Firmware Engineer

You'll report to the Firmware Team Lead and play a key part in developing next-generation switch-mode power supplies. The work covers firmware architecture, development, verification and prototyping, through to supporting manufacturing at product launch. It's a hands-on senior role where you'll also give technical direction and mentor junior engineers.

Key Responsibilities

• Contribute to product definition, specifications and requirements analysis with cross-functional stakeholders
• Shape firmware architecture and development strategy, especially for wired and wireless communications
• Design, code, integrate, test and enhance embedded and PC software for power conversion systems in a regulated development environment
• Design new products to spec and on schedule, and improve existing designs for performance and cost
• Run system integration, validation and interoperability testing, including automated test programs
• Evaluate existing and emerging technologies for reliable operation across diverse installed environments
• Take part in software qualification activities, including SFMEA and code reviews
• Support prototypes, BETA production runs and factory teams on design-related issues
• Work with local and remote hardware and software teams on integration
• Coach junior firmware engineers and give technical direction to the team

What You'll Bring

• Bachelor's or Master's degree in Computer Science, Computer Engineering, Electrical Engineering or a related field
• 5–7 years of embedded firmware development experience
• Strong embedded C skills on Microchip, TI and/or ST microcontrollers and DSPs
• Experience developing communication stack drivers and protocols such as I2C, SPI, RS-485, PMBus, Modbus and Ethernet
• Experience with embedded control or signal-processing (DSP) algorithms
• Comfortable debugging in embedded environments, including reproducing intermittent failures
• Confident with lab equipment (oscilloscopes, multimeters, power supplies) and with reading schematics and datasheets
• Familiar with version control (e.g. SVN) and release methodologies
• Disciplined and detail-oriented, writing robust, readable code
• Strong analytical and problem-solving skills, and comfortable working with remote teams

Nice to Have

• Digital control or firmware for power electronics (PWM, ADC, digital filters)
• Understanding of power supply topologies and analog/digital circuitry
• IoT, TCP/IP, WebSocket, LwIP or FreeRTOS experience
• Software development in C# and GUI tools
• Familiarity with MISRA, IEC 62304 or other coding standards
