Job description

Overview

Electra is reinventing ironmaking from the ground up with a breakthrough electrochemical technology that produces high purity clean iron and critical co‑mining. 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.

Role

Mechanical Systems Engineer II – responsible for designing and supporting mechanical systems with ownership of defined components or subsystems within larger process systems across lab, pilot, demonstration, and future commercial facilities. Work closely with a highly collaborative team of process, automation, electrical, and operations engineers to turn first‑of‑a‑kind concepts into safe, practical, and scalable plant solutions.

Responsibilities

• Design and support mechanical systems and equipment within defined subsystems for Electra’s process, utility, slurry, solid handling, and plant infrastructure systems.
• Develop layouts, general arrangements, piping details, equipment lists, and drawing packages for skids, pilot systems, plant tie‑ins, and facility projects.
• Independently select and specify mechanical equipment within assigned scope such as pumps, tanks, valves, piping, filters, heat exchangers, supports, and material handling equipment.
• Translate process flow diagrams, P&IDs, and test objectives into practical mechanical designs for installation, operation, and scale‑up.
• Partner with process, automation, electrical, structural, operations, maintenance, EHS, technicians, vendors, and contractors to deliver integrated plant solutions.
• Lead and support fabrication, installation, commissioning, troubleshooting, and field updates within defined scope for pilot and plant equipment.
• Review vendor quotes, technical submittals, and fabrication details to ensure selected solutions meet project needs and operating requirements.
• Create and maintain 3D models, mechanical drawings, and controlled design documentation using CAD and standard engineering tools.
• Contribute to design reviews, hazard reviews, lessons learned, and continuous improvement of mechanical design standards and practices.
• Follow all workplace health, safety, and environmental procedures and perform other duties as assigned.

Qualifications

• Bachelor’s degree in mechanical, electromechanical, or related engineering discipline.
• 2+ years of mechanical engineering experience in industrial process, pilot plant, manufacturing, or plant infrastructure environments.
• Experience translating process requirements into mechanical equipment selections, piping layouts, skid designs, and engineering documentation.
• Working knowledge of pumps, valves, tanks, piping, filters, heat transfer equipment, supports, utility systems, and solids or slurry handling equipment.
• Ability to use P&IDs, process descriptions, test plans, and layout constraints to develop practical mechanical designs.
• Experience supporting fabrication, installation, commissioning, troubleshooting, or field modifications for process equipment.
• Proficiency with CAD and engineering documentation tools.
• Strong collaboration, communication, and organizational skills.
• Ability to manage multiple priorities in a fast‑paced environment with increasing independence.

Preferred Qualifications

• Experience in electrochemical, hydrometallurgical, chemical process, metallurgical, mining, or other industrial plant environments.
• Familiarity with slurry transport, solution handling, filtration, solids processing, reagent distribution, or pilot plant utility systems.
• Experience with materials selection and equipment specification for corrosive, abrasive, aqueous, or solids‑laden service.
• Ability to read P&IDs, isometrics, general arrangements, piping layouts, and related engineering drawings.
• Experience supporting design reviews, HAZOP or similar hazard reviews, commissioning, and startup activities.
• Familiarity with applicable codes, standards, and good engineering practices for industrial mechanical design.
• Experience in a startup, scale‑up, or first‑of‑a‑kind process technology environment.

Compensation

• The anticipated starting pay range for this position is $85,000 to $105,000 and may be more or less depending upon skills, experience, and education.

Benefits

• 100% paid premiums across all medical, dental, vision, telemedicine, short‑term disability, long‑term disability, and basic life insurance plans.
• $1,800 in annual employer HSA contributions (health savings account).
• 12 weeks of paid parental leave.
• 401(k) with up to 5% matching contributions which vest 100% on day one.
• Eligibility for incentive stock options.
