Job description

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

• Interface with Design Engineering for Design for Manufacturability (DFM) reviews and prototype builds.
• Collaborate with Supply Chain and Vendors to ensure component quality and manufacturability.
• Support NPI (New Product Introduction) transitions from R&D to production.

6. 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.

Education & Experience

• A bachelor’s or master’s degree in engineering or its equivalents with at least 3‑5 years of relevant work experience in Photonics or a related manufacturing field.
• 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.
• Excellent interpersonal skills with good verbal and written communication skills.
• Self‑directed and able to work independently with little or no direct supervision.

Working Conditions
