Principal Electrical Engineer, High Voltage Power Electronics for Motor Drives

The posting, as Neon Aerospace wrote it

Aerospace is at a turning point — costs are rising, supply chains are strained, and old ways of building can’t keep up. At Neon Aero, we’re breaking that mold. We move fast, think big, and combine start-up agility with aerospace expertise to design, build, and scale aircraft in ways the industry has never seen. Our team leverages automation, AI-driven tools, and a fully connected digital backbone to accelerate innovation and reduce barriers to production.

Here, you won’t just take a job — you’ll help reinvent how the world flies. If you’re ready to solve complex problems, push technology further, and work alongside some of the brightest minds in aerospace, this is your chance to make a real impact.

Neon Aero is seeking a Principal Electrical Engineer in Irvine, California. The Principal Engineer, High Voltage Power Electronics for Motor Drives provides technical leadership in the architecture, design, and qualification of high voltage motor drives for aerospace and advanced mobility applications. This is a deeply hands-on role: the engineer personally develops architectures, block diagrams, schematics, and the analysis behind them, and owns the rationale for every major design decision across drives from 1 kW to 100 kW, on DC buses from 270 V to 800 V (up to 1000 V), powered by batteries in applications such as eVTOL and by turbogenerator systems. The role collaborates closely with motor control, embedded software, mechanical, thermal, manufacturing, and supply chain teams, and provides strong technical leadership, ownership, and mentoring of other engineers without direct people management responsibility.

Key Responsibilities

Architecture and Power Stage Design

• Own architecture and design of HV motor drives in two classes: 1 to 3 kW convection-cooled, and 3 to 100 kW liquid or forced-air cooled.
• Design inverter power stages for 270 V to 800 V buses (up to 1000 V): device selection (SiC, GaN, Si), gate drive, protection, and sensing.
• Develop PMSM drive hardware, applying motor control fundamentals to select feedback sensors, current sensing, switching frequency, and processors.
• Design input DM/CM filters and size DC link capacitors for ripple, stability, and lifetime.

EMI, Grounding, and Thermal Design

• Define shielding, grounding, and bonding for motors, cables, and enclosures to contain switching noise.
• Own thermal and EMI design for integrated motor and controller units in a single enclosure.
• Select components, processors, and HV connectors for high-vibration, extended-temperature aviation and defense environments.

Analysis, Validation, and Qualification

• Personally perform loss, thermal, stress, derating, insulation, EMI, and worst-case analyses.
• Develop schematics and review layouts for high dv/dt power stages (creepage, clearance, commutation loops, partial discharge).
• Lead bring-up, validation, and root cause investigations in the lab.
• Support DO-160 and MIL-STD-461 qualification and transition des

nt, high-reliability design experience (preferred, not required).

What We Value

• Engineers who have designed and shipped power electronics repeatedly.
• First-principles depth combined with practical, hands-on execution.
• Clear rationale behind every part selected and every design decision.
• High standards for reliability, manufacturability, and cost discipline.
• Technical leadership through mentoring, not formal authority, including growing EEs working on 28 V or 48 V motor drive controllers.
• Comfort operating in ambiguity while driving clarity for others.

Why Join Us

• Work alongside elite engineering talent and innovators from across aerospace and tech.
• Be part of a team moving faster than the industry standard.
• Shape solutions that are lower-cost, autonomous, and scalable — the future of aviation.
• Competitive compensation, including equity participation, growth opportunities, and full health benefits (health, vision, dental, 401(k)) designed to support you in and out of work.

This is the expected compensation range for this role. Final compensation will be based on role scope, experience, skills, internal equity and location. This role may also be eligible for bonus/equity/benefits, if applicable.
