ARQUIMEA, we are a technology company operating globally and providing innovate solutions and products in highly demanding sectors.

Our areas of activity are Aerospace, Defense & Security, Big Science, Biotechnology and Fintech.

Main function and scope:

• Act as Arquimea's internal functional owner for SAP S/4HANA Finance and Controlling (FI/CO) throughout the ERP implementation lifecycle (blueprint, build, SIT/UAT, cutover, go-live, hypercare). Ensure end-to-end process integrity, auditability, and operational stability, coordinating business stakeholders, IT, and the implementation partner.

• Scope and module ownership: FI/CO is the core domain (primary ownership). Project System (PS), Procurement & Inventory (MM) and Warehouse Management (EWM) are handled as integration touchpoints, focusing on financial postings, inventory valuation, GR/IR reconciliation and project settlement.

Key Functions:

Business process ownership (Fit-to-Standard)

• Lead To-Be design for Record-to-Report (R2R), Procure-to-Pay (P2P), Order-to-Cash (O2C) where applicable, Inventory & Valuation, and Project Cost Control (PS/CO).

• Drive fit-to-standard decisions, documenting gaps, alternatives, and scope trade-offs.

Finance & Controlling (FI/CO)

• Define and validate: chart of accounts alignment, posting logic, taxes/local compliance requirements (as defined by Arquimea), asset accounting, closing procedures, cost center structures, internal orders, allocation/settlement principles, WIP/variance concepts (where applicable).

Projects (PS)

• Own governance and design of WBS structures, budgeting/availability control, project settlement rules, integration of PS with CO/FI postings, reporting by project (actuals, commitments, margin).

• Define how project structures drive procurement/inventory segregation and reporting.

Logistics/Inventory (MM/EWM)

• Own process and configuration validation for purchasing, goods receipt, returns, GR/IR behavior, inventory movements, and their accounting impact.

• Lead EWM design validation: warehouse structure, stock types/statuses, putaway/picking/staging, physical inventory, returns flows, integration points with QM/Production.

Integration & data

• Co-own functional requirements for interfaces impacting FI/CO/PS/MM/EWM (banking, billing/invoicing, reporting/Power BI, PLM touchpoints affecting valuation/account assignment).

• Define master data standards for materials (accounting views), valuation classes, storage locations/warehouse numbers, batch/serial financial implications, vendor/customer financial data.

Testing, cutover, and stabilization

• Own UAT scripts for finance, PS, procurement, inventory and EWM; lead defect triage and acceptance sign-off.

• Lead reconciliations during migration/cutover: opening balances, inventory qty/value, GR/IR, AP/AR open items, asset data.

• Run hypercare functional stabilization and handover to steady-state support (runbooks, controls, KPIs).

Required candidate profile:

• Bachelor's degree in Business Administration, Finance, Industrial Engineering, Information Systems, or similar.

• Desirable: Master in Finance/Controlling, ERP/SAP specialization, or Supply Chain.

Specific Knowledge Required:

• SAP S/4HANA functional knowledge in:

  • FI/CO (core financial postings and closing)

  • PS (project cost control and settlement concepts)

  • MM (procurement and inventory)

  • EWM (warehouse execution)

• Understanding of auditability, segregation of duties, and role-based access (Fiori authorization concepts at functional level).

• Strong capability in Excel/CSV for migration validation and reconciliations.

Minimum Experience Required

• 5+ years in SAP functional roles (S/4HANA preferred).

• At least one full-cycle implementation (blueprint to go-live/hypercare).

• Proven experience in FI/CO + MM; PS ownership strongly preferred; EWM desirable.
