Senior Scientist

Senior Detector Scientist, Reliability

Redlen’s Product Performance Department is dedicated to ensuring our detector modules meet the highest standards of the performance, reliability and application suitability. The Reliability Team focuses on characterizing and reporting on failure modes, failure rates and lifetimes of the PCCT detectors across the entire product lifecycle – from semiconductor material development to device integration. Acting as a cross-functional bridge within the organization, the team conducts Sensor-, Mini Module-, Detector Module- oriented HALT, ALT and other characterization and reliability-specific testing, along with in-gantry data analysis, driving initiatives that align with Redlen’s reliability advancement objectives. Their work spans emerging technologies, including semiconductor material growth, device fabrication, device physics, detector module engineering, advanced photon-counting ASICs, and attachment/interconnect technologies.

Key Responsibilities:

Detector Performance

• Explore, determine, define, and establish key attributes of x-ray detector performance focusing on high-flux operations relevant to photon-counting computed tomography (PCCT).
• Develop and maintain sensor-, minimodule-, and detector-level experimental methodologies. Develop and refine analytical methods, models, and interpretation frameworks. Write-up and communicate results, including to internal and external customers.

Device Reliability

• Own execution and continuous improvement of advanced experimental and analytical aspects of device reliability, including component-level investigations and development of a consistent framework for reliability-specific analysis and reporting, lifetime modeling, finding the material and process factors influencing failure mechanisms and failure rates.
• Develop novel testing and aging protocols for PCCT detectors, including test vehicles for next generation products. Define technical requirements and provide technical leadership throughout the design, development and implementation of reliability test vehicles in close collaboration with Test SW and HW engineers.
• Own the reliability requirements, scientific validity, and fitness for purpose of reliability test systems and infrastructure. Partner with Test Software and Hardware Engineering on their design, implementation, troubleshooting, and continuous improvement.
• Support Test function in troubleshooting complex existent test box, test tank, test software, environmental chamber, and other issues.

Cross-functional work

• Support New Process Introduction and Technology Transfer teams by identifying detector performance and reliability risks associated with new or modified processes, defining and executing validation plans, and providing data-driven recommendations on process equivalency, technical risks, and readiness for implementation.
• Own defined performance and reliability verification methodologies in support of internal development programs and external customer requirements. Develop verification strategies, acceptance criteria, and test methodologies. Interpret results and provide technical recommendations supported by experimental evidence and statistical analysis.
• Support Manufacturing, Product Engineering team to monitor and analyze key product performance metrics that influence yields at sensor and module level. Develop methodologies to isolate and characterize the root cause(s) of process variations by analysis of passive data from manufacturing and by designed experiments. Provide subject matter expertise and technical guidance based on established methodologies and experimental evidence.
• Provide technical support to external customers, including interpreting and communicating experimental results, assessing potential impacts on detector- and system-level performance. Collaborating with customer technical teams to investigate issues and develop potential solutions.
