Mechanical Design Lead

HAN'S CNC; Hong Kong; Sur place; HKD 900 000 - 1 300 000; Plein temps

Résumé du poste

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.

Responsabilités

• 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.

About Han's CNC

Han's CNC (SZSE: 301200; HKEX: 3200) is the world's largest PCB specialty equipment supplier, serving 80% of the Prismark Global Top 100 manufacturers and holding ~50% global share in AI-server PCB drilling. Dual-listed in Shenzhen and Hong Kong, we're expanding fast overseas — and this role sits at the core of our precision engineering push.

What you'll do:

• Lead whole-machine architecture definition and precision budget allocation (layout, metrology & load-bearing frames, motion axis configuration, vibration isolation).
• Drive systematic accuracy improvement of existing platforms: build precision test/traceability schemes, identify root causes, and deliver improvement roadmaps.
• Own the design of key modules — motion stages, transmission/guidance, workpiece clamping — including material selection, thermal management, tolerance chain design, and simulation.
• Guide prototype assembly and tuning; define precision verification matrices and test plans; lead root-cause analysis and closure of structural issues.

What we're looking for:

• Master's or above in Mechanical Engineering, Precision Instruments, Mechanics, Mechatronics, or related fields.
• 8+ years of mechanical design experience in high-precision equipment/instruments; must have led at least one high-precision machine or core motion platform from 0 to 1 (concept → machining → assembly → tuning → validation → iteration), with clear ownership of design scope and validation methods.
• Deep understanding of large precision machine design: material selection, structural design, tolerance chains, and error budgeting; familiar with component sourcing and supply chains for high-precision motion systems.
• Hands-on familiarity with linear motors, air-bearing/rolling guides, ball screws, flexure hinges, encoders/laser interferometers — selection, calculation, and tuning.
• Knowledge of precision machining processes and material properties (metals, ceramics, low-expansion alloys).
• Experience in assembly integration of large precision equipment; able to write assembly SOPs, establish alignment/datum systems, and coordinate on-site integration.
• Preferred: experience in advanced packaging or semiconductor front-end equipment; theoretical precision of 1 μm or better.
• Mandarin Chinese proficiency is required — this role works closely with China-based engineering teams.
