Test Engineer

ONiO builds microcontrollers that run without batteries — but that’s not the point. Our chips harvest ambient energy — light, heat, RF — and just work. No wires. No recharging rituals. No maintenance loops. We don’t believe batteries are evil. We just don’t assume they’ll always be there. Our first chip, ONiO.zero, is a wireless microcontroller built from scratch to run on harvested energy. It cold-starts from under a microwatt. It runs BLE and other radios.

Help us verify the world’s most energy-efficient microcontrollers. We’re looking for a Test Engineer to own wafer, packaged, and system-level testing of our batteryless SoCs.

Responsibilities

  • Develop and execute test plans for wafer-level, packaged, and system-level testing
  • Build automated test programs (ATE platforms like Teradyne/Advantest or custom setups)
  • Generate test patterns and validate functionality, performance, and parametrics
  • Debug test failures and work closely with design, DFT, and product teams
  • Support bring-up and correlate silicon from lab to production
  • Analyze test data for yield, margin, and process variation insights
  • Develop test hardware: load boards, probe cards, sockets
  • Document procedures, results, and support test transfer to mass production
  • Participate in DFT reviews and improve test coverage
  • Support production ramp, test time reduction, and cost optimization

Requirements

  • Semiconductor test experience (bench or ATE) — 2+ years preferred
  • Test scripting/programming (Python, C/C++, LabVIEW, or ATE languages)
  • Strong understanding of analog/digital measurements and lab instrumentation
  • Familiarity with IC test methodologies: parametric, functional, boundary testing
  • Knowledge of DFT (scan, BIST, JTAG) is a plus
  • Degree in Electrical or Computer Engineering or related field
  • Comfortable analyzing large datasets and working in lab environments
  • Strong debugging skills and attention to detail

Bonus

  • Yield improvement and test limit optimization experience
  • Test infrastructure background for high-volume manufacturing

Benefits

  • Competitive salary and insurance, health & pension benefits
  • Stock options — skin in the game
  • The chance to shape real, cutting-edge products
  • Fast-paced, diverse, design-forward environment
  • Work-life balance, family-friendly policies

We know talent doesn’t come in neatly shaped lists. If you don’t tick every box but this sounds like your kind of challenge — apply anyway. We care about capability, curiosity, and attitude over perfection.
