Job Description of Principal Reliability Engineer of ON Semiconductor at Taiwan
We are now looking for a Principal Reliability Engineer. The position is an individual contributor role, working with the NPD cross functional teams for NPD projects and BE Ops/PKG/TE for MP projects.
- For NPD projects, the engineer is to work with Design, Technology, PI, PE, TE, and PKG to develop, to document and to execute the reliability strategy and qualification plans for new product development. Participate weekly NPD meetings with cross functional teams.
- For building-in reliability & quality into NPD products, the reliability engineer gets involved in package & technology development, design of experiments (DOE), material and process characterization & validation & reliability evaluation & process and product qualifications… Results from these DOEs & process characterization & reliability evaluation will be employed to improve the quality and reliability of products.
- In case of failures happening during Qual stress tests, the engineer needs to perform 1st level reject disposition and failure analysis for reliability failures and teamwork with Product Engineer, Sub-con & Foundry, Packaging, Technology, and Design teams for root cause analysis and request corrective or preventive actions if applicable.
- Work closely with PE and TE to review the NPD test program development to ensure Test Quality in NPD process & release
- Participate in Product Validation Process and provide engineering inputs to improve NPD Quality & Reliability
- Participate in Product Yield Improvement Process and provide engineering inputs to improve NPD Yield& Quality & Reliability
- Lead the Qualification Readiness Check in the cross-functional areas
- Be responsible for working with PE on drift analysis of the Qualification tests, and electrical data analysis of the qualification rejects
- The engineer is to work with BE Ops, PKG/Assembly, and TE on Qualification of MP changes; to develop, document and to execute the reliability strategy and qualification plans for MP changes. Participate BE ops meetings with cross functional teams. Support Reliability functions for RMA customer returns.
- The job requires the engineer to participate in assessment of Qual Material Readiness and Test program readiness required to release qualification materials into qualification process. The engineer should write clear and complete Qual readiness report and risk assessments, and also reliability qualification reports.
