Harmattan AI, a defense-tech company building autonomous defense systems, seeks an ERP Architect in Paris to own its Odoo ERP end to end — architecture, roadmap, manufacturing/MES rollout, integrations with PLM/CRM/finance, and managing external integrators — while staying hands-on in configuration and Python code.
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.
About the Role
As ERP Architect, you are the internal authority on Odoo, the system that runs Harmattan AI's industrial operations, from purchasing and inventory to manufacturing, quality and accounting. You own the architecture, the roadmap and the technical leadership of the ERP, managing external partners and teams from day one, so the system keeps pace as production scales. You work hands-on every day, from the shop floor to the data model, alongside manufacturing, supply chain and finance teams within Corporate Tooling.
Responsibilities
Define and own the target ERP architecture, module scope, customization rules and upgrade path.
Build and maintain the ERP roadmap, prioritizing initiatives with operations leads and leadership.
Deploy manufacturing and MES capabilities on Odoo, covering manufacturing orders, shop floor, quality and production ramp-up.
Own ERP master data quality across items, BOMs and suppliers.
Integrate Odoo with PLM, CRM and finance flows so items, BOMs and sales orders move reliably.
Extend Odoo accounting to every legal entity, in close collaboration with the finance team.
Run the Odoo integrator and freelance developers: write specs, steer sprints, accept deliveries and keep spend under control.
Stay hands-on in Odoo configuration, data fixes and code, while ensuring performance and reliability as usage grows.
Candidate 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 of 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 in 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.
We look forward to hearing how you can help shape the future of autonomous defense systems at Harmattan AI.
