Senior Mechanical Design Lead for Precision Machines (0-1)

HAN'S CNC; Hong Kong; On-site; HKD 900,000 - 1,300,000; Full time

Job summary

Han's CNC, a global leader in PCB specialty equipment, is seeking a Senior Mechanical Design Lead in Hong Kong. The role drives the architecture of large precision machines, including motion stages and clamps, with a focus on accuracy and robust design from concept through validation.

You will own tolerance chains, select materials, and guide prototype assembly and tuning, coordinating with China-based teams. Mandarin Chinese is required for effective collaboration.

Qualifications

• Master's degree or above in Mechanical Engineering, Precision Instruments, Mechanics, Mechatronics, or related fields.
• 8+ years of mechanical design experience in high-precision equipment/instruments; led at least one high-precision machine from concept to validation.
• Deep understanding of large precision machine design: materials, structures, tolerance chains, error budgeting; familiar with sourcing for high-precision motion systems.
• Hands-on with linear motors, air-bearing/rolling guides, ball screws, flexure hinges, encoders/laser interferometers; capable of selection, calculation, tuning.
• Knowledge of precision machining processes and materials (metals, ceramics, low-expansion alloys).
• Experience assembling large precision equipment; write SOPs, establish alignment/datum systems, coordinate on-site integration.
• Preferred: experience in advanced packaging or semiconductor front-end equipment; precision of 1 μm or better.
• Mandarin Chinese proficiency is required.

Responsibilities

• Lead whole-machine architecture definition and precision budget allocation (layout, metrology, load-bearing frames, motion axes).
• Drive systematic accuracy improvements; build test/traceability schemes and roadmaps.
• Own design of key modules — motion stages, transmission, guidance, workpiece clamping; select materials and manage thermal design.
• Oversee prototype assembly, tuning, and write precision verification matrices and test plans.
• Lead root-cause analysis and closure of structural issues; guide on-site integration and alignment.
