 * Motor control background: FOC, Space Vector Modulation, current loops
 * Sensor experience: Hall sensors, incremental encoders, absolute encoders

## Description

We need an embedded software engineer who can work across firmware and hardware. This is not a pure software role - the candidate will use oscilloscopes, read schematics, and debug board-level issues alongside writing C code., * Writing firmware in C for STM32 microcontrollers, particularly but not limited to motor controllers

 * End to end development: derive requirements, design/architect to satisfy requirements, implementation and verification.
 * Bringing up new hardware and debugging issues alongside motor-control and electrical engineers
 * Support mechanical team with new actuator design and verification
 * Example real task: Diagnosing why an Ethernet PHY reports CRC errors by analyzing R MII clock timing with an oscilloscope, reading the PHY datasheet, and identifying a board design issue.
