About EH Group Engineering
EHG is developing cutting-edge fuel cell technology for heavy duty mobility and large-scale stationary power applications. Our uniquely redesigned product is a significantly more compact fuel cell with high power density and lower costs of production. Faced with the challenges of climate change and the transition to a decentralised energy system, EHG seeks to provide high performance and cost-effective fuel cell solutions to our clients and partners.
To help achieve our vision of a decarbonised future we are seeking Mechanical Engineers to design components and assemblies for our compact, high power density fuel cell products.
This role requires full-time, on-site presence at our Nyon, Switzerland office. We're not able to offer remote or hybrid arrangements, so candidates should be prepared to relocate.
Key Responsibilities:
• Design mechanical components, modules and assemblies for fuel cell stacks and systems
• Produce 3D models, detailed drawings and tolerancing (GD&T)
• Apply design-for-manufacture and design-for-assembly principles
• Support prototyping, build and validation of designs
• Work with suppliers on component manufacture and tooling
• Maintain BOMs, drawings and engineering changes in PLM
• Collaborate with simulation, test, electrical and process engineering
Skills and Experience Required:
• BSc/MSc in mechanical engineering is mandatory
• Minimum 3–5 years of mechanical design experience in a complex hardware engineering environment, with direct experience in fuel cell stacks, electrolyzers, high-voltage battery modules, powertrains, or complex thermal systems.
• Proficiency with 3D CAD (ex. SolidWorks) and in-depth understanding of GD&T
• Understanding of DFM/DFA and common manufacturing processes
• Knowledge of sealing, thermofluidic, thermal or structural design is a plus
• Team player able to work autonomously with internal and external experts
• Excellent spoken and written English is mandatory, French is a plus
