Power Quality Engineer

You will support the daily operations of global data centres, ensuring the stability and efficiency of high-performance computing equipment and related assets. Through power quality monitoring, analysis, and optimization, you will reduce equipment failures and energy losses caused by harmonics, voltage fluctuations, and other disturbances, providing reliable power assurance for high-density computing facilities. You will work on-site with professional power quality analyzers, process and analyze data using tools like Python and MATLAB, identify disturbance sources, propose mitigation solutions, and participate in battery energy storage system integration assessments while staying current with international power quality standards.

Responsibilities

• Develop and implement power quality monitoring plans for data centres and critical power systems to support power availability targets (Tier III/IV class)
• Perform on-site installation, commissioning, and long-term/temporary monitoring using professional power quality analyzers, collecting parameters including voltage, frequency, harmonics, three-phase imbalance, flicker, and voltage dips/swells
• Conduct power quality data processing and statistical analysis with Python, MATLAB, or Excel, including 95th percentile evaluation, exceedance rate calculation, event waveform assessment, and trend reporting aligned with IEC 61000 series
• Identify disturbance sources including non-linear loads such as servers, UPS, and energy storage PCS inverters, and propose mitigation solutions such as active/passive filters and reactive power compensation
• Participate in battery energy storage system integration assessments, conduct pre-connection power quality reviews, on-site testing, and verification of harmonics, fluctuations, and fault ride-through metrics
• Track international power quality standards and technology trends and participate in internal technical sharing and training

Requirements

• Bachelor's degree or above in Electrical Engineering, High Voltage Technology, or related fields (Master's degree is advantageous)
• At least 5 years of experience in power quality analysis, data center power systems, or energy storage projects
• Proficient in on-site operation, data acquisition, and analysis using Fluke or equivalent power quality analyzers
• Familiar with international power quality standards (IEC 61000-4-30, IEEE 519, EN 50160, and related series)
• Proficient in data analysis tools (Python, MATLAB, advanced Excel functions, etc.) with strong statistical analysis and programming capabilities
• Experience in BESS integration, harmonic mitigation, or data center power projects
• Proficiently read technical documents and participate in international conferences
• Knowledge of data centre Tier standards and UPS/storage backup power integration experience
• Able to travel about 50% of the time
