Job Details

The Reliability Engineer (Laser Diode Failure Analysis Engineer) will lead reliability improvement and failure analysis

efforts for proprietary next-generation GaN-based UV/VIS laser technology across multiple markets, such as

Industrial, Electronics, Scientific, Biotech, General lighting, and Automotive. Candidates must have experience in

Failure Analysis of Laser Diodes and provide solutions to relevant, complex technical problems, ideally within

Commercial as well as Defense and Government-funded industries. Candidates must demonstrate expert analytical,

problem-solving, laser diode multi-cell reliability modeling (FIT models, HAST, and HALT testing) and practical

laboratory-based experience in multiple optoelectronic technologies, including FP, DFB, DBR, or VCSEL

semiconductor laser diodes.

Objective:

Oversee all aspects of the reliability data analysis, testing, modeling, and reporting of next-generation GaN Diode Lasers

that leverage the advantages of proprietary Remote Plasma CVD (RPCVD) deposition technology. This role

will contribute reliability and FA concepts during new product development, qualification, and ongoing production.

Principal areas/functions:

75% Reliability Improvement and Failure Analysis:

Establish burn-in, HAST, HALT, and muti-cell reliability protocols supporting product development, product

qualification, and production screening.

Oversee failure analysis (FA) process as needed to determine root cause using internal resources or external

vendors. Provide feedback for device design evolution.

Analyze the laser device performance throughout development and reliability testing. Apply device physics and

laser design understanding to correlate any performance drifts to design inputs.

Monitor GaN Laser Diode component level qualification stress tests to meet customer requirements and ensure

high-quality operation in the field. Stress testing includes accelerated lifetime tests, environmental tests,

mechanical tests, ESD, etc.

Collaborate with and learn from device design engineers and technical program managers (PMs) on new

products from the initial concept through release to manufacturing.

Develop, execute, and improve qualification plans, internal infrastructure as well as external contract

manufacturers (CMs).

Collaborate with test engineers and technicians to execute functional testing for each product. Tests include

laser current-power-voltage, spectra/junction temperature measurements, near and far field measurements,

etc.

Provide updates on the qualification testing in the form of email updates, customer-facing presentations, internal

NPI reviews, and documented qualification reports.

Define key technical objectives and manage projects through the various development phases (feasibility, alpha

[design and development], beta [reliability and qualification]) and into production to meet program milestones

and product reliability requirements.

Collaborate with internal epitaxial design & growth team to determine optimal epitaxial wafer design and

growth parameters (specifically the calculation, tracking, and improvement of laser gain and loss

characteristics).

Collaborate with testing and reliability groups and participate in the design and setup of new test systems

needed to measure laser diode performance

25% Technical Program Interaction:

Maintain knowledge of state-of-the-art principles for advancing the performance of laser diodes.

Monitor Laser Diode performance in development and production

Establish, monitor, analyze, and report key performance metrics to project teams and management.

Participate in the development of Patent Applications.

Publish & Present results at Industry Events & Trade shows.

Participate in program reporting, proposal writing, and program management for commercial and government

programs.

Background/Skills:

Masters's degree in Electrical Engineering, Physics, or Materials Science with 8+ years of experience or a Ph.D.

+3 years of experience in Laser/Laser Diode environment

Experience in Gallium Nitride materials systems (design/modeling, epitaxy, fabrication, or testing) is highly

desirable.

Development and execution of a Failure Analysis strategy

Demonstrated leadership ability and the ability to direct and influence the organization across multiple functional

departments is essential. Strong team player.

Hands-on testing specifically or laser diodes including light-current-voltage (LIV), spectra, near field and far field

beam parameters under CW is a plus

Hands-on testing of reliability stress such as accelerated temperature, high humidity, temperature and power

cycling, ESD is a plus

Deep statistical analysis of large datasets

Experience with software data analysis tools (JMP, Minitab, Excel or similar) and data processing software

(Python, Matlab or similar)

Knowledge of semiconductor device physics and/or reliability engineering is a plus

Strong organizational and decision-making skills.

Good communication skills (both oral and written) are required
