The role

We are seeking a Senior Sensor Reliability Engineer who will ensure our sensor systems meet the highest performance and durability standards under real-world conditions. We are looking for someone passionate about identifying reliability risks, developing robust testing strategies, and solving complex hardware challenges. You will work cross-functionally to assess sensor designs, implement rigorous test methodologies, and help optimize sensor performance for long-term field deployment.

How you’ll contribute

• Own the sensor reliability function, ensuring sensor systems meet stringent performance and durability requirements through advanced reliability testing.

• Apply Design for Reliability (DfR) best practices to proactively identify and mitigate potential failure risks in sensor designs.

• Develop and execute comprehensive test strategies to uncover failure modes, predict field failure rates, and validate off-the-shelf components in sensor systems.

• Translate FMEA-identified risks into sensor-specific test procedures with well-defined objectives and pass/fail criteria.

• Plan and execute Design of Experiment (DOE) campaigns to understand and mitigate failure mechanisms in sensors.

• Design and refine test setups to evaluate sensor reliability under environmental, mechanical, and operational stress conditions, including shock, vibration, and thermal cycling tests.

• Collaborate with cross-functional teams to integrate reliability findings into the sensor design and manufacturing process, ensuring robust sensor performance in the field.

• Drive failure analysis investigations to resolve issues found during testing and field deployment.

• Automate sensor testing processes and analyze performance data using tools like Python, JMP, or MATLAB to extract actionable insights. 

What you need to succeed

• Bachelor's degree in Electrical Engineering, Mechanical Engineering, Materials Science, or related field.

• 5+ years of experience in reliability or quality engineering, with a focus on sensor systems.

• Hands-on experience developing and validating sensor systems, particularly optomechanical products.

• Strong knowledge of the physics of failure for electronic and optoelectronic components as applied to sensors.

• Experience designing sensor test setups for environmental, mechanical, and operational stress conditions (e.g., shock, vibration, thermal testing).

• Familiarity with reliability techniques such as FMEA, Weibull Analysis, Statistical Process Control (SPC), and Monte Carlo simulations.

• Proficiency in automating sensor testing processes and defining test conditions, acceleration factors, and pass/fail criteria.

• Understanding of hardware and firmware interactions critical to sensor performance and reliability.
