• Implement digital control algorithms for voltage, current, and power regulation.
• Develop firmware for PWM generation, current balancing, soft‑start and sequencing, fault protection, telemetry and monitoring, thermal management, adaptive compensation and optimization.
• Design and optimize high‑speed real‑time control loops for high‑efficiency power supplies.

DSP and Microcontroller Programming

• Program and debug DSPs, ARM microcontrollers, and digital power controllers.
• Develop low‑level firmware drivers and hardware abstraction layers.
• Optimize firmware for deterministic real‑time performance.
• Support firmware architecture scalability across multiple product platforms and work with FPGA or programmable logic interfaces when required.

Communication & System Management

• Implement digital communication protocols including PMBus, I2C, SPI, UART, CAN, and GPIO‑based control interfaces.
• Develop telemetry, configuration, diagnostics, and fault logging features.
• Support integration with system‑level power management architectures.

Control Systems & Power Electronics Collaboration

• Collaborate closely with the Lead Power Electronics Engineer on digital control loop development, compensation tuning, system stability analysis, startup and transient optimization, and protection strategies.
• Assist with hardware bring‑up, validation and debugging of new power products and support control algorithm modeling and verification.

Validation & Product Development

• Develop automated test and validation firmware tools.
• Support lab characterization including efficiency optimization, dynamic response testing, EMI troubleshooting, fault validation and thermal characterization.
• Participate in prototype debugging and production release activities and support reliability and compliance testing activities.

Required Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• 7+ years of embedded firmware development experience.
• Strong experience with digital power conversion systems.
• Strong programming experience in C, C++, and embedded real‑time systems.
• Experience programming TI C2000 DSPs, Microchip dsPIC, STM32, NXP or similar embedded controllers.
• Strong understanding of switching power supply topologies, control theory, digital compensators, PWM architectures, ADC sampling techniques, power sequencing and protection.
• Experience with lab equipment including oscilloscopes, analyzers, and power measurement systems.
• Experience debugging embedded systems in hardware environments.

Preferred Qualifications

• Experience with digitally controlled IBC architectures.
• Experience with AI server power delivery systems.
• Experience with multiphase VRM control.
• Knowledge of GaN and SiC power systems.
• Familiarity with MATLAB/Simulink or control modeling tools.
