Firmware Engineer; Advanced Engineering

Staff/Sr. Firmware Engineer, Advanced Engineering

To support our extraordinary teams who build great products and contribute to our growth, we're looking to add a Staff/Sr. Firmware Engineer, Advanced Engineering located in TW Taipei Wugu Site.

What a typical day looks like:

• Develop and implement embedded firmware solutions for digitally controlled power conversion systems such as DC-DC converters and AC-DC converters, ensuring optimal performance.
• Design control algorithms and integrate them into system architectures, focusing on achieving high efficiency, reliability, and compliance with stringent performance requirements.
• Collaborate closely with cross-functional teams to verify that firmware meets all system needs and requirements, fostering a cooperative approach to problem-solving.
• Participate actively in design validation testing processes, engineering builds including Proto/EVT/DVT/PVT stages, and system integration testing.
• Optimize firmware through rigorous testing and analysis to ensure robust operation under diverse conditions and seamless integration with hardware components.
• Contribute to the development of bootloaders and firmware upgrade mechanisms that enable secure and reliable updates across multiple platforms.
• Implement communication protocols such as UART, SPI, I2C, and CANBUS for real-time data exchange, telemetry, and protocol compliance within complex power systems.
• Model control systems using MATLAB/Simulink or PLECS to validate designs before implementation, ensuring accuracy and effectiveness.
• Debug hardware-firmware interaction issues using tools like oscilloscopes, logic analyzers, identifying root causes efficiently.
• Support business travel requirements as needed by project timelines, demonstrating flexibility in working hours to meet critical milestones.

The experience we're looking to add to our team:

• Minimum five years of proven experience in embedded firmware development for power supply or related industries is essential.
• Power Supply FW design (C/C++) hands-on experience with MCUs, Microchip dSPIC, STM
  32, TI UCD
  3138, TI C2000.
• Comprehensive understanding of power topologies such as buck, boost, half/full-bridge circuits, LLC resonant converters, PFC modules and inverter technologies is beneficial.
• Demonstrated ability using MATLAB/Simulink or PLECS software tools for control system modelling and design enhances your suitability for this position.
• Familiarity with common communication interfaces including UART, SPI, I2C and CANBUS for real-time data exchange is important.
• Experience creating bootloaders as well as implementing secure firmware upgrade mechanisms adds value to your application.
• Ability to work independently. Develop and test power supply units by using oscillation scope (HV, current probe), electronic load, multi-meter, AC/DC source.
• Excellent analytical and problem-solving skills. Experience of power supply trouble shooting, resolve issues. Self-driven to learn new cutting-edge technology.
• Ability to effectively communicate product architectures, design proposals with internal/external worldwide stakeholders.

Here are a few of our preferred experiences:

• FPGA experience is a plus

What you'll receive for the great work you provide:

• Social Insurance (Labor Insurance, NHI, Labor Pension)
• Group Insurance (Life Insurance)
• PTO
