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.

Harmattan AI operates a group of nine entities across France, Switzerland, the US, UK, UAE, and Morocco.

As we continue to expand, the volume and complexity of intercompany transactions, including cost recharges, management fees, and stock recharges, are increasing significantly across all jurisdictions.

We are seeking an Intercompany Accountant to serve as the operational backbone of our group consolidation. While the accounting team manages daily bookkeeping, this individual will ensure that all intercompany transactions are tracked, invoiced, and reconciled each month for elimination purposes, guaranteeing our consolidated financials remain accurate, timely, and audit-ready.

• Ensure all flows are properly documented, consistently applied and aligned with the group's intercompany agreements

Transfer Pricing & Process Automation

• Drive the automation of IC reconciliations and intragroup invoicing workflows within Odoo, reducing manual tasks and improving the reliability and speed of the monthly close

Subsidiary Bookkeeping (transitional)

• Transitionally cover the bookkeeping of certain foreign subsidiaries (US, UK, UAE, Morocco) pending the hire of local Finance Managers, ensuring continuity and compliance with local requirements

Candidate Requirements

• 4 to 6 years of accounting experience, with significant exposure to intercompany transactions and multi-entity environments
