The Developer (Product Characterization) position at IBM Corporation in Poughkeepsie, NY involves analyzing high-speed I/O signals from on-chip IP in various forms including wafers, modules, and systems. The role supports end-to-end analog circuit characterization for IOBIST (Input Output Built-In Self-Test) and requires defining and enhancing test methodologies to verify I/O functionality. The developer will provide essential instructions to guide the I/O team, aiming to improve yield and performance for future nano technologies. Coordination with test and design teams is crucial for performing corrective actions with semiconductor fabrication suppliers. The position also entails presenting I/O product analysis to microprocessor development and production teams, covering aspects such as test, design for test, characterization, yield, and quality. Additionally, the developer will work with the production manufacturing team to address any I/O issues during module builds, characterize I/O circuits, and identify process and design issues early in the product development cycle to drive improvements in yield and product quality. The role includes characterizing Analog Circuit IOBIST signatures on IBM microprocessor products, owning the Specification sheets (EMTS) for the analog circuit across the product suite, and developing software applications for the IP Char product engineer team to enhance productivity and analytics for faster identification of yield and quality issues. Regular presentations of detailed reports to stakeholders, test teams, design teams, and product engineering are also part of the responsibilities, along with delivering analysis and characterization on field returns related to I/O failures across products and generations.
