Harmattan AI is a next-generation defense prime building autonomous and scalable defense systems. Following a $200M Series B at a $1.4B valuation, the company is expanding teams to deliver mission-critical systems to allied forces.
As Accounts Payable Specialist, you will own the full supplier-to-payment cycle for Harmattan AI's entities. This is not a transactional role—you will build and improve AP processes as the company scales across multiple entities and geographies. Working closely with Finance, Procurement, and cost center managers, you ensure supplier payments remain reliable and controls remain strong.
Key responsibilities include:
- Owning the complete supplier-to-payment workflow: invoice receipt, coding, approval, and payment execution
- Performing three-way matching and resolving discrepancies with Procurement and Operations
- Preparing and validating payment runs (SEPA and international) aligned with due dates and cash planning
- Reconciling supplier accounts and investigating unallocated payments or disputes
- Managing supplier inquiries on payment status and verifying bank detail changes before updates
- Improving invoice capture, approval workflows, and reporting; driving AP automation initiatives
- Strengthening internal controls and fraud prevention across the AP process
- Maintaining AP records and procedures to support audits and French accounting compliance
You will operate in a demanding environment where rigor, ownership, and execution are expected. The role offers the opportunity to shape processes at a high-growth, well-funded defense technology company.
REQUIREMENTS:
- 2 to 4 years of accounts payable experience, ideally in industrial or high-growth environments
- Solid command of the full AP cycle: invoice processing, matching, payment runs, and supplier reconciliations
- Strong knowledge of French accounting rules and VAT, including intra-EU and import transactions
- Proficiency with ERP or accounting systems; advanced Excel skills
- Familiarity with AP automation tools (preferred)
- Experience with multi-entity and multi-currency accounting (preferred)
- Demonstrated rigor, accuracy, and strong internal control mindset
- Ability to work autonomously with a process improvement mindset; ability to spot inefficiencies, document procedures, and propose improvements
- Collaborative, service-oriented approach with internal stakeholders and suppliers
- Fluent French and professional English
