Implementations are done by way of Engineering Change Orders (ECOs), Special Build Request (SBRs), changes to Standard Operations Procedures (SOPs) and process deviations on parts, processes and software. • Perform failure analysis on Laser Phosphor Display (LPD) tiles (building blocks of a video wall) that have failed at customer sites or incoming finished goods from CM (that failed after final test at US) to understand root cause and feedback to the manufacturing process for improvements. In particular I look mostly at failures related to servo loops of LPD tiles. • Work with software team in US to implement production software changes that would improve production yield and resolve quality issues. On a per need basis I would modify production software myself on engineering mode phase of a particular task /project. From March 2015 to Present (8 months) San Jose, CASenior Staff Engineer System Design @ • Program lead responsible for yield, quality and test time improvements on new programs to the Self Servo-Write (SSW) manufacturing process. Duties included the generation of program formats, tuning of servo loops (design of controllers and estimators), and selection and maintenance of appropriate embedded firmware code base. • Coded, tested and debugged SSW embedded firmware as part of bring up of new process features and improvement of existing ones. • Compiled and released firmware packages for assigned programs that will go through the SSW process (both engineering and production mode). This was done both during engineering phase in US as well as part of program transfer to factories overseas. • Performed Failure Analysis (FA) on hard drives that failed to complete the SSW process to determine possible failure root causes and potential solutions to be incorporated into the process firmware. • Created tools using MATLAB scripting language that would help to support the FA process and development of new features. • Participated in requirement reviews, design reviews and code reviews for new features that would become part of the SSW process embedded firmware. • Generated and coordinated training material for new group hires.
