Requirements

• Strong architecture experience around Microsoft Dynamics 365 Finance & Operations / Dynamics 365 Finance.
• Proven experience designing solutions across multiple enterprise platforms rather than operating purely within D365.
• Strong understanding of finance, billing, Accounts Receivable and Order-to-Cash processes.

• Experience with complex payments, payment gateways, merchant services or card processing.
• Exposure to consumer-finance/lender integrations, remittance processing or high-volume settlement would be highly valuable.
• Understanding of SAP S/4HANA / SAP FI and coexistence or integration between SAP and Dynamics would be advantageous.

• Strong stakeholder management skills and the credibility to work directly with senior Finance and enterprise architecture stakeholders.
• Experience within utilities, energy, financial services, subscription businesses or other complex high-volume billing environments would be particularly relevant.

Responsibilities

• Own the end-to-end solution architecture across the finance and billing landscape, working closely with Finance, Dynamics, Salesforce, AWS/integration and wider architecture teams.
• Define the end-to-end architecture across Salesforce, AWS, Dynamics 365 F&O and SAP S/4HANA.
• Own integration patterns for billing, amended sales processes, payments, settlements and financial reporting.
• Define how existing D365 Order-to-Bill and Subscription Billing frameworks can be reused and where new patterns are required.
• Architect payment flows incorporating card payments, pre-authorisation/tokenisation, multiple merchant accounts and settlement reconciliation.
• Define integration patterns with multiple consumer-finance/lending providers, including funding requests, remittance ingestion and high-volume settlement matching.
• Ensure new D365 processes integrate safely into the existing SAP S/4HANA finance landscape.
• Establish robust approaches to error handling, reconciliation, exception management, auditability and operational visibility.
• Lead architectural decisions around where functionality should sit across D365, Salesforce, AWS and surrounding platforms.
• Work with functional and technical specialists to turn high-level business epics into a coherent target architecture.
