TM-Mechanical Engineer(Global)-Shenzhen

Job description

Key Responsibilities

Lead structural and mechanical design of DX cooling units, including frame, cabinet, air duct, component mounting, piping layout, vibration isolation, panel and enclosure design; ensure alignment with thermal performance, airflow, piping arrangement and serviceability requirements.

Conduct structural calculation and simulation

static strength, modal/vibration analysis, shock & transportation simulation, pressure vessel check for refrigerant piping assembly; define structural acceptance criteria. Create 3D models, 2D manufacturing drawings, BOM, assembly instructions and mechanical technical specifications; manage drawing release, revision and technical document control. Drive DFM/DFA review for DX products, collaborate with manufacturing and supply chain to optimize structure design for machining, sheet metal fabrication, welding, piping assembly and field installation; control structural BOM cost.

Organize mechanical validation tests

transportation vibration, shock, IP rating, corrosion, noise, tightness test, structural durability; analyze test failure, identify root cause and implement design corrective actions. Support prototype, pilot run and mass production ramp-up; resolve on-site structural, assembly, interference, leakage and vibration issues during NPI and volume production. Support field quality cases and customer escalations related to mechanical/structural failure, piping crack, vibration, cabinet deformation and air leakage; provide technical root cause analysis and improvement plans.

Benchmark competitor mechanical design, track new structural materials, sheet metal processes and modular design technologies; propose structural optimization and cost-down solutions for new DX platforms. Coordinate with thermal, controls, product and QA teams to translate product requirements into feasible structural design, balance performance, reliability, cost and lead time.

Required Qualifications & Skills

Bachelor’s degree or above in Mechanical Engineering, Mechatronics, Refrigeration & HVAC or related discipline. 3+ years mechanical/structural design experience on refrigeration or HVAC equipment; solid experience in sheet metal structure, refrigerant piping layout, vibration control and cabinet design. Proficient in 3D CAD tools (SolidWorks / Creo / Inventor), familiar with mechanical drawing standards, GD&T, sheet metal and welding process.

Hands-on experience with structural simulation tools (Ansys / Abaqus / Simcenter preferred); capable of vibration, modal and strength assessment. Familiar with reliability test methods for cooling equipment, packaging & transportation test, IP protection, material selection and anti-corrosion design. Knowledge of DX CRAC / direct expansion cooling unit mechanical layout is preferred; understand basic refrigeration piping and assembly constraints.

Systematic troubleshooting mindset, good cross-functional communication; able to handle multiple tasks under tight NPI schedules. Good English reading and writing skills for technical documents and global team communication.

Preferred Qualifications

Experience in data center mission-critical cooling products (DX CRAC, in-row cooler) Familiar with refrigerant piping stress analysis and vibration suppression for compressor systems Experience leading mechanical design from concept to mass NPI launch Experience with modular structure design and service-friendly design for field maintenance
