Job description

Senior Embedded Software Engineer - Motor Control

Employment type: Full time

Position overview

Our client is an engineering-led technology company developing advanced embedded systems for demanding, high-reliability environments.

They are seeking an experienced motor-control firmware engineer to own the embedded software for a new microcontroller-based actuation subsystem. The role spans board-support software, real-time scheduling, peripheral integration, control state machines, protection behaviour, closed-loop control algorithms and integration with power electronics.

This is a hands-on individual-contributor position with end-to-end technical ownership, from early requirements and architecture through hardware bring-up, control tuning, verification, field support and continued improvement. You will work closely with embedded, electrical, power-electronics, controls and test engineers.

Responsibilities

• Own the motor-control software subsystem from initial requirements and architecture through production-ready implementation and ongoing support.
• Develop bare-metal and/or RTOS-based firmware for a microcontroller-based motor-control system.
• Create and maintain MCU board-support packages, low-level drivers and peripheral interfaces.
• Configure and debug timers, PWM generation, ADCs, interrupts, DMA, memory and communication peripherals.
• Design deterministic real-time software under strict latency, jitter, timing, memory and compute constraints.
• Develop control state machines, operating modes, fault handling, safe states and protection behaviour.
• Implement, tune and validate closed-loop motor-control algorithms.

• Support laboratory and field testing, production testing, failure investigation and corrective improvements.
• Improve build automation, continuous integration, static analysis, profiling and automated testing.
• Produce concise engineering documentation, contribute to technical reviews and mentor other engineers while remaining hands-on.

Required qualifications

• Approximately five or more years of relevant embedded-software experience is preferred; demonstrated technical depth and delivery experience are more important than a specific tenure.
• Deep practical expertise in bare-metal and/or RTOS-based microcontroller development for real hardware systems.
• Strong proficiency in at least one low-level systems-programming language, such as C or C++.
• Practical experience developing firmware for motor control, motion control, power electronics or a closely related real-time control system.
• Experience implementing deterministic software under latency, jitter, timing, memory and performance constraints.
• Strong understanding of real-time scheduling, timers, interrupts, DMA, concurrency, synchronisation, memory management and peripheral control.
