Job Description
Required Qualifications & Skills
Key Responsibilities
- Key Responsibilities
- Lead electrical hardware design of DX cooling units, including power distribution circuit, compressor/EEV/fan drive control, sensor sampling, protection circuit, wiring diagram, terminal definition and cabinet layout.
- Define BOM for electrical components: VFD, controller, EEV driver, current/voltage/temperature/pressure sensors, contactors, circuit breakers, relays and power supplies; conduct component selection, evaluation and single-source risk management.
- Develop electrical schematics, wiring drawings, panel layout, cable routing specification and test procedure; manage drawing release, revision and technical document control.
- Conduct EMC, electrical safety and reliability assessment; organize related verification tests (surge, ESD, conducted/radiated emission, insulation, withstand voltage, over-current/over-temperature protection).
- Support control logic integration with thermal system: compressor capacity regulation, EEV superheat control, fan speed modulation, alarm interlock, fault diagnosis and protection logic matching for DX refrigeration cycle.
- Drive DFM review for electrical design, work with manufacturing and supply chain to optimize wiring harness, panel assembly and testability; support cost optimization of electrical bill of material.
- Support prototype, pilot run and mass production ramp-up; troubleshoot electrical and control issues including communication failure, sensor drift, drive abnormal trip, protection misfire and wiring interference during NPI and volume production.
- Resolve field quality escalations related to electrical hardware, drive faults, signal noise and protection failures; conduct root cause analysis and roll out corrective & preventive actions.
- Track relevant industry standards, safety certifications and new electrical components for cooling equipment; complete benchmarking and technical pre-research for next-gen DX control platforms.
- Align with thermal, mechanical and product teams to translate product requirements into electrical design, balancing safety, reliability, performance, cost and serviceability.
- Required Qualifications & Skills
- Bachelor’s degree or above in Electrical Engineering, Automation, Control Science & Engineering, Refrigeration & HVAC or related discipline.
- 3+ years electrical hardware design experience for HVAC / refrigeration equipment; solid experience in refrigeration unit power and control circuit design.
- Proficient in E-CAD tools (EPLAN preferred); familiar with electrical drawing standards, low-voltage distribution, wiring harness design and component specification.
- Hands-on experience with EMC and electrical safety test requirements; understand common protection mechanisms for compressor, EEV and fan drive systems.
- Basic understanding of DX refrigeration cycle, superheat control and typical operating faults of direct expansion cooling systems.
- Familiar with reliability test methodology for cooling products; able to conduct electrical fault analysis and design improvement.
- Strong systematic thinking, good cross-team communication; capable of managing multiple tasks under tight NPI schedules.
- Good English reading and writing skills for technical documents and global cross-team communication.
- Preferred Qualifications
- Experience on data center mission-critical cooling products (DX CRAC, in-row cooler)
- Familiar with Modbus / BACnet communication and building management system integration
- Practical experience with variable frequency drive commissioning and EEV control tuning
- Experience supporting NPI from concept to mass production
- Knowledge of IEC, UL and other global electrical safety standards for cooling equipment
