Who We Are

Sparkmate is a tribe of fearless makers, building the future of steel through breakthrough industrial technology. We are developing the world’s first fully electrified pathway from ore to steel. Our mission is to transform the $1.5T global steel industry by eliminating fossil fuels from primary ironmaking and driving industrial decarbonization at scale.

We are looking for makers, builders, and innovators who are ready to turn this vision into reality.

About the Job

We are looking for a Mechanical Engineer with experience and a passion for prototyping, materials, and process development to support our research and development efforts in our factory. If you love both system engineering and mechanical design AND hands-on prototyping we want to hear from you! At Sparkmate, you’ll be part of a dynamic, flat-hierarchy, and fun team where you’ll work on real-world industrial challenges and help develop breakthrough low-temperature electrolysis technology.

This role is very hands-on, requiring strong mechanical design and integration abilities.

What You’ll Do

• Design and develop prototypes
• Assemble and troubleshoot experimental test setups, key cell components, and mechanical systems
• Operate CNC machines, 3D printers, and other prototyping tools to fabricate parts and iterate designs
• Critically analyze and interpret experimental data, providing insights and recommendations to the team
• Identify, refine, and innovate experimental tools and setups to meet evolving project need
• Manage relationships with vendors and manufacturers
• Manage the mechanical workshop
• Technical support for equipment installation and maintenance

What We’re Looking For

• Skilled in systems engineering and industrial process design
• Hands-on experience with manufacturing equipment and fabrication techniques
• Knowledge of materials selection for high-temperature, corrosive environments
• Ability to plan and execute projects independently and drive them to completion
• Proven ability to manage technical projects and communicate super clearly.
• Background in designing factory/industrial scale machineries is a plus

It's okay if you dont have it all. ;) Juniors and self-learners are welcome to apply - if you can demonstrate your ability to learn hard technical things faster than others.

Why Join Us?

• Be part of a young, dynamic, and international team of makers
• Work in a hands-on environment where your ideas and contributions truly matter
