About Cooler Master
For over three decades, Cooler Master has been a trusted partner to tier-1 global technology leaders, delivering pioneering thermal and manufacturing solutions. As AI computing workloads and next-generation data centers continue to push the boundaries of power density, Cooler Master is at the forefront of the industry—manufacturing critical high-density liquid cooling, CDU (Coolant Distribution Units), and advanced thermal infrastructure that power the global AI boom.
Driven by Innovation, Agility, and Professionalism, our culture is built on the "Cooler Master Spirit"—a collaborative environment rooted in structured discipline, teamwork, and accountability. We offer a fast-paced, technology-driven workplace where high-energy professionals can build the physical infrastructure of the future. If you thrive in a forward-moving atmosphere and want to grow at the speed of the AI revolution, this is the place to define your career.
Position Overview
We are seeking a highly skilled Electrical Engineer specialized in power conversion to lead the end-to-end development of high-efficiency power systems. This role focuses on the architecture, detailed design, rigorous analysis, and hardware validation of DC-DC converters, AC-DC power supplies, and inverter systems. You will be responsible for ensuring that all designs meet stringent performance metrics, thermal constraints, and global EMI/Safety regulatory standards.
Key Responsibilities
Hardware Design & Prototyping:
Design and develop power conversion topologies (e.g., Buck, Boost, Flyback, LLC Resonant, Phase-Shifted Full Bridge).
Select critical components including power MOSFETs/IGBTs, Wide Bandgap (GaN/SiC) devices, and magnetic elements.
Create detailed schematics and supervise high-power PCB layouts, ensuring optimal grounding and parasitic minimization.
Analysis & Simulation:
Perform circuit simulations using tools like SPICE, PLECS, or MATLAB/Simulink to predict steady-state and transient behavior.
Conduct Worst-Case Analysis (WCA), Stress Analysis (Component Derating), and Stability Analysis (Bode plots/Control loop modeling).
Execute thermal modeling to ensure reliability across the full operating temperature range.
Compliance & Magnetics:
Design and specify custom magnetic components (inductors, transformers) for high-frequency switching.
Implement EMI mitigation techniques (filter design, shielding, and layout optimization) to meet FCC/CISPR requirements.
Ensure hardware adheres to international safety standards (e.g., UL 62368-1, IEC 60601, or ISO 26262).
Validation & Testing:
Perform hands-on "bring-up" and debugging of complex PCBAs.
Develop and execute comprehensive test plans for efficiency, thermal performance, and protection features (OVP, OCP, OTP).
Utilize advanced lab equipment, including high-bandwidth oscilloscopes, power analyzers, and electronic loads.
Qualifications
Education: Bachelor’s or Master’s degree in Electrical Engineering (Power Electronics concentration preferred).
Experience: 3+ years of professional experience in switch-mode power supply (SMPS) design.
Technical Skills:
Deep understanding of control theory and analog circuit design.
Proven track record of taking a power product through EMI/EMC (conducted and radiated emissions) and Safety certification.
Proficiency in Altium Designer, Cadence Allegro, or similar EDA tools.
Soft Skills: Strong analytical mindset, attention to detail, and the ability to collaborate with mechanical and firmware teams.
Preferred Skills
Experience with Wide Bandgap (SiC/GaN) semiconductor integration.
Knowledge of digital control implementation using microcontrollers or DSPs.
Familiarity with functional safety requirements (ASIL levels).
Note on Compliance: A successful candidate must demonstrate the ability to balance high power density with the physical requirements of creepage, clearance, and thermal management.
Benefits:
Starting with 15 paid vacation days in the first year
11 paid corporate holidays + 5 bonus holidays
5 paid sick leave days per year
Comprehensive Medical, Dental, and Vision insurance plans
FSA & HSA plans available
Advanced health plan options with employer-subsidized out-of-pocket premiums
Company-sponsored Life Insurance
401(k) retirement plan with company match
Position Details:
Employment type: Full Time
Location: On-site at Fremont, CA
For Pay Transparency-Compensation Description (Annually)
The base salary range for this position in the selected city is $80,000 - $95,000 annually.
Compensation may vary outside of this range depending on a number of factors, including a candidate’s qualifications, skills, competencies and experience, and location.
