Staff Technical Program Manager

Electrical Engineer

• Design critical electrical systems that enable key functions and ever-expanding features of Mainspring’s linear generator
• Work on a wide variety of subsystems and components, including (in no particular order) high voltage batteries, grid-tie inverters, capacitor banks, motor drives, low and high voltage power distribution, safety controllers, and more
• Become an expert on the linear generator electrical system. This involves the hardware designs and the system-level controls that bring the hardware to life
• Be called upon to troubleshoot our most complex system-level problems, and be able to breakdown abstract system-level symptoms to be able to identify which subsystem is the cause of the problem
• Regularly blur the line between operating as an electrical design engineer and a systems engineer. This will involve activities such as defining electrical system requirements, allocating requirements to subsystems, analyzing trade-offs between subsystems, and leading the team to develop robust verification plans
