Senior Motor Controller Electrical Engineer at allocortech inc. in Crozet, Virginia

Job description

• Most motor-controller jobs are consumer ESCs or eighteen-month aerospace programs that never ship. This is neither.
• You will own Taurus-class inverters — four-quadrant FOC/SVPWM drives from ~20 V to 405 V and up to 32 kW — that already fly on eVTOL, hybrid cargo aircraft, and electric hydrofoils. Designed, assembled, and tested in Virginia. Lead times in weeks. Your schematic leaves the building.

Responsibilities

• Own schematic-to-bring-up: SiC/Si MOSFET inverters, gate drive, isolated sensing, DC link, protection, thermal path.
• Design for 80–400+ V, tens of kW peak, four-quadrant regen, IP67 packaging, and aerospace vibration/thermal environments.
• Get the analog front end right — current sense, offset, bandwidth, isolation, ADC integrity — because FOC depends on it.
• Drive layout review, proto, EMI/thermal debug, and production test.
• Help stand up the next voltage and power class, including 800 V-class work already in motion.

Requirements

• 5+ years on motor drives or HV power stages — not point-of-load bucks.
• BLDC/PMSM inverter topologies, gate drivers, current sensing, snubbers, creepage/clearance, magnetics.
• Schematic and layout judgment on mixed-signal, high-dv/dt boards (Altium or equivalent).
• Lab fluency: scopes, current probes, power analyzers, thermal cameras, dyno or equivalent.
• Bonus: SiC, DO-160, CAN, isolated comms, hybrid-electric or eVTOL programs.
