The role requires disciplined checklist execution, pressure/flow system awareness, clear test-team communications, emergency response, and maintenance of current qualification and system records. Successful candidates will: • Operate, configure, inspect, troubleshoot, and support SVMF breathing-air and ECS equipment within documented qualifications and endorsements. • Complete ECS Operator OJT tasks including K-bottle installation and changeover, manifold and pressure checks, compressor-cart operation, ECS console preparation, air/water connections, communications checks, airflow and cooling-water control, chiller operation, gauge interpretation, shutdown, and emergency actions. • Verify breathing-gas purity, cleanliness and contamination controls, pressure-system certification status, relief-device status, gauges/flowmeters, calibration, sampling, and required QA/verification before human use. • Perform authorized operator maintenance and logbook activities for compressors, drains, filters, hoses/fittings, gauges/flowmeters, gas monitors, and associated ECS equipment; route work outside operator scope through approved engineering/controlled-work processes. • Support suited training under Test Director control and respond immediately to off-nominal conditions including low-flow/pressure anomalies, loss of primary air source, contamination concerns, communications loss, facility emergencies, or medical emergencies. • After separate Test Director qualification, conduct event briefings, verify test-team readiness and required checklists, direct pressurized event activities, manage anomalies, and place an event in a hold or terminate condition when required for safety. • Coordinate with suit technicians, suit engineers, instructors/test conductors, communications personnel, facility management, engineering, and other test-team members. • Maintain required event checklists, qualification records, equipment logs, calibration/maintenance records, and anomaly documentation. • Support multiple suited-program configurations such as ISS, CST/Boeing, Orion, EHP, and other assigned programs after completing the applicable qualification. • Maintain qualification currency through recurring ECS training, emergency drills, system-specific delta training, suited-event proficiency, and Test Director currency requirements when qualified. • Demonstrate strong situational awareness, stop-work judgment, concise communication, and the ability to perform safely in time-critical human-rated operations. • Operate forklifts, manlifts, overhead cranes/rigging, POGO, PABF, scaffolds, or other specialized equipment only when individually qualified and endorsed. Job Requirements • High school diploma or equivalent and a minimum of 2 years of operations/maintenance or directly related technical experience to meet SVMF technician candidacy requirements.
