Senior Embedded Software Engineer (Motor Control & Real-Time Systems) Location: Reading with Hybrid WFH Salary: Up to £90,000 DOE KO2’s 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 You’ll 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) What’s 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.
