About this role

9 Mothers is seeking an R&D Test Engineer to lead high-speed imaging operations for counter-drone and firearms testing. You'll design test setups, operate specialized cameras, extract kinematic data from footage, and deliver quantitative analysis that drives engineering decisions in a fast-paced, mission-critical environment.

What you'll do

  • Plan and execute high-speed imaging campaigns for mechanism analysis and ballistic pattern capture
  • Design test setups including camera positioning, field of view, and trigger architecture using pressure sensors and acoustic triggers
  • Operate Photron Fastcam and Phantom high-speed camera systems with appropriate frame rates and exposure settings
  • Extract kinematic data (displacement, velocity, acceleration) from footage using motion analysis software and calibration techniques
  • Produce clear, data-driven reports with uncertainty quantification for mechanical engineers and program leads
  • Develop test plans, procedures, and data reduction protocols; manage test infrastructure growth

What they're looking for

  • High-speed imaging and camera operation (Photron, Phantom systems)
  • Motion analysis software (PFA, ProAnalyst)
  • Test design and experimental methodology
  • Kinematic data extraction and measurement uncertainty analysis
  • Trigger circuit design and sensor integration (TTL, pressure, acoustic)
  • Lighting design for high-speed scientific imaging
  • Technical report writing and data documentation
  • Mechanical troubleshooting and fixture design
