As aMechanical

Engineer, you will take ownership of subsystem design, modeling, validation, and engineering documentation for Delta’s solution portfolio.

You will collaborate with architects, product managers, R&D centers in Taiwan, and global manufacturing sites to translate customer requirements into engineered, manufacturable, and cost-optimized solutions.

Engineering & Architecture

• Develop power and cooling subsystem designs for containerized data centers, AI pods, and modular AI-factory cell architectures.

• Perform calculations and modeling for:

• Power systems (UPS, BESS, LV distribution, HVDC)

• Thermal systems (liquid cooling loops, CDUs, CRAHs/CRACs, heat transfer)

• Generate andmaintainengineering drawings, schematics, and BOMs.

• Conduct feasibility studies, tradeoff analysis, andcomponentselection.

Technical Execution

• Support prototype development, engineering lab testing, instrumentation setup, and validation results.

• Participate in DFMEA, reliability assessments, and design review cycles.

• Ensure compliance with UL, IEC, NFPA, NEC, ASHRAE, BICSI, TIA-942, and applicable Delta engineering standards.

Cross-Functional Collaboration

• Work with product management, manufacturing, industrialization, and supply chain to ensure smooth NPI transitions.

• Provide technical inputs for customer engagements, RFP/RFI responses, and solution packs.

Innovation & Continuous Improvement

• Identify improvements in power/thermal architecture, manufacturability, performance, or cost.

• Contribute to Delta’s roadmap for AI-factory power and cooling technologies.

• Master’s degree (MS) in Electrical Engineering, Mechanical Engineering, Energy Systems, or similar field.

• 3+ years of engineering experience (MS requirement meets Senior Engineer criteria)

• Experience in at least one of the following:

• Power distribution systems (UPS, PDU, switch gear, LV/HVDC)

• Data center cooling (liquid cooling, CDUs, chillers, CRAH/CRAC)

• Rack-level…
