About The Position

We are seeking a Senior MTS Reliability Engineer to own the reliability roadmap for GaN based optoelectronic products, from early concept through mass production. This role is essential for maintaining high standards of product quality and safety, supporting ongoing improvements, and upholding the organization's reputation for excellence. The position calls for strong technical skills (particularly in using physical failure analysis tools and data interpretation), analytical thinking, and effective cross-functional communication to determine root causes of failures and suggest appropriate corrective actions. Reporting to the director of process integration, you will work cross functionally with epi, fab, packaging and packaging teams to analyze failures in GaN optoelectronic devices. In this position you will be responsible for evaluating electrical, optical, thermal and microstructural properties, to uncover root cause of failure mechanisms through use of various FA and data analytical tools. You will also help centralize chip process and test results and do data mining to improve the yield and performance. Understanding device’s structure, process flow and key characteristics will be critical for this position, knowledge on laser physics will be a plus. Being able to generate organized report and present to the team will be essential for the success of reliability, yield and performance improvement.

Requirements

• Graduate degree in Applied Physics, Electrical Engineering, Materials Science, Chemistry, Mechanical Engineering, or a related physical science discipline.
• 8+ years of experience in reliability engineering, preferably with laser diodes, LEDs, photonic integrated circuits (PICs) or other III-V optoelectronic devices.
• Expertise in reliability physics, failure mechanisms, statistical modeling, and qualification testing.
• Understand fab processing and/or device physics.
• Understand characterization (LIV, spectral, thermal, optical power measurements, near/far field).
• Experience with various FA tools, including but not limited to SEM, FIB etc.
• Proficiency with data analysis tool (JMP, Python, MATLAB, Minitab, or similar)
• Document control such as FMEA, SOP, CAPA.
• Excellent communication and cross-functional leadership skills.

Nice To Haves

• knowledge on laser physics will be a plus

Responsibilities

• Perform data-driven root-cause analysis and reliability modeling to provide actionable recommendations to the epitaxy and fabrication teams for improving device reliability.
• Document process excursion related failure signature/symptoms and recommend corrective action to prevent reoccurrence of problems.
• Device reliability related failure analysis to classify the failure modes and establish failure pareto in lot qualification and various reliability test.
• Microstructure analysis to support fab process engineering work, using existing tools and external service labs.
• Conduct innovative use of new analytical tools, equipment and methodologies.
• Compare laser chip vs integrated product reliability lifetime and major failure modes, identify and fill the gap.
• Work with FA engineer for physical FA to nail down the existing weak point/failure mechanism and prevent the potential failures based on device physics and semiconductor processing knowledge.
• Work with FA engineer to develop new FA tool and metrology with service lab, as well as in-house FA tool and metrology.
