The Senior Manufacturing Process Engineer will lead the development and scaling of precision opto-mechanical assembly processes, collaborating with various teams to ensure high-quality production and continuous process improvements.
AutomotiveAutonomous VehiclesInformation TechnologySemiconductorSensor
Responsibilities
Own process definition and control for automated microlens alignment and bonding. Program motion sequences, optimize camera and vision-based routines, and tune process parameters (alignment offsets, bonding dwell, UV cure profiles, placement forces) to achieve sub-micron accuracy and high yield
Define and maintain process parameters for high-precision die-attach and placement equipment. Drive correlation between pick-and-place accuracy, epoxy flow, and bond-line thickness for consistent optical coupling
Establish and control parameters for automated dispense systems. Develop dispense recipes controlling needle diameter, pressure, time, temperature, and material conditioning. Characterize cure profiles and shrinkage impacts on optical alignment stability
Design and execute structured DOEs to characterize process sensitivity and optimize yield. Use statistical methods to quantify variability and identify dominant factors affecting alignment accuracy, void formation, or optical loss
Define measurement methods and run GR&R studies on critical parameters (e.g., placement accuracy, epoxy volume, bond-line thickness). Ensure metrology tools and data systems at the CM are calibrated and controlled
Lead the implementation of robotics, automation, and material handling solutions by partnering with automation suppliers and contract manufacturers to enable scalable, high-throughput production. Drive failure analysis (FA) and corrective actions (CA) on process-related issues, and continuously improve yield, throughput, and takt time. Partner with the contract manufacturer to qualify processes, train operators, and own line readiness for precision optical assembly builds
Qualification
Required
BS or MS in Mechanical, Manufacturing, Photonics, or Electrical Engineering (or equivalent experience)

Understanding of cleanroom protocols and ESD control best practices
Familiarity with ISO 9001 process control or automotive-style production quality systems
Understanding of photonic packaging materials (epoxies, UV adhesives, underfills) and their environmental stability
Background in precision metrology systems (e.g., digital microscopes, interferometers, or confocal profilers)
Benefits
Competitive salary and meaningful equity package
