SAP S/4HANA Integration & Partner Systems Manager

Job Description

Your responsibilities

Partner-system dependency management

• Own and maintain an end-to-end view of dependencies between LUCA and the relevant SAP and non-SAP partner systems, covering business processes, data, interfaces, environments, testing, cutover and operational readiness.
• Identify interdependencies early, clarify owners and required decisions, and translate them into traceable milestones, deliverables, assumptions, risks and actions.
• Coordinate dependency planning across LUCA workstreams and partner-system roadmaps, highlighting sequencing constraints and potential impacts on rollout readiness.
• Act as the central coordination point for partner-system integration topics, ensuring that open points are assigned, followed up, escalated and resolved in a timely manner.

Functional and technical integration

• Understand end-to-end Finance processes and assess how changes in LUCA affect upstream and downstream partner systems, business controls and operational activities.
• Facilitate alignment between functional requirements and technical integration design, ensuring that business intent, data needs, processing logic and non-functional constraints are understood by all parties.
• Coordinate the design and implementation of integration scenarios between SAP S/4HANA and SAP or non-SAP systems, including interfaces, data flows, middleware dependencies and migration-related connections.
• Challenge incomplete or inconsistent requirements and support teams in reaching practical, sustainable and reusable integration solutions.
• Ensure integration decisions, interface scope, ownership, dependencies and acceptance criteria are documented and aligned with the LUCA template and rollout approach.

Testing, cutover and readiness

• Coordinate partner-system participation in integration testing, end-to-end testing, regression testing and defect resolution, with clear entry criteria, test data needs, responsibilities and evidence.
• Ensure cross-system defects are analysed from both functional and technical perspectives and driven to sustainable resolution across organisational boundaries.
• Plan and coordinate partner-system activities within rehearsal and cutover plans, including connectivity, transports or releases, data preparation, interface activation, validation and fallback dependencies.
• Assess partner-system readiness and provide transparent status, risks, decisions and recommendations to the relevant LUCA governance forums.
• Support hypercare and stabilisation by coordinating cross-system issue resolution, monitoring critical dependencies and ensuring effective handover to support organisations.

Governance and stakeholder engagement

• Build effective working relationships with LUCA functional and technical teams, business users, partner-system owners, internal IT providers and implementation partners.
• Prepare and facilitate integration and dependency forums, focusing discussions on decisions, delivery commitments, risks, unresolved topics and upcoming milestones.
• Maintain clear integration documentation, dependency logs, decision records, status reporting and escalation paths using the programme’s agreed tools and standards.
• Communicate complex functional and technical topics in a concise, audience-appropriate manner and create shared understanding between business and technology stakeholders.
• Contribute to the continuous improvement of LUCA integration governance, reusable methods, templates and lessons learned across rollout waves.

Qualifications

Experience and knowledge

• Bachelor’s or Master’s degree in Information Technology, Computer Science, Business Informatics, Finance or a related discipline.
• At least 8 years of experience in multinational SAP transformation or ERP implementation environments, including participation in at least one full implementation cycle.
• Strong experience coordinating integrations and interdependencies across SAP and non-SAP systems in complex programme landscapes.
• Balanced functional and technical understanding: the ability to follow Finance process discussions while engaging credibly on interfaces, data flows, integration architecture, middleware, environments and testing.
• Good knowledge of SAP Finance processes and modules, particularly subledger processes and their integration points with surrounding systems.
• Experience in cross-system testing, cutover planning, release coordination, defect management and operational readiness.
• Proven ability to coordinate internal IT teams, business stakeholders and implementation partners without relying solely on direct authority.
• Experience with integration and delivery documentation, dependency tracking, risk and issue management, and structured status reporting.
• PMP, SAP or comparable integration certification is advantageous but not required.

Ways of working

• Systems-thinking mindset with the ability to connect business-process impacts, technology dependencies, data flows and delivery timelines.
• Strong analytical and problem-solving capability, including the ability to structure ambiguity and drive cross-team topics to decisions and closure.
• Clear, articulate and confident communication with both functional and technical stakeholders at different levels of seniority.
• Collaborative and diplomatic approach, combined with the persistence to challenge constructively, secure commitments and escalate when necessary.
• High level of ownership, reliability and attention to detail in a fast-paced, multicultural programme environment.
• Excellent written and spoken English and experience working in a European and multinational business environment.
