Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following the close of a $200M Series B, valuing the company at $1.4 billion, we are expanding our teams and capabilities to deliver mission-critical systems to allied forces.
Our work is guided by clear values: building technologies with real-world impact, pursuing excellence in everything we do, setting ambitious goals, and taking on the hardest technical challenges. We operate in a demanding environment where rigor, ownership, and execution are expected.
About the role
Harmattan AI operates a group of nine entities across France, Switzerland, the US, UK, UAE, and Morocco.
With our ongoing expansion, the Finance Team is handling an increasing number of invoices and expense claims across various entities. To allow permanent staff to focus on controls, intercompany processes, and closing tasks, dependable support is required for recurring P2P and banking activities.
We are seeking an Accounting Assistant Apprentice to provide operational support for the purchase-to-pay (P2P) cycle and bank bookkeeping as we build out our accounting function and implement Odoo. In this role, you will be responsible for recording transactions, preparing documentation, and performing first-level accounting checks.

- Manual Expense Claims: Process mileage allowances by checking rates, ensuring consistency between trips and supporting documents, and applying caps.
- Supplier Invoices: Record invoices in Odoo, ensuring matching with approvals as well as accurate accounting and analytical coding.
- Supplier/Bank Details (RIB): Create and verify supplier records and bank details, limited to preparation and document control.
- Treasury: Categorise bank transactions in Odoo ; perform bank reconciliations for the French entities.
Candidate Requirements
- As a student transitioning from BTS to DCG, you are pursuing a degree (university, business school, or engineering school) with a focus on Finance, Control, Audit, or Accounting.
- Experience with Odoo is a plus (internal training provided).
- Rigor and adherence to control procedures are essential, especially in a multi-entity environment with a sensitive payment cycle.
