Manufacturing Engineer

Primary Duties & Responsibilities

1. Process Development and Optimization

Develop, document, and implement manufacturing processes for laser modules, optical assemblies, and related sub-systems.

Define critical process parameters for optical alignment, bonding, soldering, and laser cavity assembly.

Conduct DOE (Design of Experiments) and SPC (Statistical Process Control) to optimize yield and minimize process variability.

Translate R&D prototypes into robust, repeatable production processes.

2. Production Support

• Provide hands-on technical support to production teams for troubleshooting yield issues, process deviations, and equipment downtime.
• Implement root cause analysis and corrective actions for production failures (using tools like DMAIC, FMEA, Ishikawa).
• Support daily manufacturing operations to meet production schedules and performance targets (throughput, yield, quality)

3. Equipment and Tooling Management

• Specify, qualify, and maintain production equipment such as optical benches, alignment stations, bonding systems, and test setups.
• Design and procure custom fixtures, jigs, and alignment tools to improve precision and throughput.
• Ensure calibration and preventive maintenance of manufacturing and metrology tools

4. Quality and Continuous Improvement

• Work with Quality and Reliability teams to ensure process compliance to ISO 9001 / ISO 13485 standards.
• Develop and update process documentation: work instructions
• Drive Lean and Six Sigma initiatives for process improvement, waste reduction, and cost optimization.

5. Cross-Functional Collaboration

• Collaborate with core team members for meeting product KPI like on-time-delivery, cost & quality improvements
• Collaborate with Supply Chain and Vendors to ensure component quality and manufacturability

6. Product transfer and NPI

• Support new product transfer activities including training at BU/R&D site (Typically from US or German BU)
• Support NPI (New Product Introduction) transitions from R&D to production.
• Collaborate with R&D engineers for product development and improvements.
• Interface with Design Engineering for Design for Manufacturability (DFM) reviews and prototype builds

7. Data Analysis and Reporting

• Collect and analyze process data to identify trends and improvement opportunities.
• Implement real-time data collection and traceability systems (MES, SPC dashboards).
• Present yield, performance, and process capability metrics to management

Qualification & Experience:

Bachelor's degree in Optical Engineering, Photonics, Electrical & Electronic Engineering, Applied Physics, or related discipline.

5-10 years of relevant work experience related manufacturing field. Experience in Photonics, laser alignment, optics assembly/systems, precision electronics manufacturing is preferred but not a must

• Possess technical expertise pertaining to Manufacturing, Assembly & Test Processes for mechanical assemblies, PCBA and optical components.
• Strong problem-solving skills and excellent knowledge in Six Sigma DMAIC approach, Lean principles, DOE, SPC, FMEA, GR&R and other quality improvement tools. Certified Six Sigma Green or Black Belt will be an advantage.
• Knowledge of Lab View, Python, Matlab, Zemax, Solidworks is valuable plus
• Excellent interpersonal skills with good verbal and written communication skills.
• Self-directed and able to work independently with little or no direct supervision

Leadership capabilities to lead projects or team of technicians
