Full Job Description
WHO YOU ARE:
Astro Mechanica is seeking a Power Electronics Controls Engineer to join our growing team. The ideal candidate is a controls engineer at heart who is excited to own the control of the power electronics that drive our propulsion: an 800-volt system delivering 1 megawatt of electrical power to the motors on our Gen 5 engine. You will bring that same controls expertise to our ground power systems, where large turbines and generators must be governed and kept in sync. You will work on a small, tight team alongside a mechanical engineer focused on the liquid-cooled inverter enclosure and an electrical engineer focused on the inverter hardware. Your work at Astro Mechanica will have a direct impact on the configuration and performance of our engine.
WHAT YOU'LL DO:
Design, implement, and tune control systems for the inverters that drive the motors on our 800 V, 1 MW propulsion system
Develop controls for related power electronics, including DC-DC converters and motor controllers
Own bus control and governor design for our electrical systems
Support ground power by synchronizing and governing coupled systems, such as a 13 MW turbine and generator or a connection to grid power
Take systems from concept through hardware, validating control performance on real equipment
Work closely with mechanical, electrical, and propulsion engineers to bring the inverter from design through test
WHAT WE'RE LOOKING FOR:
Bachelor's degree in Electrical Engineering or a related field and 5+ years of experience in power electronics controls
Hands-on experience designing controls for power electronic systems, such as DC-DC converters, motor controllers, or inverters
Proven track record of building one of these systems, not just modeling or analyzing it
Working knowledge of motor control, including Field Oriented Control (FOC) and related techniques
Experience with three-phase electrical systems and machines, such as permanent magnet motors
Experience with high-voltage, high-power-density systems, such as EV traction or eVTOL propulsion
Inverter design experience is a plus
Experience synchronizing and governing coupled, complex power systems, such as multiple inverters, or turbines and generators for bus-tied or grid-tied power, is a plus
PERKS & BENEFITS:
Comprehensive medical, dental, and vision insurance, including Flexible Spending Accounts (FSA)
401(k) program and transparent stock option plan
Self-managed and flexible time-off policy, including PTO, paid holidays, and sick time
Flexible work environment
ADDITIONAL INFORMATION:
At Astro Mechanica, we highly value in-office work to foster collaboration and strengthen our company culture. We consider working in the office five days a week an essential part of the employee's role.
