  • Validate measurement precision and accuracy; procure or design specialized fixtures and sensors as needed
  • Create schematics and CAD models of test setups and facilities
  • Define standard processes and workflows for prototype, qualification, and production-grade testing
  • Provide subject matter expertise on test methods, including mentoring teammates
  • Participate in root cause investigations and implement corrective actions to prevent repeat failure


Basic Qualifications:
  • Bachelor's degree in physics or an engineering discipline
  • 2+ years of hands-on test engineering experience

Preferred Skills & Experience:
  • Master's degree or higher in mechanical or aerospace engineering
  • Experience designing and building test rigs and executing thermal and mechanical tests
  • Experience with LabVIEW, Simulink, or similar test software
  • Experience testing thermal management or heat-rejection systems, or vacuum-relevant components
  • Experience in mechanical, durability, or materials testing
  • Leadership experience on a project or research team
  • Strong project management and cross-disciplinary communication skills
  • Demonstrated track record of high-impact technical contributions
  • Experience with part inspection technologies (micrometers, CMM, white light scanning, etc.)
  • Knowledge of PLM, ERP, and related manufacturing systems
  • Strong Python or general programming experience


Additional Requirements:
  • Ability to work long hours and weekends as necessary to support critical milestones
  • Ability to lift 25 lbs; role may require standing, climbing, bending, grasping, sitting, pulling, pushing, stooping, stretching, and carrying
