Mechanical Systems Engineer I

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.

• • 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.

What we want you to bring to the team

• • Relevant internship, co-op, research, capstone, lab, or early industry experience in mechanical design, fabrication, testing, or process systems.

• • Exposure to engineering documentation such as P&IDs, general arrangements, assembly drawings, wiring diagrams, control panel layouts, or equipment specifications.

• • Exposure to operations, maintenance, commissioning, or field installation in industrial or pilot environments.

• • Experience in an R&D, pilot plant, startup, or fast-paced technical environment.

• • Familiarity with pumps, valves, piping systems, heat exchangers, tanks, material handling equipment, or other industrial mechanical systems

Compensation

• The anticipated starting pay range for this position is $75,000 to $85,000 and may be more or less depending upon skills, experience, and education.
