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.
