You'll own the layer 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 you'll be the person who decides how we read from and write to those systems safely, at scale, across very different customer landscapes. This is a senior individual contributor role with real architectural ownership: you'll set the patterns the rest of the team builds on, and you'll be the technical voice in the room when a customer's SAP team asks hard questions.

What you'll do

Own the add-on:

Architectural ownership of our ABAP add-on in its registered namespace: how it's structured, released, and kept upgrade-safe.

Clean core and certification:

Drive us toward clean core compliance and SAP certification, using released CDS and public APIs wherever they exist.

SAP data and APIs:

Design how financial data moves in and out of SAP (OData, BAPIs, RFCs, IDocs) at production volume.

FI/CO domain leadership:

Turn accounting reality into code: posting logic, payment terms and Skonto, open item management,



account determination, tax codes.

Set the engineering bar:

Define the conventions and raise the standard for testability, ABAP Unit coverage, and static analysis (ATC, SCI).

Data structuring across landscapes:

Shape heterogeneous customer setups (charts of accounts, company codes, country versions, ECC versus S/4HANA) into one consistent model.

Reliability and auditability:

Build for idempotency, reconciliation, and traceability, so every action against a customer system is explainable after the fact.

Customer-facing technical lead:

Lead technical discovery and onboarding with finance teams, SAP admins, and customer Basis teams.

What we're looking for

At least 6 years of hands-on ABAP development on S/4HANA and ECC (not configuration with some coding attached).

ABAP you've shipped into someone else's production system, with the upgrade cycles, transports, and volume problems that follow.
