Détail du poste
INOCEL is a French company in the industrial energy transition, specialized in the design and commercialization of modular, freeemission 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: GENZ 300, GENZ 600, and GENZ 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 zerocarbon future, reinforcing our international vision and our role as a global leader in hydrogen energy.
We are seeking an experienced Senior Mechanical Designer to develop advanced thermal and energy systems operating in demanding high-temperature environments.
The successful candidate will be responsible for designing components and assemblies exposed to elevated temperatures (500-800°C), thermal gradients, pressure, and cyclic operating conditions. The role requires expertise in high-temperature materials, hot gas handling equipment, thermal management systems, and insulated structures.
While experience in SOFC (Solid Oxyde Fuel Cell) systems is highly desirable, candidates from industries such as power generation, gas turbines, combustion systems, internal combustion engines, industrial furnaces, hydrogen technologies, aerospace, and process equipment are encouraged to apply.
Key Responsibilities
Design and develop mechanical components and assemblies for high-temperature systems and Balance of Plant (BoP) equipment of a SOFC.
Create 3D CAD models, manufacturing drawings, BOMs, and technical documentation.
Design and integrate : Manifolds, flanges, bellows, and piping systems, Heat exchangers and recuperators, Burners, reformers, and hot gas handling equipment, Blowers and thermal management systems, Insulated enclosures and hot boxes.
Select materials suitable for operation between 500°C and 800°C, including stainless steels, nickel alloys (e.g., Inconel), insulation, refractory, and sealing materials.
Perform engineering calculations related to thermal expansion, structural integrity, pressure containment, and welded assemblies.
Support FEA and CFD activities when required.
Collaborate with systems, thermal, manufacturing, procurement, and testing teams.
Support prototype fabrication, testing, troubleshooting, and product industrialization.
Work with suppliers to optimize manufacturability, performance, and cost.
What we expect
Required Qualifications
Bachelor's degree in Mechanical Engineering or a related discipline.
Minimum 7 years of experience designing high-temperature equipment or thermal systems.
Proven experience with components such as manifolds, flanges, bellows, heat exchangers, burners, pressure-containing parts, and insulated enclosures.
Strong knowledge of:
Stainless steels and nickel-based alloys
High-temperature welded structures
Insulation and refractory systems
Thermal expansion management
Proficiency with SolidWorks, CATIA, Creo, NX, Inventor, or equivalent CAD tools.
Experience producing manufacturing drawings and GD&T documentation.
Familiarity with sheet metal, welded fabrications, machined parts, and high-temperature joining techniques.
Preferred Qualifications
Experience in fuel cells (SOFC), electrolysers (SOEC), hydrogen systems, gas turbines, combustion equipment, internal combustion engines, industrial furnaces, aerospace propulsion, power generation, or process industries.
Knowledge of ASME, PED, EN, API, or similar mechanical design standards.
Familiarity with FEA and CFD tools.
Experience with prototype development, testing, and Design for Manufacturing (DfM).
Key Competencies
Strong problem-solving and analytical skills.
Ability to work effectively in multidisciplinary teams.
Strong communication and technical documentation skills.
Hands-on approach to engineering development and testing.
What we offer
- A highimpact position within a fast-growing company
- An ambitious, supportive, and forwardlooking team
Compensation & Benefits
- An attractive compensation package defined according to experience.
- Health insurance
- Meal vouchers (€9.48/day)
