As ERP Architect, you will be the internal authority on Odoo, the system running Harmattan AI's industrial operations—from purchasing and inventory to manufacturing, quality, and accounting. You own the architecture, roadmap, and technical leadership of the ERP, managing external partners and teams from day one to ensure the system scales with production.
Key responsibilities include:

- Integrate Odoo with PLM, CRM, and finance flows to ensure reliable data movement
- Extend Odoo accounting to every legal entity in collaboration with the finance team
- Manage Odoo integrators and freelance developers: write specs, steer sprints, accept deliveries, and control spend
- Stay hands-on in Odoo configuration, data fixes, and code while ensuring performance and reliability as usage grows
You will work alongside manufacturing, supply chain, and finance teams within Corporate Tooling, operating in a demanding environment where rigor, ownership, and execution are expected.
REQUIREMENTS:
- 6+ years of experience in ERP; Odoo experience is a strong plus
- Track record of owning an ERP end-to-end in an industrial company, or leading Odoo projects at an integrator
- Solid manufacturing and supply chain knowledge: MRP, BOMs, routings, quality, and inventory
- Ability to configure, fix, and build yourself—from Odoo setup and data to code in Python
- Strong technical leader and pragmatic owner, experienced in managing partners and teams and making clear trade-offs
- Understanding of what AI makes possible, and strong motivation to upgrade ERPs with it
- Engineering degree appreciated, though proven professional experience matters more
- Fluency in English required; French is a plus
