The posting
Adservio Luxembourg Adservio Luxembourg is the Luxembourg arm of Adservio Group, 300+ consultants across Paris, Brussels and Luxembourg, 15 years serving regulated industries. We opened in Luxembourg in 2022 and work across financial services, energy and utilities, transport and mobility, insurance and the public sector: wherever compliance is not optional and failure is not acceptable. You join our Operations team.
The context With our team, you work for a regulated European payments fintech whose Group Accounting function is in transformation. At stake: a reliable close across several entities and currencies, one trusted accounting source of truth, and documentation that withstands statutory audit. Twelve months, extendable, from Luxembourg or remotely within Europe.
Your mission You bring senior, hands-on capacity, neither bookkeeping nor review-only, and leave the function better controlled than you found it.
Close and ownership
- You own entities, balance-sheet areas or workstreams through month-end: journals, accruals, reconciliations.
- You explain material movements and help shorten the closing timetable.
- You work with Treasury, FP&A, Tax and local accounting providers.
Remediation
- You clean up unsupported, unreconciled or misclassified historical balances and rebuild clear audit trails.
- You resolve intercompany, cash and FX discrepancies and document complex transactions in technical memos.
- You fix recurring posting and master-data issues at the source.
Audit and controls
- You answer external auditors directly for European legal entities.
- You document procedures, strengthen controls and automate where it pays off.
Your profile You structure your own work and flag risks early.
What is essential
- At least seven years of hands-on financial accounting, owning month-end for entities or material balance-sheet areas.
- Multi-entity, multi-currency accounting under IFRS and European local statutory frameworks.
- Complex or historical issues resolved, backed by technical papers and audit documentation.
- Statutory or group audit support, and management of local accounting and tax providers.
- Advanced Excel and a major ERP, ideally SAP S/4HANA.
What makes the difference
- Group reporting, first-time consolidation or post-ERP remediation.
- ACCA, ACA, CPA, CIMA or national equivalent; payments or banking background.
- Power Query, SQL, AI-supported workflows, ISO 20022 (CAMT) bank statements.
Languages Required: professional fluency in English.
