• Develop validation plans for IP and chip‑level test cases from datasheet and in consultation with design and systems engineers
• Develop test cases and customer usage models that may violate the assumptions of designers and systems engineers
• Develop automated test framework, regression test suites in Python, MATLAB and/or LabVIEW to optimize validation efficiency
• Work with validation peers to implement standard methodologies and continuous improvements to Cirrus Logic validation methodologies
• Collaborate closely with IC Design engineers, System engineers and Application engineers to understand requirements and use cases
• Perform circuit simulation to support board design
• Design PCB schematics and collaborate with layout engineers to review board layouts before being released for fabrication
• Debug analog/digital silicon issues, board issues and Validation software/hardware tools issues
• Analyse test results and identify failures/defects using business intelligence tools such as Spotfire

Required Skills and Qualifications
