Job summary

Allocor.Tech in the United States seeks an experienced embedded firmware engineer to advance Field-Oriented Control for Taurus drivers. You will implement and harden FOC on PMSM/BLDC, extend the allocore C++ SDK, and bring up new hardware with fast control loops, HIL testing, and robust safety.

You will work on Cortex-M devices with C/C++, PWM, ADC, DMA, CAN/RS-485, and sensorless paths. A production-grade mindset is required to survive flight and salt water, with responsibility from calibration

Qualifications

• 5+ years embedded motor-control firmware experience.
• FOC on PMSM/BLDC is required.
• Discrete-time control, SVPWM, current-loop bandwidth.
• CAN/RS-485, encoder/Hall interfaces experience.
• Production C/C++ on bare metal or a thin RTOS.

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 (STM32-class and beyond): PWM, ADC, DMA, isolated comms.
• Own sensored and sensorless paths, calibration, and protection that survive 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.
