Power Electronics Engineer

INA Solution; Torrance (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

INA Solution in Torrance, CA seeks a Senior Power Electronics Engineer with 3+ years of hands-on hardware design experience to own power systems for hypersonic flight vehicles. You will design PCBAs, include motor controllers and DC-DC converters, and own the full lifecycle from schematic through production integration.

You’ll work in a small elite avionics team, tackling high voltage/high current power systems and EMI/EMC considerations while collaborating across the hardware stack.

Qualifications

• 3+ years of experience in power electronics hardware design.
• Hands-on design ownership from schematic through bring-up, validation and production.

Responsibilities

• Design power electronics PCBAs including motor controllers, DC-DC converters, inverters and power distribution systems.
• Own the full lifecycle of hardware from schematic through bring-up, debug, validation and production integration.
• Define system-level requirements and own the end-to-end power system story in a single lead role.
• Work on high voltage and high current power systems for actuators, filtering and bus sizing for mission-critical avionics.
• Potentially support ground systems power electronics alongside flight hardware development.

Job description

We are looking for a Senior Power Electronics Engineer with 3+ years of experience to design and own power systems and power electronics boards for hypersonic flight vehicles. You'll join a small, elite avionics team where engineers personally make hardware work — not just manage requirements or provide oversight. This is a high-impact role where you'll own meaningful subsystems on the vehicle, from initial design through bring-up, debug, validation, and integration into production. Defense experience is not required — we value hands-on circuit design talent from aerospace, automotive, robotics, or any hardware-rich environment.

What will you be doing?

• Designing power electronics PCBAs including motor controllers, DC-DC converters, inverters, power switches, and power distribution systems for current and future flight vehicles
• Owning the full lifecycle of your hardware — from schematic design through bring-up, debug, validation, and production integration
• Defining your own requirements and figuring out the overall power system story in a system context (no separate systems engineers — you own it end-to-end)
• Working on high voltage and high current power systems for actuators, power filtering, and power bus sizing for mission-critical avionics
• Potentially supporting ground systems power electronics alongside flight hardware development
