Sr. AE (800V)

About the Company Our client develops advanced semiconductor and power management solutions for high-performance computing and infrastructure applications. The team works with customers and cross-functional engineering groups to support next-generation power conversion and distribution architectures for data centres and server platforms.

Key Responsibilities

• Provide technical support to hyperscale and enterprise customers in designing, validating, and optimising 800V high-voltage DC (HVDC) power solutions for server, storage, networking, and data centre applications.

• Support system bring-up, hardware debugging, performance characterisation, validation, and customer qualification throughout the design cycle.

• Develop system architectures for high-power-density DC-DC converters, intermediate bus converters (IBCs), and HVDC power delivery solutions.

• Define power system specifications, requirements, validation plans, and reference designs; prepare laboratory reports, application notes, and technical documentation.

• Collaborate with IC design, magnetics, packaging, thermal management, and firmware teams to deliver integrated system-level solutions.

• Perform modelling and simulation using tools such as SIMPLIS, SPICE, MATLAB, PLECS, or equivalent platforms to evaluate system behaviour under different operating conditions.

• Analyse control-loop stability, conversion efficiency, transient response, EMI, thermal performance, and fault protection.

• Develop technical demonstrations, validation results, and presentations for customers and internal engineering teams.

• Support sales activities through technical training, customer discussions, solution positioning, and design-in engagement at key accounts.

• Prepare technical documentation in English and Mandarin and present technical findings to global stakeholders when required.

Requirements

• M.S. or Ph.D. in Electrical Engineering, or at least five years of hands-on experience in data centre power supply design.

• Strong knowledge of power electronics, power conversion architectures, and high-power-density system design.

• Solid understanding of magnetics and converter topologies, including resonant converters (LLC/DAB/CLLC), multiphase buck converters, and switched-capacitor converters.

• Familiarity with power semiconductor devices, including GaN, and their application in high-efficiency power conversion.

• Experience with system modelling and simulation tools such as LTspice, SIMPLIS, or PLECS.

• Familiarity with hardware design tools such as Altium Designer or Cadence Allegro.

• Hands-on experience with power analysers, high-bandwidth oscilloscopes, thermal imaging cameras, Bode analysers, programmable power supplies, and electronic loads.

• Understanding of high-voltage power distribution architectures, including 48V, 400V, and 800V DC systems.

• Strong written and verbal communication skills in English and Mandarin, with the ability to explain complex technical concepts clearly.

• Experience working with hyperscale customers on system bring-up, design debugging, and technical issue resolution is an advantage.

• Publications or patents related to GaN-based converter design or advanced packaging technologies are a plus.
