Senior Embedded Software Engineer (Motor Control and Real:Time Systems)
Location: Reading with Hybrid WFH
KO2s client, a cutting:edge and rapidly scaling start:up based in Reading, is looking for a Senior Embedded Software Engineer to play a key role in developing next:generation motor drive and propulsion systems.
This is a high:impact opportunity to work on advanced embedded platforms at the intersection of real:time control, power electronics, and high:performance firmware, helping to shape both product direction and engineering culture from an early stage.
What Youll Do
Design and implement real:time embedded firmware for ESC controllers and next:generation motor drive systems, from initial architecture through to production release Develop and optimise motor control algorithms for BLDC motors, including field:oriented control, sensorless commutation, and current loop tuning Integrate sensors and implement feedback control systems for position, speed, and current regulation Own and implement communication stacks including CAN, UART, SPI, I2C, and DShot, and define telemetry interfaces Optimise firmware for performance, memory efficiency, and deterministic real:time behaviour on resource:constrained microcontrollers Collaborate closely with power electronics engineers to define hardware:firmware interfaces (gate drivers, current sensing, ADC configuration, protection logic) Lead firmware architecture decisions including RTOS selection, scheduling strategies, and platform abstraction Establish engineering best practices: version control, code reviews, testing frameworks, and CI/CD pipelines Conduct system:level validation including hardware:in:the:loop testing, dynamometer integration, and field trials
Required Skills and Experience
5+ years of hands:on experience in embedded C/C++ for real:time systems Proven experience in motor control, power electronics, or high:reliability embedded systems Experience in a technical lead or architect role, owning firmware from concept through production Strong expertise in RTOS (e.g. FreeRTOS, Zephyr), including scheduling, interrupts, and deterministic timing Experience implementing and debugging communication protocols (CAN, UART, SPI, I2C) Strong debugging skills using oscilloscopes, logic analysers, and hardware tools Proficiency with Git, CI/CD pipelines, unit testing, and modern development workflows
Preferred
Background in aerospace, defence, or UAV systems, particularly propulsion or ESC development Knowledge of advanced motor control techniques (FOC, sensorless control, space vector modulation) Familiarity with safety:critical standards (DO:178C, IEC 61508, MISRA C) Understanding of power electronics fundamentals (PWM, gate drivers, current sensing, thermal considerations
Whats on Offer
Opportunity to join a cutting:edge start:up at a pivotal growth stage Work on industry:leading technology with real:world impact Competitive salary, equity, and benefits package Flexible and hybrid working options A highly collaborative, ambitious, and technically driven culture.
