Sr. AE (Date Center Power System-48V)

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

Key Responsibilities

• Provide technical support to hyperscale and enterprise customers in designing, validating, and optimising 48V DC/DC 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.

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

• Develop and review reference designs, test results, application notes, validation plans, and other technical documentation.

• Translate customer feedback and application requirements into actionable recommendations for internal engineering and product teams.

• Create power system specifications, test plans, laboratory reports, and technical guidance for customer applications.

• Perform system modelling and simulation using tools such as SIMPLIS, SPICE, MATLAB, or equivalent platforms.

• Evaluate system performance, including control-loop stability, efficiency, transient response, EMI, thermal behaviour, and fault protection.

• Prepare technical demonstrations, simulation results, validation reports, and presentations for customers and internal stakeholders.

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

Requirements

• M.S. or Ph.D. in Electrical Engineering, or at least five years of hands-on experience in 48V-to-xV data centre power supply design.

• Strong knowledge of power electronics, power conversion, and system-level power architectures.

• 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 cameras, Bode analysers, programmable power supplies, electronic loads, and related laboratory equipment.

• Good communication skills in English and Mandarin, with the ability to explain technical concepts and prepare clear documentation.

• Strong analytical, debugging, and problem-solving skills, with the ability to collaborate across multidisciplinary engineering teams.

• Experience with multiphase buck converters, switched-capacitor converters, LLC topologies, GaN devices, Si MOSFETs, or advanced packaging technologies is an advantage.

• Understanding of 48V data centre power distribution, including rack-level PDUs, intra-rack DC/DC interfaces, and UPS-to-DC power connections, is preferred.

• Exposure to AI server, GPU, telecom, or data centre power architectures is highly desirable.
