oracle FAH, SAP FPSL, or proprietary fintech engines). You must understand how to map high-volume transactional data to accounting journals.
• Complex Migrations: Demonstrable experience leading the migration of financial data and business processes from legacy systems to modern cloud-based financial platforms.
• Technical Literacy: Ability to communicate effectively with engineers. While you don't need to code, you should be comfortable discussing data schemas, API integrations, and system logic.
• Proven Transformation Delivery: Experience leading finance change in a fast-paced environment (Fintech or Payments preferred).
• Leadership & Influence: Proven track record of managing cross-functional project teams and influencing senior stakeholders on technical system decisions.
• Data Analysis (Advantageous): Proficiency in SQL is highly desirable to assist in data mapping and reconciliation during the migration phase.
