We are seeking a highly motivated and skilled Process Development Engineer to lead the development, optimization, and qualification of advanced soldering processes for high-power and high-current optoelectronic components. This role is critical to enhancing the reliability, thermal performance, and manufacturability of next-generation optoelectronic devices used in demanding applications.

Key Responsibilities:

• Process Development & Optimization:




• Design and implement improved soldering processes tailored for high-power optoelectronic components.
• Evaluate and select solder materials and surface finishes to meet thermal, electrical, and mechanical requirements.
• Develop robust process parameters for reflow, laser soldering, or other advanced joining techniques.




• Qualification & Reliability Testing:




• Define and execute qualification plans, including thermal cycling, power aging, and mechanical stress testing.
• Analyze failure modes and drive corrective actions to improve process robustness and yield.




• Cross-Functional Collaboration:




• Work closely with design, materials, and manufacturing engineering teams to ensure process compatibility with product requirements.
• Support transition of developed processes to volume production, including documentation, training, and troubleshooting.




• Data Analysis & Reporting:




• Use statistical tools (e.g., DOE, SPC) to analyze process data and drive continuous improvement.
• Prepare technical reports and present findings to internal stakeholders and external partners.

Qualifications:

• Bachelor's or Master's degree in Materials Science, Mechanical Engineering, Electrical Engineering, or related field.
• 5+ years of experience in soldering process development, preferably in optoelectronics, power electronics, or semiconductor packaging.
• Strong understanding of thermal management, metallurgy, and interconnect reliability.

• Expertise in intermetallic compound (IMC) formation and control at solder-substrate interfaces to ensure long-term reliability.

• Proficiency in advanced failure analysis methods, including SEM, EDS, X-ray, and cross-sectional analysis to investigate solder joint integrity and degradation mechanisms.

• Familiarity with solder joint reliability standards such as IPC-9701, JEDEC JESD22-A104, and MIL-STD protocols.

• Excellent problem-solving, communication, and project management skills.

Preferred Skills:

• Experience with high-current or high-power device packaging.
• Experience with high-power semiconductor lasers manufacturing and/or testing
• Background in optoelectronic component design or integration.
