Senior FOC Firmware Engineer - Real-Time Motor Control

Allocor Tech; Crozet (VA); On-site; USD 110,000 - 170,000; Full time

Job summary

Allocor.tech is seeking an experienced embedded firmware engineer to push Taurus controller FOC on PMSM/BLDC for aerospace and marine applications. You will own torque loops, calibrate on real hardware, and extend the allocore C++ SDK for drop-in outer loops.

You will develop production-grade firmware on Cortex-M targets, implement robust sensorless techniques, and help bring up new hardware with rigorous testing and validation activities.

Qualifications

• 5+ years embedded motor-control firmware with FOC on PMSM/BLDC.
• Discrete-time control, transforms, SVPWM, current-loop bandwidth.
• Production C/C++ on bare metal or thin RTOS; read scopes and map files.
• CAN (2.0/FD), RS-485, encoder/Hall interfaces.
• Bonus: sensorless observers, SiC timing, MATLAB/Simulink-to-embedded, functional safety.

Responsibilities

• Implement and harden FOC: Clarke/Park, current and speed loops, field weakening, overmodulation, dead-time, observers.
• Write real-time C/C++ on Cortex-M and similar: PWM, ADC, DMA, isolated comms.
• Own sensored and sensorless paths, calibration, and protection for flight and salt water.
• Extend the allocore SDK so customers can drop in outer loops without touching your inner loop.
• Bring up new hardware with the EE and build the test story: HIL, scripted dyno, regression, production load.
