We provide cutting-edge wavelength management and amplifier technologies, supported by deep optical, mechanical, electrical, and software integration capabilities.
These strengths enable Molex to serve the evolving needs of high-density, high-bandwidth, and flexible optical networks.
Our Team
The Senior Reliability Engineer will join an R&D team and this engineer will own reliability, qualification, and failure analysis of R&D products.
What You Will Do
* Define qualification plans (HTOL, burn-in, temperature cycling, damp heat as applicable, mechanical stress) aligned to telecom expectations and customer specifications
* Select acceleration models and parameters (Arrhenius/Peck/Coffin-Manson); compute acceleration factors and confidence bounds
* Own ongoing reliability monitoring: drift analysis, trend charts, and early-warning triggers
* Publish reliability reports, present them to internal reviews and customer audits
* Lead failure analysis (FA) for any field, qualification or production failures: containment, root cause, corrective action verification
* Perform electrical and optical characterization and degradation mapping
* Responsible for decapsulation, cross-sectioning and sample preparation
* Perform microscopy (optical/SEM) compositional analysis (EDX) and spectroscopy
* Establish rapid containment strategies (e.g., lot quarantine, risk assessment)
* Drive structured root cause analysis using formal methodologies (e.g., 8D, fault tree, fishbone, hypothesis testing)
* Maintain failure mechanism library
* Lead cross-sectional failure analysis reviews and summarize results to stakeholders
* Works closely with Laser Design/Process, Packaging/Manufacturing, Supplier Quality, and System/EDFA teams
* Coordinates with external labs for specialized metrology (SEM/EDX, advanced linewidth) and external labs for Telcordia testing
Who You Are (Basic Qualifications)
* Bachelors degree in Electrical Engineering, Physics, Materials, Mechanical or related technical degree
* At least 8 years in optoelectronic or semiconductor reliability
* Hands-on experience with Telecordia: HTOL/burn-in, environmental chambers, and statistical reliability analysis (Weibull, lognormal, exponential)
* Expertise with failure-analysis methods, especially SEM, EDX and cross-sectional analysis
* Experience with laser diode failure mechanisms (facet degradation, COD/COMD, metallization migration, solder fatigue, contamination)
* Experience with solder/metal failure modes (e.g., delamination)
* Experience designing experiments, defining sample sizes, and interpreting results with measurement uncertainty
* Experience in working in ESD labs
What Will Put You Ahead
* Masters Degree
