Responsibilities

Design, develop, execute, and maintain automated test scripts to stress system and firmware limits across robotic and embedded subsystems.
Interface with subsystem APIs to collect error logs, telemetry data, diagnostics, and performance metrics.
Instrument hardware with electrical and thermal sensors to capture and analyze performance data under various operating conditions.
Execute reliability and validation test plans and generate detailed reports for cross-functional engineering stakeholders.
Monitor firmware logs for assertion failures, anomalies, and performance degradation across extended test cycles.
Track communication bus packet loss, timing issues, sensor drift, and driver performance to identify failure trends and subsystem degradation.
Perform statistical analysis on telemetry and test data to identify reliability risks and support engineering decision-making.
Partner with Failure Analysis (FA) engineers to validate repaired, rebuilt, or reworked subsystems.
Support design and manufacturing teams by feeding reliability data into risk mitigation and continuous improvement activities.
Operate, maintain, and improve test infrastructure including environmental chambers, logic analyzers, bus analyzers, power-cycling rigs, and programmable electronic loads.
Follow Business Technology policies to protect sensitive data and reduce information security occurrences.
