Job summary

Lumilens in Singapore is seeking a Staff Mechanical Automation Engineer to lead mechanical design, analysis, and qualification of automation systems for high-volume optical and electro-mechanical assemblies. You will partner cross-functionally with process, test, quality, and product engineering teams to translate requirements into manufacturable, testable, and scalable production solutions.

This is a senior technical role with significant influence on tooling strategy and manufacturing

Qualifications

Hands-on DFM experience with optical or opto-mechanical assemblies, including tolerancing for optical alignment and contamination control.
Proficiency in worst-case and/or statistical tolerance analysis for automation.
Practical expertise applying FEA to structural, vibration, and fatigue analysis of fixtures and mechanical assemblies.
Ability to model thermal behavior during assembly and test, and to design fixtures that manage heat and drift.
Experience designing, building, and qualifying jigs and fixtures for automated manufacturing from concept through production.
Experience designing mechanical structures and fixturing compatible with ICT requirements.
Bachelor’s or Master’s degree in Mechanical Engineering/Mechatronics with 8+ years in manufacturing/automation.
Proficiency with 3D CAD tools and GD&T.

Responsibilities

Lead mechanical design and DFM reviews for optical and opto-mechanical assemblies, optimized for high-yield, high-volume manufacturing.
Own tolerance analysis (worst-case and Monte Carlo) for automated assembly and test processes.
Perform FEA to validate stiffness and durability of fixtures and automation hardware.
Develop thermal models to predict drift and heat-related failure modes.
Design, prototype, and qualify automated and semi-automated jigs and fixtures from concept through production.
Design mechanical structures and fixturing for ICT compatibility, including probe access and alignment.
Drive root-cause investigations for mechanical yield or reliability issues and implement corrective actions.
Collaborate with Process, Automation, Test, and Quality Engineering to define equipment requirements for NPI and sustaining programs.
Create and maintain design docs, drawings, FMEAs, and validation reports for design reviews and manufacturing readiness.
Mentor junior and mid-level engineers across automation and tooling initiatives.
