Description du poste

About The Role

As we scale our production and supply chain capabilities, we are looking for Operational Buyers to join our Supply Chain team. This role sits at the interface between planning and procurement — you will be the execution engine ensuring components are on time, data is accurate, and suppliers are held accountable.

Responsibilities

• Translate production requirements into supplier purchase orders, in close coordination with Supply Planners.
• Create, issue and track purchase orders (POs) from placement to delivery within Odoo.
• Monitor deliveries proactively and anticipate supply risks — follow up with suppliers, elevate when needed.
• Negotiate operational conditions with existing suppliers: lead times, MOQ, delivery terms.
• Maintain accurate master data in the ERP (lead times, MOQ, pricing) — you own data quality for your perimeter.
• Coordinate with planning, project and operations teams to ensure component availability.
• Support new supplier onboarding in collaboration with category buyers.

Candidate Requirements

• 3 to 5 years of experience in operational purchasing or procurement, ideally in an industrial or high-tech environment.
• Proficiency with an ERP system — Odoo preferred, or equivalent (SAP, Oracle, Dynamics).
• Strong attention to detail and rigor in data management and order tracking.
• Ability to work in an agile environment and manage multiple priorities simultaneously.
• Good communication skills — regular interface with suppliers and internal stakeholders.
• Fluent in French and English (international environment).
• Experience in defense, aeronautics or industrial electronics is a plus.

Benefits

A key operational role in a fast-growing defense startup, with direct impact on product availability.

A structured Supply Chain team with processes actively being built — you will contribute to shaping them.

A fast‑paced environment with short cycles and close collaboration across engineering, projects and operations.

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