  • Experience with hazardous environments (flammables, high voltage, pressurized systems) and safety mitigations
  • Knowledge of fluid systems hardware and instrumentation (pressure, temperature, load cells, relays, solenoids, pneumatics)
  • Familiarity with data acquisition and control systems, PLC hardware, computer networking, and software interfaces
  • Proficiency with PLC and data processing software (Python, MATLAB, LabVIEW)
  • Takes initiative for continuous improvement (not just completing assigned tasks)
  • Flexibility to work in fast-paced environment
  • Attentive to detail and maintain a high level of quality in all work
PERKS & BENEFITS:
  • Comprehensive medical, dental, and vision insurance, including Flexible Spending Accounts (FSA)
  • 401(k) program and transparent stock option plan
