[ref. g39791318] Senior / Principal Senior Engineer (Power System Design) - Yishun

Role Overview:

We are seeking a highly skilled Senior Engineer to lead the design and validation of power distribution systems for Tier III data centers and AI server environments. This role involves working with high-power DC systems, ensuring compliance with global standards, and collaborating across multidisciplinary teams to deliver robust and reliable power infrastructure.

Key Responsibilities:

• Design and develop DC power distribution systems, including circuit breakers, switch boxes, and protective devices tailored for data center applications.
• Perform hardware testing of power supplies and converters used in AI server racks, ensuring optimal performance under high-load conditions.
• Conduct high-power testing using AC/DC sources ranging from kilowatts to megawatts, simulating real-world data center loads.
• Execute reliability and immunity tests such as:

1. Power Surge
2. Voltage dips and fluctuations
3. EMC, EMI, and Hi-Pot

• Carry out design verification and performance evaluations, including:

1. Startup behavior
2. Transient response
3. Step response and dynamic analysis
4. Gain and phase measurements

• Generate detailed technical reports summarizing test results, design evaluations, and compliance findings.
• Maintain and update test protocols in alignment with the latest IEC, EN, UL, and IPC standards.
• Ensure designs meet TIA-942 and Tier III data center requirements.
• Collaborate with electrical, mechanical, and firmware engineers to integrate power systems into broader infrastructure solutions.

Qualifications & Requirements:

• Degree or Diploma in Electrical & Electronic Engineering.
• Minimum 5 years of experience in power distribution design, preferably in data center or industrial environments.
• Strong knowledge of TIA-942 standards and Tier III data center architecture.
• Familiarity with IEC/EN/IPC compliance and testing procedures.
• Hands-on experience with power protection systems (circuit breakers, relays, ground fault protection).
• Proficient in using high-power test equipment and diagnostic tools.
• Excellent communication skills with the ability to work cross-functionally in a fast-paced engineering environment.

Preferred Skills:

• Experience with AI server infrastructure and modular data center design.
• Understanding of thermal management and power redundancy strategies.
• Knowledge of energy efficiency standards and sustainability practices in data centers.
