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.

Candidate Requirements

• 5+ years of proven experience in an HR Generalist or HRBP role, with at least 2 years on an industrial or manufacturing site.

• Demonstrated ability to operate as the sole HR on a site — autonomous, structured, and reliable.

• Solid working knowledge of French Labour Code; experience with Metal industry collective agreement is a plus.

• Hands-on experience with disciplinary procedures, absence management, and first-level payroll.

• Proficiency with an HRIS (HiBob a plus) and a scheduling tool (Skello or equivalent).

• Strong prioritisation skills: able to manage high volume and competing demands in a fast-paced environment.

• Pragmatic business partner mindset: works with the business to find solutions, not obstacles.

• Excellent interpersonal skills; comfortable and credible with non-managerial, shop floor profiles.

• Ability to handle sensitive and confidential information with discretion.

• Full professional fluency in both French and English (written and verbal).

We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
