Job description

• Define mechanical verification and validation methodologies for each of the different systems by working with researchers, architects and product design teams
• Perform core function for verification of thermal, vibration, mechanical stress testing, etc
• Define and track detailed test plans for the different modules and top-level systems
• Define, architect, design and drive implementation of scalable test infrastructure and custom mechanical test fixtures
• Keep track of coverage metrics and bugs encountered and resolutions
• Own execution, interpretation and reporting of mechanical system-level verification and validation work
• Drive FMEA, failure analysis, tolerance analysis, gauge R&R, and the GD&T activities supporting product scalability in close collaboration with process, manufacturing and REL teams
• Support system bring-up and debug activities
• Perform analysis on large datasets to summarize results and clearly communicate test plans results
• Manage external vendors for test fixture development, execution and data collection and review vendor test reports and ensure compliance with requirements.
• Design, build, and qualify electro-mechanical test fixtures and rigs — motorized/actuated stages, load and displacement fixtures, automated cycling and don/doff testers, vibration and drop setups
• Implement machine I/O and control: sensor and actuator wiring, motion control (steppers/servos), microcontrollers/PLCs, and digital/analog I/O interfaces between test hardware and host software
• Apply statistical rigor: DOE, sample size and confidence justification, Weibull/reliability analysis, GR&R, SPC
• Evaluate, specify, and justify capital test equipment; manage vendor technical evaluations, quotes, acceptance testing, and commissioning
• Provide technical guidance and mentorship to other engineers and technicians, and raise the team's overall test-methodology bar
