We are seeking an experienced EE Validation Engineer to support hardware validation of next-generation smart glasses, working closely with the validation lead. In this role, your primary focus will be monitoring validation progress, reviewing CM test reports, analyzing failures, and coordinating with EE design partners to drive issues to closure. You will also guide CM engineers on measurement procedures and perform hands‑on PI/SI debug when needed.

While you must possess strong hands‑on measurement skills, the majority of your time will be spent interpreting data, tracking issues, and ensuring problems are resolved efficiently. You will not own final validation decisions, but you are expected to be technically strong enough to flag risks, recommend actions, and keep execution on track under the lead's direction.

• Review CM‑generated validation reports and verify data quality.
• Ensure pass/fail criteria are applied correctly.
• Identify anomalies and investigate validation failures.
• Determine whether issues are caused by measurement errors, design defects, or manufacturing quality.
• Collaborate with EE design teams to present findings and support root‑cause analysis.
• Track issues through resolution and confirm fixes are validated.
• Coordinate across EE, layout, firmware, and CM teams to keep issues moving.
• Maintain issue trackers and provide regular status updates to the Validation Lead.
• Monitor validation progress against project milestones.
• Escalate risks, blockers, and schedule concerns proactively.

• Develop clear Standard Operating Procedures (SOPs) for validation testing.
• Train CM engineers and technicians on proper measurement techniques.
• Guide probe placement, fixture usage, and data collection methods.
• Define probe points and create annotated layout markups for testing.
• Provide technical support when unexpected measurement results occur.
• Establish acceptance criteria and escalation processes aligned with validation requirements.

• Perform advanced PI/SI measurements during prototype bring‑up and validation.
• Validate CM measurement setups through correlation testing.
• Debug complex or intermittent hardware issues that require senior engineering expertise.
• Develop new measurement methods and fixtures for challenging validation scenarios.
• Support prototype characterization and hardware bring‑up during build phases.

• Characterize DC‑DC converters (line/load regulation, efficiency, transient response, output ripple/noise).
• Validate power sequencing and timing against IC specifications.
• Evaluate power rail stability under varying load conditions and perform current profiling.
• Validate battery charging circuits, including charge profiles, protection features, and thermal limits.
• Understand Power Distribution Network (PDN) concepts such as ground bounce, decoupling, and voltage droop.

• Perform measurements on high‑speed interfaces (MIPI CSI, SPI, I2C, I2S/PDM, USB, UART).
• Analyze signal quality, including…
