Desirable

• In this role, you will rely on your past experience to develop a comprehensive hardware test program for new products and support any reliability issues that arise in the field
• You will work with the electrical, mechanical, and systems teams to implement test plans, build out our in-house testing capabilities, and work with outside labs as needed
• Contributing to the design-for-reliability and validation strategy for SPAN’s future electrical products
• Defining and executing test plans to validate performance, reliability, and compliance of circuit boards and system-level electronics (e.g. power converters, energy metering, and communication interfaces)
• Developing automated test setups using Python and Linux command-line tools for data collection, logging, and analysis
• Collaborating with hardware design engineers to translate design requirements into detailed test specifications
• Performing electrical validation and stress testing, including power cycling, fault injection, communication robustness, and analog/digital signal characterization
• Analyzing test data, applying statistical methods where appropriate, and presenting clear, actionable findings to design and leadership teams
• Working hands-on in the lab: setting up instrumentation, soldering/debugging boards, and executing electrical tests
• Supporting regulatory, compliance, and safety testing (FCC, UL, IEC, NEC)
• Driving root-cause analysis of test failures and collaborating with cross-functional teams
