Day-to-Day Responsibilities
Write test plans and procedures from the product specification, covering functions, power use, temperature and durability.
Set up test benches with oscilloscopes, multimeters, signal generators and custom fixtures.
Run tests on prototypes and production units, record readings and mark each unit as pass or fail.
Test wireless and sensor functions such as Bluetooth, Wi-Fi, GPS, battery charging, displays, microphones, cameras and heart-rate sensors.
Find the root cause of failures by working with design and firmware teams, and recommend fixes.
Write test reports and track defect trends so that quality problems are spotted early.
Automate repeated checks with scripts in Python or LabVIEW to speed up production testing.
