Sr. Failure Analysis Engineer

Amazon Lab126 is an inventive research and development company that designs and engineers high-profile consumer electronics. Lab126 began in 2004 as a subsidiary of Inc. originally creating the best-selling Kindle family of products. Since then we have produced groundbreaking devices like Fire tablets Fire TV and Amazon Echo. What will you help us create Work hard. Have fun. Make history.
The China Product Integrity (CPI) Failure Analysis lab safeguards the material and chemical integrity of Amazon devices from polymers adhesives and coatings to metals glass and surface treatments. We investigate how materials interact with real-world environments (sweat sebum cosmetics humidity temperature and mechanical stress) and turn those findings into design and manufacturing improvements.


Key job responsibilities
As a Senior Failure Analysis Engineer in the CPI lab you will be the domain expert for chemistry- and materials-related failure analysis with a strong ability to identify root causes develop effective solutions and communicate findings to cross-functional teams. Your contributions will directly impact product quality reliability and timelines. Your responsibilities will include:
Conducting rapid root cause analysis for materials- and chemistry-related issues arising from testing manufacturing and field operations including environmental stress cracking (ESC) corrosion adhesive/coating delamination contamination discoloration and chemical compatibility failures
Designing and executing failure analysis plans at the material component and device levels from analysis strategy through hands-on operation of analytical instruments
Performing chemical and surface characterization using GC-MS FTIR Raman XPS/AES SEM/EDS XRF thermal analysis (TGA/DSC/TMA/DMA) CT X-ray and related techniques and interpreting spectra/data to failure mechanisms
Investigating polymer degradation curing/crosslinking state plasticizer and additive migration residue and contamination sources and chemical attack from consumer-use substances (sebum sweat sunscreen cleaning agents)
Advising design teams on material selection adhesive and coating systems and chemical compatibility during NPI; feeding recurring failure mechanisms back into design SOPs and manufacturing controls
Writing clear evidence-based failure analysis reports that separate confirmed findings from hypotheses and presenting conclusions to multifunctional and executive audiences
Driving implementation of corrective actions with CM/EMS partners to improve product quality and meet reliability specifications and product timelines
Serving as the technical go-to person for chemistry questions in the local FA team and developing new analytical methods standards and more efficient workflows
