Senior SAP Ariba Application Engineer

Senior SAP Ariba Application Engineer - Warsaw, Poland (Hybrid) Full Time

Hybrid: 3 days/week in the Warsaw office, 2 remote.

About the role

Our client, a fast-growing global biopharmaceutical company, is scaling its Source-to-Pay platform and needs a senior Ariba engineer to be the technical backbone of it — owning support, configuration, and continuous improvement across the full Ariba suite (Sourcing, Contracts, SLP, Buying, Invoicing), and acting as the escalation point when things get hard.

This isn't a ticket-queue role. You'll do deep root-cause work, lead post-incident reviews, shape how Procurement, Finance, and AP teams actually use the platform, and mentor the engineers below you. You'll work directly with SAP, internal technical teams, and outside vendors to keep a complex, global system running clean.

What you'll own

• Advanced troubleshooting and permanent fixes across Ariba's upstream and downstream modules
• Configuration and optimization tied to real business needs, not just tickets
• Incident, problem, and change management, with documentation that actually gets used
• Integration performance across CIG, APIs, and middleware — plus the S/4HANA handoffs
• Release testing, regression checks, and change impact assessment
• Mentorship for L2 support engineers as the support model matures

What you bring

• 4+ years hands-on with SAP Ariba, across both upstream and downstream modules
• Real ITSM chops — incident, request, change, and problem management
• Comfort with integration frameworks (CI-9, APIs, middleware) and cross-system debugging
• A working knowledge of Agile/DevOps and secure development practices
• The communication skills to be the calm, credible voice when something's on fire
• Bachelor's degree in Information Systems, Engineering, Business, or a related field

Nice to have

• Life sciences or pharma experience in a regulated environment
• SAP Ariba or SAP certification
• Experience working across global, multicultural teams
