Senior Motor-Generator Engineer

Antares•Los Angeles, CA

10d•$145,000 - $220,000

About The Position

As a Senior Motor-Generator Engineer, you will own the design and development of high-speed motor-generator units (MGUs) for Antares nuclear reactors. You will serve as the primary technical interface with electric-machine suppliers while helping build Antares’ internal capability to design, analyze, manufacture, and test stators and permanent-magnet rotors. You will collaborate with electrical, turbomachinery, mechanical design, manufacturing, and test engineers to integrate MGUs into power conversion systems. The role calls for experience designing electric motors or generators and strong knowledge of electromagnetic design, materials, manufacturing processes, and hardware testing. You will make engineering tradeoffs across electrical performance, mechanical integrity, thermal limits, reliability, manufacturability, cost, and schedule. The position may be leveled as Senior Engineer or Staff Engineer during the interview process; the stated salary ranges are $145,000–$190,000 for Senior Engineer and $155,000–$220,000 for Staff Engineer. Occasional weekend or long-hour work may be needed to support hardware development milestones, and periodic travel to supplier and test facilities is required. Applicants must meet the stated U.S. Government export-control eligibility requirements or be eligible to obtain the required authorizations.

Requirements

Bachelor's degree in Electrical Engineering, Mechanical Engineering, or a related engineering discipline.
At least 5 years of professional experience designing and developing electric motors, generators, or similar electric machines.
Experience performing electromagnetic design and analysis of electric machines, including magnetic circuits, winding configurations, torque production, voltage characteristics, and losses.
Experience with electromagnetic analysis tools such as ANSYS Maxwell, Motor-CAD, JMAG, or equivalent.
Working knowledge of electric-machine materials and manufacturing processes, including electrical steel laminations, windings, insulation systems, and permanent magnets.
Experience developing electric-machine hardware through manufacturing, assembly, and testing.
Experience making engineering tradeoffs involving performance, reliability, manufacturability, cost, and schedule.
Demonstrated ability to communicate technical information clearly.
Flexibility to support hardware development milestones, including occasional weekend or long-hour pushes.
Ability to travel periodically to supplier and test facilities.
Must be a U.S. citizen or national, U.S. lawful permanent resident, qualifying refugee or asylee, or eligible to obtain required U.S. Department of State authorizations, to conform to U.S. Government export regulations.
