Who we are:  

Electra is reinventing ironmaking from the ground up with a breakthrough electrochemical technology that produces high purity clean iron and critical co-minerals. With two operating pilots in Boulder and a new demonstration facility underway in Jefferson County, we’re on track to reach commercial scale by the end of the decade. Backed by over $300 million and strategic partnerships with global leaders across mining, steel, and big tech, momentum is on our side.  Recognized by Fast Company as a Most Innovative Company and a Next Big Thing in Tech, and named one of TIME’s 100 Climate Leaders, we’re building a company shaping the future of industry. If you’re looking to make an impact and join a team that’s driven, focused, and scaling, we want to hear from you.

What you will do:  

The Mechanical Systems Engineer I supports the design, build, testing, and improvement of mechanical systems for Electra’s processing, material handling, and pilot or plant infrastructure. This is an early-career role focused on applying core mechanical engineering principles, producing quality technical work, collaborating across functions, and growing toward increased independence and ownership. 

Responsibilities include:

• Support the design of mechanical systems, equipment skids, and plant infrastructure under the guidance of senior engineers. 
• Develop and revise CAD models, drawings, layouts, and related engineering documentation. 
• Assist with equipment and component selection using design inputs, vendor information, and internal standards. 
• Support fabrication, assembly, integration, commissioning, and testing activities with technicians, contractors, and cross-functional teams. 
• Troubleshoot mechanical systems and equipment with appropriate guidance and escalation. 
• Document design decisions, test results, observations, and lessons learned clearly and accurately. 
• Coordinate with process, automation, electrical, operations, and project teams to complete assigned work. 
• Engage with internal customers and suppliers to gather inputs and to support execution. 
• Follow engineering standards, templates, and document control requirements. 
• Work safely and comply with all health, safety, environmental, and quality requirements. 
• Actively build technical capability through feedback, training, and hands-on experience. 
• Perform other duties as assigned. 

What we need you to bring to the team:   

• Bachelor’s degree in Mechanical Engineering, Electromechanical Engineering, or a closely related engineering discipline. 
• 0–2 years of relevant experience in mechanical engineering, process equipment, manufacturing, pilot plants, or industrial systems.
• Foundational knowledge of mechanical engineering principles, including fluid systems, heat transfer, mechanical equipment, and system integration. 
• Ability to apply engineering fundamentals to routine problems with guidance. 
• Ability to document, communicate, and apply lessons learned from testing or project work. 
• Ability to produce organized and accurate engineering work products, including models, drawings, calculations, and test records. 
• Familiarity with CAD tools for 3D modeling and drawing development. 
• Strong written and verbal communication skills and the ability to work effectively across teams. 
• Ability to learn quickly, follow engineering standards, and manage assigned work within a defined scope. 
• Willingness to support hands-on equipment builds, testing, and troubleshooting in lab, pilot, or plant environments. 
• Proficiency with, or ability to quickly learn, Microsoft Office tools including Word, Excel, PowerPoint, Outlook, OneDrive, and SharePoint.
