Job Summary: At LG Energy Solution Arizona, Inc., the Engineer II - Analysis will play a key role in conducting failure analysis to identify the root causes of product failures and safety issues related to lithium-ion battery cells. Working in a laboratory and analytical environment, this role evaluates internal, external, and returned samples to determine the source of defects across supplier, production, and finished goods stages. The Engineer II conducts detailed investigations and implements analysis methods to support root cause identification, prepares technical reports, and communicates findings to cross-functional teams to support corrective actions, prevent future defects, and improve overall product safety and reliability.
Responsibilities:- Analyze structural and design safety risks of lithium-ion battery cell systems using data-driven evaluation methods and advanced analytical tools.
- Conduct battery failure investigations using precision analysis equipment to identify root causes of product defects, safety concerns, and field failures.
- Evaluate returned products, buyback samples, and adjacent cells to determine failure propagation and contributing factors impacting battery performance and safety.
- Conduct reproducibility experiments to validate suspected failure mechanisms and confirm root causes of field quality issues.
- Maintain operational readiness and perform basic maintenance of laboratory analysis equipment to ensure accuracy, reliability, and efficient utilization.
- Perform advanced data analysis and prepare technical reports communicating root causes, findings, and recommended corrective actions to engineering and quality stakeholders.
- Coordinate with cross-functional teams including Engineering, Quality, Customer Service/Warranty teams, suppliers, and global headquarters to support investigation and resolution of product issues.
- Maintain laboratory organization and compliance with 5S3R standards (Sort, Set in Order, Shine, Standardize, Sustain; Right Location, Right Quantity, Right Container) to ensure a safe and efficient analysis environment.
Qualifications:- Bachelor's degree in Engineering or a related technical field.
- 3+ years of experience in quality engineering, failure analysis, or reproducibility testing within an automotive or manufacturing environment (internship or co-op experience may be considered).
- Experience conducting failure analysis of fire-related components.
- Experience using analytical and non-destructive testing equipment such as 3D CT scanning, SEM/EDX, ion milling, mechanical polishing, or optical microscopy.
- Knowledge of metrology, measurement systems, and calibration processes within a laboratory or manufacturing environment.
- Experience working in cross-functional teams within a manufacturing or laboratory environment.
- Ability to work flexible hours as needed to support investigations, testing activities, and collaboration with global teams.
Skills:- Knowledge of IATF and ISO standards.
- Experience using Minitab, Six Sigma methodologies, and 8D problem-solving approaches.
- Strong verbal, written, and presentation communication skills.
- Strong critical thinking abilities and an analytical approach to problem solving.
- Proficiency in Microsoft Office Suite and Minitab for data analysis and reporting.
- Strong data analysis and statistical problem-solving capabilities.
