Job description

Our Mission
SPAN is enabling electrification for all
We are a mission-driven company designing, building, and deploying products that electrify the built environment, reduce carbon emissions, and slow the effects of climate change.
  • Decarbonization is the process to reduce or remove greenhouse gas emissions, especially carbon dioxide, from entering our atmosphere.
  • Electrification is the process of replacing fossil fuel appliances that run on gas or oil with all-electric upgrades for a cleaner way to power our lives.
At SPAN, we believe in:
  • Enabling homes and vehicles powered by clean energy
  • Making electrification upgrades possible
  • Building more resilient homes with reliable backup
  • Designing a flexible and distributed electrical grid
The Role

SPAN is seeking an experienced and driven hardware test engineer who can contribute to all stages of development. 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.

In this position, you will be:

  • 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.
