Sr. Electro-Mechanical Engineer 100% Remote

Responsibilities
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
Required Qualifications
Bachelor's degree in Mechanical Engineering, Electro-Mechanical Engineering, Mechatronics, or a related technical field, and/or equivalent practical experience
8+ years of experience in electro-mechanical engineering with a demonstrated track record in mechanical validation, verification, or reliability test
Demonstrated experience authoring and executing mechanical validation and reliability test plans (e.g., drop, vibration, fatigue/life cycling, environmental, HALT/HASS/ALT) with defined acceptance criteria
Hands-on experience designing and building test fixtures and instrumented rigs, including sensor selection, mounting, calibration, and measurement-uncertainty assessment
Proficiency with Python for test automation, instrument control, and data analysis (e.g., NumPy/pandas or equivalent)
Experience with I/O and data acquisition: analog/digital I/O, DAQ hardware, serial interfaces (SPI/I2C/UART/USB/Ethernet), sensor signal conditioning, and motion control
Experience interpreting mechanical drawings and applying GD&T, and using metrology and inspection equipment (CMM, optical/vision measurement, 3D scanning)
Experience applying statistical methods to test design and interpretation (DOE, sample size justification, Weibull, SPC)
Preferred Qualifications
MS in Mechanical Engineering, Mechatronics, or a related field
Experience validating consumer electronics products, particularly compact or highly integrated form factors
Experience with dynamic and environmental test methods and the standards that govern them (e.g., vibration, shock, transport, and environmental exposure standards)
Experience with optical, non-contact, or full-field measurement techniques for displacement, deformation, or motion
Experience with instrumentation for force, pressure, or load distribution measurement
Experience with FEA or simulation-to-test correlation
Experience building automated test cells and the supporting software infrastructure (test frameworks, databases, dashboards)
Experience owning capital equipment specification, vendor selection, and lab build-out
Experience mentoring engineers and technicians and standardizing test methods across teams
Develop Python-based automation for test control, data acquisition, and analysis; build reusable analysis pipelines and dashboards so results are reproducible rather than one-off
