SAP S/4HANA Integration & Partner Systems Manager

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.

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.
