• Coordinate lab space utilization, storage systems, and equipment layouts to maximize efficiency.
• Develop and maintain laboratory standard operating procedures (SOPs), workflows, and best-practice documentation.
• Manage incoming and outgoing sensor samples, ensuring proper labeling, storage, and traceability.
• Execute image quality characterization tests, including resolution, noise, dynamic range, color accuracy, distortion, and uniformity measurements for 2D sensors.
• Perform electro-optical testing using industry-standard analysis tools and custom test setups.
• Evaluate 2D sensor performance against specifications under varying environmental conditions such as temperature, lighting, and vibration.
• Set up, align, and maintain optical test benches, illumination sources, and calibration targets to ensure repeatable measurements.
• Conduct depth accuracy, precision, and repeatability testing of 3D sensing systems, including Time-of-Flight (ToF), stereo vision, structured light, and LiDAR technologies.
• Analyze point cloud quality, including noise levels, fill rates, range accuracy, and field-of-view validation.
• Perform volumetric and multi-plane accuracy testing using calibrated reference targets.
• Evaluate 3D sensor performance under varying environmental conditions and interference scenarios.
• Develop, execute, and continuously improve test plans, methodologies, and procedures for sensor qualification and characterization.
• Collect, analyze, and interpret test data using statistical and engineering principles.
• Generate detailed technical reports summarizing test findings, conclusions, and recommendations.
• Collaborate with engineering teams to define acceptance criteria, investigate failures, and identify root causes.
• Support the development of automated test solutions and scripting tools to improve throughput, consistency, and repeatability.
• Contribute to the design and enhancement of test fixtures, laboratory tools, and overall testing capabilities.
• Apply software testing practices and work with cloud environments, including AWS, as part of sensor test infrastructure and data workflows.
