About Us

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.

Responsibilities

HR Operations & Personnel Administration

Manage individual employee situations end-to-end: disciplinary procedures, conflict resolution, and sensitive cases in compliance with French Labour Code.

Handle personnel administration: contracts, amendments, employee files, employment certificates, and all HR documentation for on-site employees.

Prepare variable payroll inputs (absences, overtime, bonuses, new hires, leavers) and liaise with the payroll provider; cross-check payslips before each payroll close.

Track and manage absences and leave requests via HiBob; validate hours in Skello prior to payroll.

Ensure compliance with applicable collective agreement (Métallurgie) and all legal HR obligations as headcount scales.

Maintain accurate employee records in the HRIS and ensure proper archiving of all HR documents.

Onboarding/Offboarding Support

Design and deploy a scalable onboarding process adapted to the plant environment; ensure each new joiner has a structured, warm, and efficient integration from day one.

Manage the interface with agencies for the temporary workforce (contracts, scheduling, absence replacements).

Handle offboarding with clarity and proper handover of information.

Manager & Employee Partnership

Act as the single HR point of contact for the site: be a visible, accessible, and trusted presence on the shop floor every day.

Support the Site Director and line managers with concrete, operational HR answers — close to production, close to the teams.

Coach managers on HR tool usage (HiBob, Skello) and best practices.

Contribute to a healthy working environment by addressing employee concerns promptly and pragmatically.

HR Processes & Reporting

Build and improve on-site HR processes; document them and make them replicable for future sites.

Contribute to HR dashboards and reporting (headcount, absenteeism, turnover, training indicators).

Coordinate training plans: register employees, manage logistics, track budget and completion.

Health & Safety

Participate in risk assessment (DUERP) and workplace prevention actions along with the HSE Manager.

Track workplace accidents and near-misses; ensure proper reporting and corrective actions.

Office Management

Support office management structuration and execution during the rampup: PPE, consumables.
