life360 Hardware Test Technician at Life360 to run the hardware test lab and support engineering for reliable consumer device shipping. Responsible for test execution, soldering, rework, quality and returns analysis, and lab logistics.
Responsibilities
Run the Test Lab Day to Day
Set up devices and execute the test sequences the engineers define — spanning electrical and power, functional, wireless, environmental, and product-reliability testing — logging results cleanly and consistently.
Watch for anomalies and flag them early, with enough detail for the engineers to act on.
Keep test records and data organized so results are easy to trace and trust.
Own the facility: keep equipment working and calibrated, maintain stock of parts, drive purchase of new equipment and capabilities, and manage services and deliveries.
Drive Quality and Returns Analysis
Triage and root-cause customer and field returns — reproduce the failure, find the likely cause, log and trend what you see, and route deeper analysis to the engineers.
Run defect analysis on units in development and production, and help hold the quality bar.
Connect production quality and customer quality, tying what fails in the field back to what we build.
Build, Solder, and Maintain
Build test fixtures, jigs, and cabling to hold and connect devices under test.
Do precise hand soldering and small-board rework: this is core to the products we make.

Required
Several years of hands-on experience in an electronics or hardware test lab; consumer electronics is a plus.
Associate degree in electronics, electrical engineering technology, or a related field — or equivalent hands-on experience.
Self-directed and organized, with the judgment to run a lab day to day without close supervision.
Careful and safety-minded, with strong documentation and data-logging habits.
Clear communicator who shares findings and flags problems early, in a form engineers can act on.
Curious about failures, following a breakage to its root cause.
Some familiarity with AI tools and a willingness to learn — you'll be encouraged to use AI (e.g., Claude Code) to build test harnesses and automate testing. Deep AI experience isn't required.
Hands-On Lab Skills
Excellent hand soldering and small-board rework — a strength, not just a familiarity. Capable with BGA, QFN, and fine pitch component packages down to 0201/01005, and of complex rework and PCB modifications.
Comfortable with standard bench instruments: oscilloscopes, multimeters, power analyzers, and power supplies.
Test-fixture and cable building, with the mechanical aptitude to make things fit and work.
Light scripting for data capture and test automation, and the test-fixture design to support it.
Preferred
Broader product-reliability testing — tumble, mechanical shock, and random or sine vibration.
Accelerated and environmental stress — thermal shock, HAST (damp heat), and accelerated-life screens (HALT/HASS).
Ingress and durability — water and dust ingress (IPX7/IP68), salt-fog and corrosion, button and connector life-cycling, and chemical or materials exposure.
A broader mechanical background — comfort across a range of mechanical and environmental test rigs. Knowledge of ASTM/ISO test standards would be a plus.
Over-the-air (OTA) RF testing in an anechoic chamber (TRP/TIS), and GPS/GNSS testing with a constellation simulator.
Familiarity with pre-compliance or certification testing (FCC, UL, IEC).
