Description du poste

INOCEL is a French company in the industrial energy transition, specialized in the design and commercialization of modular, free‑emission hydrogen generators. Our solutions deliver continuous and reliable power to critical industries - from data centers to construction sites and remote locations - without compromising performance.

Backed by more than 25 years of research on hydrogen fuel cells, we offer modular generators for both stationary and mobile applications: GEN‑Z 300, GEN‑Z 600, and GEN‑Z 1300. Beyond equipment, INOCEL provides turnkey solutions, including integration, maintenance, and advanced monitoring to ensure reliability, performance, and durability.

With industrial production in Belfort and R&D centers in Grenoble and Cannes, INOCEL combines innovation, technological expertise, and positive environmental impact. Our scalable and silent solutions enable partners worldwide to transition toward a zero‑carbon future, reinforcing our international vision and our role as a global leader in hydrogen energy.

Today, we are strengthening our expertise and recruiting a Mechanical Design Engineer W/M

About The Role

As part of our R&D Engineering team, you will contribute to the design and development of the Power Conversion Unit (PCU) for next-generation Fuel Cell systems.

The PCU is a complex mechatronic system integrating energy storage, power electronics, cooling systems, structural components, electrical interfaces, instrumentation, and control hardware into a robust stationary power generation solution.

We are looking for a Mechanical Design Engineer with experience in the development of complex industrial equipment, particularly in generator sets (gensets), stationary power systems, industrial machinery, power conversion equipment, or similar electromechanical products.

Working in a multidisciplinary environment, you will collaborate closely with electrical, thermal, controls, manufacturing, testing, procurement, and quality teams to deliver reliable, manufacturable, and cost-effective products from concept through industrialization.

Key Responsibilities

• Design and develop the mechanical architecture of the Power Conversion Unit throughout the product development lifecycle.
• Create 3D CAD models, manufacturing drawings, Bills of Materials (BOM), and engineering documentation.
• Design structural components, sheet metal assemblies, enclosures, cooling systems, mounting structures, cable management, and mechanical interfaces.
• Ensure seamless mechanical integration with electrical, thermal, and control subsystems.
• Perform mechanical calculations, tolerance stack‑up analyses, and support structural and thermal simulations (FEA).
• Prepare technical specifications, participate in design reviews, and support DFMEA activities.
• Collaborate with suppliers on component development, technical validation, and manufacturability.
• Support prototype assembly, testing, root‑cause analysis, and implementation of design improvements.
• Apply Design for Manufacturing (DFM) and Design for Assembly (DFA) principles to optimize product quality, cost, and serviceability.

Profile

Education

• Master's degree in Mechanical Engineering, Mechatronics, Product Design, or a related engineering discipline.

Experience

• 4–8 years of experience in mechanical design of complex industrial or electromechanical systems.
• Experience in stationary power generation, gensets, industrial equipment, electrical enclosures, HVAC, rail, marine, off‑highway, or energy systems is highly desirable.
• Experience working in a multidisciplinary product development environment is expected.
• Fuel cell or hydrogen experience is considered a plus.

Technical Skills

• Strong mechanical design and product integration capabilities.
• Proficiency with SolidWorks, CATIA, Creo, or equivalent 3D CAD software.
• Good understanding of sheet metal, welded structures, machined parts, GD&T, tolerance analysis, and manufacturing processes.
• Familiarity with PLM/PDM systems; experience with FEA tools is an advantage.

Personal Skills

• Strong analytical and problem‑solving skills with a hands‑on engineering mindset.
• Autonomous, organized, and proactive, with excellent communication and collaboration abilities.
• Comfortable working in a fast‑paced, innovation‑driven environment.
• Fluent English is required; French is a plus.

What We Offer

• A high‑impact position within a fast - growing company
• A scope of responsibilities that will expand as the company grows
• An ambitious, supportive, and forward‑looking team
