We are seeking a seasoned SAP FICO Engineer to lead the design, integration, and support of Poland’s mandatory e-invoicing (KSeF 2.0) within SAP ECC or S/4HANA. You will own the end-to-end solution leveraging SAP Document and Reporting Compliance (SAP DRC) and related interfaces, ensuring compliance with FA(3) XML schema, authentication/authorization flows, and operational processes aligned to the February 1 / April 1, 2026 rollout.

Key Responsibilities

• Lead KSeF 2.0 enablement in SAP (ECC or S/4HANA): design/configure e-invoice issuance, receipt, and storage via SAP DRC; align to FA(3) schema and KSeF validation/ID assignment.
• Integrate and harden inbound/outbound flows (AR/AP), manage tax codes, partner profiles, and error handling; implement contingency Offline24 and QR processes where applicable.
• Establish KSeF access & security (certificates/tokens, role-based permissions), auditability, and operational monitoring (jobs, queues, exceptions).
• Collaborate with Finance/Tax on Polish VAT specifics (JPK_VAT updates, exemptions, attachments/Zalacznik node), and maintain regulatory alignment.
• Design data and integration across FI/CO (GL, AR, AP, AA, CO-PC), and cross-module touchpoints (MM, SD), including ABAP debugging for issue isolation.
• Testing & release management: author functional specs, unit/SIT/UAT plans; drive cutover; ensure production readiness with dashboards and KPIs.
• Support & knowledge transfer: build playbooks, train key users, and hand over to support; establish SLAs for incident/change management.

Qualifications

• 7–10+ years in SAP FI/CO (ECC or S/4HANA), with strong configuration across GL/AR/AP/AA/CO; proven ABAP debugging skills.
• Hands-on e-invoicing experience in Poland: KSeF 2.0 implementation (FA(3) XML, KSeF IDs), SAP DRC enablement, familiarity with phased 2026 timelines.
• Knowledge of Polish VAT & JPK_VAT reporting changes effective Dec 2025 / 2026 and practical experience with authorizations/certificates for KSeF.
• Cross-module integration (MM/SD) and performance/stability design for high-volume invoicing; experience in contingency (Offline24) flows preferred.
• Languages: Polish (professional working) and English (B2/C1).
• Degree in Finance, Accounting, IT, or equivalent practical experience.

Nice to Have

Exposure to FSCM/TRM and cash applications; S/4HANA migration or greenfield experience.

Prior rollout of e-invoicing in other jurisdictions (e.g., EU EN-16931 variants) and multi-country SAP DRC deployments.
