Purpose of the job

As Finance Systems Integration Manager you will be accountable for the functional and process leadership of SAP Business One (SAP B1) integrations across the global Finance Systems landscape.

You'll reduce dependency on individual subject-matter expertise by building a sustainable integration delivery model: clear ownership, shared developer knowledge, documented support procedures, standardized handovers and controlled escalation from FIS Support.

This role operates largely remote within the UK.

Key responsibilities

• Act as the Finance Systems integration subject matter expert for SAP B1 connected services such as Hub, Noosh, Tipalti, Tungsten, Concur, Blackline, journaling services, tax payloads, reporting/data warehouse feeds and others
• Partner with FIS Support so BAU incidents are handled through the support front door, while complex integration escalations are analysed for root cause, permanent fix, prevention and knowledge transfer
• Partner with the FIS Senior Project Manager on project intake, roadmap planning and release governance where an item has integration impact, providing sizing input, dependency analysis and delivery risk assessment
• Partner with the ERP FIS Manager and functional consultants on system accounting implications, SAP B1 process design and control considerations for upstream or downstream finance changes
• Set and maintain integration documentation standards, including functional overview documents, solution notes, payload/process mappings, known error playbooks, operational runbooks and release handover packs
• Manage external vendor and partner alignment for integration changes, ensuring statements of work, estimates, dependencies, assumptions, issue resolution and delivery dates are credible and actively managed
• Drive continuous improvement in integration ownership by reducing bottlenecks, cross training developers, improving documentation, strengthening monitoring and embedding repeatable delivery practices
• Ensure all integration changes follow change control, auditability, segregation of duties, release governance and production stability expectations for global finance systems

Knowledge, skills and experience

• Strong experience working with SAP Business One / SAP B1 in a finance systems, systems accounting, business analysis, integration delivery or solution delivery capacity
• Proven experience managing or leading technical resources such as developers, integration specialists, infrastructure engineers or external development partners
• Delivering or supporting finance system integrations involving ERP, ordering platforms, AP / AR automation, payment platforms, tax engines, data warehouse/reporting or middleware/API services
• Ability to lead developers from a functional/process perspective and challenge solution approach, estimates, dependencies and release readiness without necessarily being the hands-on developer
• Translating finance process requirements into functional specifications, integration requirements, test cases and supportable production solutions
• Strong understanding of finance operations processes such as invoicing, credit/re-invoice, AP, AR, payments, journals, tax, period-end activities and reporting dependencies
• Managing integration defects through root-cause analysis, workaround definition, permanent fix design, regression testing and support handover
• Working in a global or multi-entity finance environment with multiple stakeholder groups, competing priorities and strong control expectations

• Platforms such as Tipalti, Tungsten Automation, BlackLine, Concur, Thomson Reuters tax solutions, HSBC automated payments, internal ordering systems or finance data warehouses
• Working with external SAP B1 partners, offshore / nearshore development teams or managed service providers
• Setting delivery standards for developers, including documentation quality, peer review, version control, release notes, support handover and knowledge sharing
• Documenting integration architecture, process maps, payload mappings, error-handling procedures and operational support runbooks
• Understanding of controls, audit requirements, infrastructure dependencies and data governance in finance systems
• Use of Jira, Zendesk, Smartsheet, Power BI, Lucidchart or similar project, support, reporting and documentation tools
