Joining Moderna means advancing mRNA science to transform medicine. Work with exceptional global teams on a broad pipeline and build a career that makes a real difference for patients. Moderna is strengthening its international business services hub in Warsaw, supporting our growing global operations. We welcome professionals ready to help advance our mission and shape the future of mRNA medicines. This is a global individual contributor opportunity to take day-to-day ownership of a portfolio of business-critical Procurement and Legal applications, with an immediate focus on SAP Ariba and its integration with SAP S/4HANA. Reporting to the Director, Digital Legal & Procurement Systems, you’ll operate with significant autonomy, partnering with global Procurement process owners to translate complex business needs into well-designed, measurable digital outcomes. You’ll combine deep end-to-end Procurement knowledge with strong product judgment and technical fluency, taking work from intake and prioritization through design, delivery, release, production support, and continuous improvement. You’ll investigate complex cross-platform issues through evidence and root-cause analysis, guide distributed technical resources and external service providers, and build the controls and documentation required for reliable, audit-ready enterprise platforms. The role also offers the opportunity to get close to Generative AI tools and explore where AI-enabled approaches can improve product ownership, knowledge management, requirements, analysis, documentation, operational efficiency, and the broader digital experience across Procurement and Legal systems. Here's What You'll Do: Own the end-to-end intake and delivery backlog for global Procurement and Legal systems, translating priorities into clear epics, stories, acceptance criteria, dependencies, and delivery commitments. Evaluate requests based on business value, effort, risk, and urgency, recommending whether work should proceed, be reshaped, deferred, or declined, while communicating trade-offs transparently. Translate business needs and end-to-end processes into clear requirements, process and functional designs, integration needs, test scenarios, and release plans. Apply pragmatic Agile practices to create clarity, accountability, and predictable delivery, facilitating only those processes and ceremonies that add value. Measure product health and outcomes through backlog quality, delivery predictability, release quality, recurring incidents, manual effort, control effectiveness, and documentation coverage. Maintain strong working knowledge of application environments, configurations, master data, dependencies, and integrations, using this knowledge to trace issues across SAP Ariba, SAP S/4HANA, and the integration layer and drive remediation where gaps exist. Lead major application releases from end to end, including impact assessment, environment and integration readiness, testing, defect resolution, cutover, and stabilization. Triage production issues, distinguishing isolated symptoms from systemic problems, and use ticket trends and root-cause analysis to drive durable improvements that reduce repeat incidents and manual effort. Ensure production issues have clear ownership and documentation and are driven through resolution to confirmed closure. Own the execution and continuous improvement of SOX-relevant application controls, including access and segregation of duties, change and release management, integration and data integrity, audit evidence, security and privacy, and third-party access. Maintain a comprehensive application handbook covering environments, configurations, integrations, controls, procedures, decisions, ownership, known issues, and risks, enabling future owners to transition effectively without costly rediscovery.
