About the Role

Our client, an engineering organisation developing advanced power conversion and electrification technologies, is seeking an Embedded Software Engineer to support firmware development for high-power converter systems.

In this role, you will work closely with power electronics, hardware, and systems engineering teams to design and implement embedded control software for real-time power electronics applications.

Key Responsibilities

• Develop and maintain embedded firmware for real-time power electronics control systems operating in safety-critical environments
• Implement control algorithms for DC-DC converters, AC-DC converters, and inverter systems, including modulation, protection mechanisms, and state management
• Support integration of firmware with FPGA-based control and sensing architectures
• Translate control system requirements into efficient and testable firmware implementations
• Perform board bring-up and firmware validation on bare-metal embedded targets
• Contribute to unit testing, integration testing, and automated build pipelines
• Support verification, validation, and commissioning activities at both laboratory and system levels
• Produce and maintain technical documentation covering firmware design, interfaces, and known limitations
• Strong proficiency in C programming for embedded systems
• Experience developing bare-metal firmware (minimal or no RTOS environments)
• Understanding of power electronics control concepts: PWM generation, current/voltage control loops, protection mechanisms
• Experience interfacing firmware with embedded peripherals (ADCs, PWM, CAN, SPI, I²C, etc.)
• Experience implementing unit testing approaches for embedded software
• Familiarity with CI/CD pipelines for firmware build, testing, and deployment
• Experience with DevOps-style workflows including version control (Git) and agile environments
• Proficiency in embedded debugging tools: JTAG/SWD debuggers, logic analysers, oscilloscopes

Desirable / Advantageous

• Experience with VHDL and FPGA-based signal processing or control
• Understanding of CPU/FPGA co-processing architectures
• Exposure to high-power or high-voltage power conversion systems
• Familiarity with control theory applied to power electronics (PI/PR controllers, feed-forward control)
• Experience using MATLAB/Simulink for modelling and control algorithm validation
• Knowledge of Python for scripting, automation, or test tooling
