About The Position

Cirrus Logic is seeking a Senior Validation & Characterization Engineer for its Austin team. The role involves hands-on work bringing complex mixed-signal ICs from first silicon through production release, across lab validation, automation, data analysis, and silicon debug. Products include audio CODECs, amplifiers, haptics and sensing, power delivery, and battery management. The engineer will collaborate with design, systems, product test, applications, and reliability teams.

Requirements

• Bachelor’s degree in Electrical or Computer Engineering.
• At least 5 years of relevant industry experience.
• Hands-on experience with silicon validation, characterization, or post-silicon debug of mixed-signal ICs.
• Understanding of mixed-signal blocks such as ADCs, DACs, PLLs, amplifiers, regulators, and sensors.
• Experience developing automated test software; Python is preferred.
• Experience using laboratory instrumentation.
• Effective data-analysis and problem-solving skills.
• Effective communication skills and experience working across engineering teams.
• Must be able to access technical data without requiring an export license; Cirrus Logic is unable to sponsor or obtain export licenses for this role.

Nice To Haves

• Familiarity with PXI-based systems.
• Experience validating audio or power-management ICs.
• Experience with digital interfaces such as I2C, SPI, I2S, TDM, or SPMI.
• Experience using embedded firmware or lab-automation platforms.
• Experience correlating validation results with production test.
• Experience providing technical leadership or mentoring junior engineers.

Responsibilities

• Perform hands-on silicon validation and characterization from first silicon through production release.
• Contribute to test plans and coverage for analog, digital, and mixed-signal blocks.
• Build and improve automated lab setups and test software using Python, PXI systems, and bench-top or lab instrumentation.
• Design validation boards and review schematics and layouts.
• Measure and analyze performance, margins, robustness, and corner conditions.
• Partner with engineering teams to debug silicon issues, identify root causes, and connect validation results to production test limits and guard bands.
• Strengthen validation methods, documentation, and lab efficiency.
• Present findings clearly and provide technical guidance to junior engineers.
