On-Call and Work Schedule 

• Participate in a rotational 24/7 on-call schedule; rotation frequency: bi-weekly 

• Required alert acknowledgement time: 15 minutes; required facility arrival time: 60 minutes. 

• Maintain reliable communication and transportation to satisfy approved response requirements. 

• Overtime, extended shifts, nights, weekends, and holidays may be required to maintain test continuity. 

• All hours worked, including after-hours remote monitoring, troubleshooting, and callouts, must be accurately recorded and compensated according to applicable law. Standby-time and callout policies require People Operations review. 

Physical Requirements and Work Environment 

• Work in test cells with noise, heat, vibration, exhaust, fuel, and industrial fluid exposure; use required PPE and hearing protection. 

• Lift and handle engine components within approved safe-lifting limits; specified lifting requirement: up to 50 lbs. Use hoists, engine stands, or team lifting for heavier loads. 

• Stand, bend, kneel, climb, and work in restricted spaces for extended periods as needed. 

• Work in proximity to rotating machinery, high-pressure systems, flammable fuels, and hot surfaces. 

• Essential functions may be performed with or without reasonable accommodation.
