Assistant(e) Administratif(ve) et Comptable - Luxembourg

An Administrative and Accounting Assistant. Ensure the daily administrative and accounting management of the Education subsidiary in Luxembourg, while providing direct support to the Director of the subsidiary, in a context of regular exchanges with international partners (USA, UK, Africa). The holder of the position guarantees the conformity of operations, the quality of administrative monitoring and the fluidity of cross-border exchanges. In close collaboration with the Director of the Education subsidiary and the Europe Area Manager, this role is the administrative and accounting pivot which secures the daily operation of the subsidiary and streamlines communication with the Cybastion group headquarters and foreign partners.

What this post is, and is not. This is not a full-fledged general accounting position nor a simple secretarial role: it is a hybrid role which combines management assistantship, rigorous administrative monitoring and accounting preparation, requiring as much discretion as organizational skills. This position is not suitable for someone looking for a fixed framework — the subsidiary is growing and priorities are changing.

What you will build

• Administrative management of the subsidiary: monitoring of letters, official documents, archiving, contracts and internal files, coordination with the Cybastion group headquarters.
• Accounting and financial monitoring: collection, verification and classification of accounting documents, monitoring of payments and reminders, preparation of elements for the accounting firm, contribution to audits.
• Direct support to the Director of the subsidiary: diary management, organization of meetings and travel, preparation of files, presentations and strategic documents.
• International coordination (USA, UK, Africa): administrative and accounting communication with foreign partners, transmission of cross-border documents, in French and English.
• Routine budget monitoring: participation in controlling expenses and preparing financial reports for management.

Who we are looking for

Non-negotiable cultural profile: A rigorous, organized and discreet person, capable of managing sensitive information reliably and juggling several priorities without losing quality. Versatility and a sense of service are essential — this position requires you to be as comfortable in management assistance as in preparing accounting documents. Credibility is built by the reliability of the documents produced, compliance with deadlines, and the fluidity of communication with multicultural interlocutors.

2 to 5 years of experience in a similar function (administration, accounting or management assistantship). Proven track record in administrative management and daily accounting monitoring. Rigor and attention to detail as well as discretion and reliability are non-negotiable. Professional English is an important asset alongside a mastery of French, given regular exchanges with the USA, UK and Africa. Experience in an international or multicultural environment is a plus. A Bac+2 to Bac+3 diploma in administration, accounting or management is required; knowledge of administrative and accounting practices in Luxembourg is an asset.
