Product Engineer: Yield & Test Analytics for Semiconductors

u-blox AG; Schweiz; Hybrid; CHF 90.000 - 130.000; Vollzeit

Zusammenfassung

u-blox AG, headquartered in Thalwil, Switzerland, is a fabless semiconductor company shaping automotive, industrial, and consumer markets with advanced positioning and short‑range wireless tech.

The Product Engineer role bridges chip design, FAB, assembly, and test operations to ensure high yields, zero‑defect quality, and cost‑effective mass production. You will manage subcontractors and analyze test data to drive improvements.

Qualifikationen

• Bachelor’s or Master’s degree in Electrical Engineering or related technical field.
• Hands‑on experience with semiconductor production test data analysis tools (e.g., YieldMan, Exensio/PDF Solutions, Galaxy Semiconductor, JMP, Spotfire).
• Solid understanding of database structures (SQL, relational databases, STDF data parsers) and proficiency in querying/manipulating structured test data.
• Strong proficiency in statistical methods (SPC, Gauge R&R, ANOVA, Six Sigma).
• In‑depth knowledge of wafer fabrication, assembly processes, and test flows (Wafer Sort and Final Test).
• Structured, precise, and independent approach to analytical problem‑solving.
• Good team player with excellent communication skills, both verbal and written
• Fluent in English; German language skills are a plus

Aufgaben

• Execute, qualify, and release production test programs (Wafer Sort & Final Test) at global OSATs.
• Analyze large-scale production test datasets to identify yield trends, perform Pareto analyses, and detect parametric outliers.
• Maintain, query, and structure yield databases to streamline data extraction, build tracking dashboards, and enable automated reporting workflows.
• Drive root‑cause identification and rapid resolution for yield drops, low‑yield lots, equipment excursions, and electrical failure analysis (EFA) on the production floor.
• Apply Statistical Process Control (SPC) and Six Sigma methods to monitor device limits, Cpk/Ppk metrics, and spatial wafer maps.
• Act as the technical liaison connecting FAB, assembly/packaging houses, and test operations to optimize yields and reduce test times.
• Collaborate closely with Test Development, Logistics, and Quality teams to deliver compliant products on time while ensuring strict automotive and industrial quality standards.
