Job Description Job Summary We are seeking a Senior Application Engineer with strong hands-on firmware development experience for digitally controlled low-voltage power converters, combined with practical power electronics hardware design and validation skills. This role is ideal for an engineer who enjoys working across firmware, hardware, and lab validation, and who can independently develop, debug, and validate low-voltage GaN-based power converter solutions such as DC-DC regulators, AC-DC front-end converters, and low-voltage motor drive inverters. Given the lean team structure, the candidate is expected to personally own firmware development, hardware bring-up, and lab testing, from concept through validated reference designs. Key Responsibilities Firmware Development & Digital Control Design, implement, and debug embedded firmware for digital control of low-voltage power converters. Develop and tune control algorithms such as: Digital voltage/current control loops (PID, Type II/III digital compensators) Current-mode and voltage-mode control Motor control algorithms (e.g., trapezoidal control, FOC for low-voltage BLDC/PMSM) Implement real-time firmware features including: Fault protection (OCP, OVP, OTP) Soft-start, sequencing, and system state management Telemetry, sensing, and digital communication (PMBus, UART, SPI, I²C) Optimize firmware for fast switching, low latency, and real-time performance in GaN-based systems. Power Hardware Design & Hands-On Testing Design and develop low-voltage power converter hardware using GaN FETs, including: Non-isolated and isolated DC-DC converters AC-DC auxiliary or front-end supplies Low-voltage motor drive inverters Perform hands-on hardware bring-up, debugging, and validation in the lab. Execute measurements related to: Switching behavior, efficiency, and losses Gate drive performance and dead-time optimization Thermal performance and power density EMI/EMC pre-compliance testing Actively iterate hardware designs based on lab results and firmware interaction. Hardware–Firmware Integration Validate and optimize closed-loop system performance of digitally controlled power converters. Debug complex issues spanning: Control-loop instability Noise coupling between power stage and control electronics Timing interactions between firmware and power hardware Ensure robust interaction between GaN power stages, gate drivers, sensing circuits, and control firmware. Reference Design & Evaluation Platform Development Develop evaluation boards and reference designs highlighting low-voltage GaN solutions. Deliver complete solutions including: Schematics and layouts Embedded firmware Test results and performance reports Support internal and external design enablement using these platforms. Customer & Field Support Provide deep technical support to customers designing low-voltage GaN-based power systems. Assist customers with: Firmware adaptation and tuning Hardware debugging and system optimization Participate in design reviews, customer discussions, and technical workshops. Technical Documentation & Knowledge Sharing Create high-quality application notes, design guides, and firmware documentation. Document best practices for digital control of low-voltage GaN power converters. Contribute to internal knowledge sharing and training. Qualifications Education Bachelor’s or Master’s degree in Electrical Engineering or related field Experience 5+ years of experience in: Embedded firmware development for power electronics and Hands-on power converter hardware design and validation Proven experience personally owning firmware + hardware + lab testing. Technical Skills Strong understanding of low-voltage power electronics, including: DC-DC topologies (buck, boost, buck-boost, resonant) Motor drive inverters for low-voltage systems Solid grasp of digital control theory applied to power converters. Embedded C/C++ programming for real-time systems. Experience with microcontrollers or DSPs commonly used in digital power and motor control. Proficient with lab equipment: oscilloscopes, power analyzers, current probes, signal generators. Schematic capture and PCB design experience (Altium or equivalent). Additional Hardware Design Capability Hands-on experience creating power electronics schematics and reviewing component selection for low-voltage GaN-based converters. Practical experience with PCB design and layout for high‑speed, low‑voltage GaN power stages, including: Gate drive and power loop optimization Current sensing and feedback routing Noise mitigation and grounding best practices Comfortable performing PCB bring-up, rework, and debug, including probing fast-switching GaN nodes and resolving layout-related issues. Preferred Qualifications Direct experience with low-voltage GaN-based power converters. Experience with high-frequency switching optimization and layout-sensitive designs. Familiarity with simulation tools (PLECS, MATLAB/Simulink) for control and power-stage modeling. Experience supporting customers or field applications. Soft Skills Comfortable working in a small, hands-on engineering team. Strong debugging mindset and system-level thinking. Clear communication skills for customer-facing and internal collaboration.
