• Sealing Technologies: Develop and implement advanced sealing technologies (such as hermetic and adhesive bonding) to ensure environmental protection and prevent degradation over time.
• Reliability and Testing: Oversee the testing and validation of packaging solutions, performing rigorous reliability testing and failure analysis (e.g., accelerated life tests, thermal cycling, and optical performance evaluation).
• Cross-functional Collaboration: Work closely with cross-disciplinary teams (mechanical engineering, electrical engineering, and manufacturing) to integrate packaging solutions with the overall system design.
• Process Improvement: Identify and drive improvements in packaging technologies, materials, and processes to reduce cost, improve performance, and increase yield.
• Vendor Management: Support the purchasing department with suppliers to source packaging materials, components, and tools, ensuring high-quality standards and adherence to project timelines.
• Documentation and Reporting: Prepare comprehensive technical documentation, including design specifications, test results, and reliability reports. Present design progress, test results, and solutions to internal and external stakeholders.
• Mentorship: Provide technical leadership and mentorship to junior engineers and technicians, fostering a culture of continuous learning and innovation within the packaging team.
• Project Management: Manage multiple packaging projects simultaneously, ensuring on-time delivery and maintaining high levels of product quality throughout the process.

Qualifications:

• Bachelor\’s or Master\’s degree in Electrical Engineering, Optics, Materials Science, Physics, or a related field.
• Minimum of 5-7 years of experience in laser diode packaging, optoelectronics, or semiconductor packaging, with a strong focus on microoptics, submounts, and sealing technologies.
• Proven experience in designing and implementing laser diode packaging solutions involving optical integration, submounts, and thermal management.
• Expertise in the application of sealing technologies (hermetic sealing, adhesive bonding, etc.) for optoelectronic components.
• Strong understanding of optical alignment, coupling, and light extraction methods for high-performance laser diodes.
• In-depth knowledge of materials used in laser diode packaging, including metals, ceramics, and polymers.
• Experience with reliability testing of optoelectronic devices and failure analysis techniques.
• Strong project management skills with the ability to lead and coordinate teams across multiple functions.
• Exceptional communication skills, with the ability to present complex technical information to both technical and non-technical stakeholders.
• Ability to work in a fast-paced environment and manage competing priorities.

Preferred Qualifications:

• Ph.D. in a relevant field (e.g., Optics, Materials Science).
• Experience with high-volume manufacturing processes and scaling packaging solutions for mass production.
• Hands-on experience with simulation tools (e.g., COMSOL, Ansys) for optical, thermal, and mechanical analysis.
• Familiarity with ISO/IEC standards and best practices in packaging and optoelectronics.
• Previous experience in product ownership or as a technical lead for optoelectronic or photonic devices.

Why Join Us?

• Competitive salary and comprehensive benefits package.
• Opportunity to work on cutting-edge laser diode technologies with a focus on microoptics and advanced packaging solutions.
• Be part of a dynamic team where your technical contributions will drive product innovation and performance.
• Career growth opportunities in a fast-paced and evolving industry.
• Collaborative, innovative work environment with exposure to cross-disciplinary engineering challenges.
