A Snapshot of Your Day 
As a Development Engineer, you will shape the future of green hydrogen by designing high-performance PEM or AEM electrolysis stacks. Your day will involve transforming concepts into scalable, production-ready components, collaborating with cross-functional teams, and supporting integration at our state-of-the-art Gigafactory in Berlin. You’ll work alongside experts in electrochemistry, simulation, manufacturing, and procurement to drive innovation and deliver robust, cost-effective solutions. Our inclusive and quality-driven culture empowers you to grow your skills and make a real impact on the energy transition.
How You’ll Make an Impact 

• Design, develop, and release mechanical components and drawings for PEM and AEM electrolysis stacks, ensuring compliance with quality and project standards
• Lead the conceptualization, simulation, and optimization of stack components from idea to implementation
• Act as a key technical interface to manufacturing and quality teams, supporting seamless production processes and providing on-site support at our Gigafactory in Berlin
• Manage product data and documentation, enabling efficient transfer to future product generations
• Optimize designs through "design to cost" initiatives, balancing performance, scalability, and cost
• Collaborate across disciplines—electrochemistry, system engineering, and procurement—to foster innovation and deliver high-performance, cost-effective solutions

What You Bring

• A Bachelor’s degree in Mechanical Engineering or a related field is required, with a strong preference for advanced degrees such as a Master’s or Ph.D
• Midterm experience in mechanical design within high-performance system sectors, ideally with direct exposure to hydrogen or renewable energy technologies and development procedure in general
• Proven proficiency in 3D-CAD & 2D-CAD software (preferably NX) and hands-on experience with FEA/structural simulations and calculations (preferably using ANSYS Workbench)
• A deep understanding of electrolysis processes, particularly PEM or AEM, including design principles and manufacturing practices
• Fluency in English and German is essential for effective collaboration in a global and diverse work environment
• Experience leading cross-functional teams with responsibility for budget, resources, and timelines as well as strong communication skills, a proactive mindset, and the ability to thrive in interdisciplinary teams
