Mechanical Design Engineering Lead - Electrolyzer Systems

A growth-stage climate infrastructure startup building and scaling electrolyzer systems for carbon removal and green hydrogen production. Having successfully deployed large-scale pilot systems, the company is now transitioning into commercial manufacturing and is establishing its production capability in India. The current phase focuses on industrialising electrolyzer hardware - driving design-for-manufacturing (DFM), cost reduction, supplier development, and scalable production of complex, multi-material electrochemical systems, with a strong focus on translating prototypes into manufacturable, scalable designs. This is a hands-on engineering and manufacturing build-out environment, particularly relevant and suited for candidates with experience in electrolyzer manufacturing, fuel cells, hydrogen systems, or mechanical design of chemical/process equipment. Candidates from adjacent industries with strong design-for-manufacturing experience are also encouraged to apply.

Mechanical Design Engineering Lead - Electrolyzer Systems

Based in Mumbai

About the role

This role focuses on leading designing and developing the physical hardware of next-generation electrolyzer systems, translating early-stage lab-scale prototypes into robust, scalable, and manufacturable products. You will work at the intersection of mechanical design and real-world deployment, collaborating closely with cross-functional teams - including chemical and electrochemical engineers - to bring complex systems from concept through to production. The position requires a hands-on, technically strong individual who can iterate rapidly, optimize designs for performance and cost, and operate effectively in a fast-paced, experimental environment with high levels of ambiguity.

Responsibilities:

• Lead the design and development of mechanical components and assemblies for advanced hardware systems
• Translate early-stage prototypes into scalable, functional, and manufacturable designs
• Develop and refine prototypes through iterative design cycles, from proof-of-concept to production-ready solutions
• Optimize designs for performance, manufacturability (DFM), ease of assembly, and cost efficiency
• Conduct testing using experimental and simulation methods to validate performance under various conditions
• Analyse test results and collaborate with cross-functional teams to improve system design
• Prepare detailed engineering documentation and specifications for manufacturing and production
• Work closely with suppliers and manufacturers to ensure successful execution of designs
• Contribute to the development of next-generation systems through continuous innovation and improvement
• Act as a foundational/pioneer engineering hire, helping establish engineering standards, design workflows, and technical best practices as the team scales
• Provide technical guidance and mentorship to future engineers and cross-functional team members as the engineering function expands

Requirements:

• Degree in Mechanical Engineering, Industrial Design, or a related field
• Minimum 5 years of experience in mechanical design of parts and assemblies
• Experience working with suppliers and manufacturers to bring designs into production
• Strong knowledge of materials, including metals, polymers, and common alloys
• Familiarity with a range of manufacturing and prototyping processes
• Proficiency in CAD and CAM tools
• Strong understanding of engineering fundamentals and mechanics of materials
• Ability to operate hands-on in a fast-paced, iterative development environment
• Proactive, self-driven mindset with the ability to solve open-ended problems

Nice-to-haves:

• Demonstrated potential to grow into a technical leadership role within a scaling engineering organisation
• Experience designing parts for chemical processes
• Experience with power electronics
• Modelling experience (FEA, CFD)
• Passion for carbon management solutions
• Comfort with working in cross-functional teams across jurisdictions

Only shortlisted applicants will be contacted.
