You'll work where Causa Prima meets the SAP systems our customers run their finance on. Most of the data we care about lives inside S/4HANA and ECC, and your job is to make those systems work cleanly and reliably with what we build. You'll bring real ABAP skill and a working understanding of finance in SAP, and you'll grow into a role that sits right at the intersection of enterprise software and AI.
What you'll do
- ABAP development: Write clean, reviewable ABAP inside our reserved namespace. Function modules, CDS views, and extensions that respect the customer's release strategy and stay upgrade-safe.
- SAP data and APIs: Work with SAP's standard APIs and data model (OData, BAPIs, RFCs, IDocs) to read and write the financial data our product depends on.
- FI/CO domain work: Translate accounting reality into code. Document types, posting logic, payment terms and Skonto, open item management, account determination, master data, tax codes. You understand what a transaction actually does to the ledger before you automate anything.
- Data structuring:



Make sense of heterogeneous customer SAP setups (different charts of accounts, company codes, country versions) and shape that data into something consistent and usable downstream.
- Reliability and auditability: Build with idempotency, error handling, and reconciliation in mind. Every action against a customer system should be traceable.
- Customer-facing problem solving: Sit with finance teams and SAP admins during onboarding, understand their configuration, and turn "it's complicated in our system" into something that works.

What we're looking for
- 2 to 4 years of hands-on SAP experience, with real ABAP development behind you (not just configuration).
- Working knowledge of SAP FI/CO: you can explain a three-way match, a Skonto posting, and open item clearing without reaching for a manual.
- ABAP fundamentals done well: function modules, BAPIs, CDS views, and an instinct for what makes code upgrade-safe and namespace
