Job Summary:
Coherent is currently hiring a Senior Manufacturing Engineer to work at our manufacturing site located in Singapore. We are looking for a hands-on candidate for our industry-leading laser technology products. The Manufacturing Engineer will be responsible for developing, optimizing, and maintaining the manufacturing processes used in the production of laser systems and optical assemblies. This role ensures high-yield, cost-effective, and reliable production through continuous process improvement, equipment qualification, and close collaboration with design, quality, and supply chain teams. The engineer will be a key technical link between R&D and production, focusing on scalability, manufacturability, and operational excellence.
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.
