Job summary

Allocor.Tech in Virginia leads Taurus-class inverters for 4-quadrant FOC/SVPWM drives from ~20 V to 405 V and up to 32 kW, designed and tested in Virginia. The role owns the schematic-to-bring-up process and drives layout, EMI, and production testing to meet aerospace vibration and thermal requirements.

You will push the front end with precise current sensing, isolation, and high-dv/dt performance, with opportunities to scale to 800 V class and future high-power platforms.

Qualifications

• 5+ years on motor drives or HV power stages.
• 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.

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.

Job description

The role

Most motor-controller jobs are consumer ESCs or eighteen-month aerospace programs that never ship. This is neither.

The role

Most motor-controller jobs are consumer ESCs or eighteen-month aerospace programs that never ship. This is neither.

The role

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.

What You Will Do

• 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.

What You Bring

• 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.

Why Allocortech

Just over 50 people. Revenue has tripled. Founders from Kitty Hawk/Cora, Google, Rockwell Collins, and Lockheed. Small enough that your board flies. Serious enough that the architecture holds up in the air and on the water. American-made. Mountains out the window.

Important Information

This position may require prolonged periods of sitting, standing, walking, computer work, and occasional exposure to moderate levels of noise, dust, and fumes in production and lab areas.

Level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, and experience. Base salary is just one component of our total rewards package. Employees may receive equity opportunities and/or cash bonus, and have access to a robust benefits package including: top tier medical HMO, PPO & a 100% company-sponsored HSA plan option, dental and vision coverage, unlimited PTO, 11 paid holidays per year, flexible spending and dependent care savings accounts, paid parental leave, disability insurance, life insurance, and access to a 401(k) retirement plan with company match. Eligibility for benefits may vary based on employment status; please check with your recruiter for a comprehensive list of the benefits available for this role. Benefit programs are subject to change at the company’s discretion.
