Senior Staff Firmware Engineer – Power Electronics Control

Your Role
In this role, you will develop and support firmware for digital power control solutions, working closely with hardware teams and customers to deliver robust, high-performance power conversion systems.

Less experience with potential candidates are also welcomed.

Key responsibilities in your new role

  • Firmware Development & Control Implementation
    • Develop, customize, and maintain embedded firmware for power electronic control applications (IBC / HVIBC preferred).
    • Implement and tune digital control loops, protections, sequencing, telemetry, and state machines for various topologies.
    • Optimize performance (efficiency, transient response, stability, fault behavior) across operating conditions.
    • Work across different programming environments and toolchains; adapt quickly to new platforms and coding ecosystems.
  • Application Bring-up, Debugging & Validation
    • Create test plans and execute validation for firmware releases, patches, and new features.
    • Debug complex system-level issues using embedded debugging techniques and lab equipment (e.g., scope, logic analyzer, power analyzer).
    • Perform root-cause analysis and drive corrective actions in firmware and/or system integration.
  • Joint Commissioning with Hardware Team
    • Support board bring-up and joint commissioning activities with hardware/power teams.
    • Align firmware parameters with hardware design constraints (sensing, gate drive, protection thresholds, component tolerances).
    • Contribute to system integration reviews and readiness for customer delivery.
  • Customer Interaction & Technical Support
    • Provide technical support for customer programs: configuration, troubleshooting, and performance optimization.
    • Communicate clearly under time pressure; drive issues to closure with structured updates and action plans.
    • Participate in customer meetings, lab sessions, and occasional travel for on-site debug/commissioning.
  • Documentation & Knowledge Sharing
    • Document firmware architecture, configuration guidelines, test results, and debug procedures.
    • Create or maintain application notes, release notes, and example/reference code as needed.
    • Share knowledge within the team to improve reuse, quality, and speed of execution.

Your Profile

Qualifications and skills to help you succeed

  • BSEE/MSEE in Electrical Engineering, Computer Engineering, or related field.
  • 4–6 years of experience in firmware development for power electronics control (digital power / embedded control).
  • Proficiency in C/C++ for embedded systems; comfortable working across multiple IDEs/toolchains and programming environments.
  • Solid understanding of power conversion fundamentals and digital control (PWM, ADC sampling, loop compensation concepts, protections).
  • Strong curiosity and problem-solving mindset: you proactively ask “why”, explore new applications, and challenge assumptions constructively.
  • Experience with IBC development (HVIBC is a plus).
  • Nice-to-have topology know-how: Totem-pole PFC, LLC, multi-phase/multiple buck, PSZVS / soft-switching concepts (or similar advanced DC/DC and AC/DC architectures).
  • Hands-on experience collaborating with hardware teams during bring-up and commissioning.
  • Customer-facing capability: dynamic communication, structured troubleshooting, and ability to work under pressure; willingness to travel occasionally.
