Core Responsibilities

Primary Functions

Develop, document, and meticulously execute detailed test plans and test cases based on hardware specifications and design documents.
Perform comprehensive functional, performance, stress, and regression testing on a variety of hardware products, including PCBs, sub-assemblies, and full systems.
Set up, configure, and maintain complex test environments and lab benches, including the calibration and operation of specialized test equipment.
Identify, isolate, and accurately document hardware and firmware defects with clear, reproducible steps in bug-tracking systems like JIRA or Azure DevOps.
Collaborate directly with hardware design and firmware engineering teams to effectively debug, troubleshoot, and validate resolutions for identified issues.
Conduct thorough root cause analysis of failures discovered during testing, tracing problems from the system level down to the component level.
Read, interpret, and analyze electronic schematics, component datasheets, and board layout files to inform testing strategies and debugging efforts.
Assemble, modify, and perform delicate rework on prototype hardware, including fine-pitch soldering and de-soldering of surface-mount (SMT) and through-hole components.
Validate that hardware performance and electrical characteristics align perfectly with design specifications and industry compliance standards (e.g., FCC, CE).
Develop and maintain automation scripts using languages like Python, Bash, or LabVIEW to improve test efficiency, coverage, and repeatability.
Author and generate comprehensive test reports that clearly summarize test results, analyze data, and present actionable findings to stakeholders.
Manage the flashing of firmware, installation of drivers, and configuration of operating systems (Windows, Linux) on units under test.
Execute environmental and reliability tests, including thermal cycling, vibration, shock, and humidity testing to ensure product robustness.
Design and build basic test fixtures, jigs, and custom wiring harnesses required to interface with and test the hardware effectively.
Verify and validate bug fixes implemented by the engineering team, performing targeted regression testing to ensure no new issues were introduced.
Provide critical feedback on product design and architecture during design reviews, focusing on improving the testability and manufacturability of the hardware.
Maintain a detailed inventory and tracking system for all lab equipment, prototype units, and critical testing assets.
Support manufacturing and production teams by transferring test procedures and assisting with troubleshooting issues on the production line.
Characterize system power consumption, thermal performance, and signal integrity using tools like power analyzers, thermal cameras, and high-speed oscilloscopes.
Stay current with emerging test methodologies, new electronic components, and advanced test and measurement equipment to continuously improve team capabilities.

Secondary Functions

Support the lab management team with equipment procurement, calibration scheduling, and maintaining a safe and organized workspace.
Assist in training junior testers or technicians on standard operating procedures, test methodologies, and equipment usage.
Contribute to the continuous improvement of the team's testing processes, documentation standards, and overall quality strategy.
Participate in cross-functional team meetings, agile sprint planning sessions, and project retrospectives to represent the hardware test function.
