Core Responsibilities

Primary Functions

Execute standardized engine start-up, run, and shutdown procedures for jet engines and auxiliary power units (APUs), ensuring adherence to OEM checklists, test plans, and facility-specific safety protocols.
Conduct pre-run inspections of engine mounts, fuel and oil supply lines, electrical connections, intake and exhaust systems, and instrumentation to verify readiness for engine operation and to prevent in-run failures.
Monitor live engine parameters (N1/N2, torque, EGT/Jet Pipe Temp, fuel flow, oil pressure, vibration levels, and bleed air) during idle, acceleration, cruise-sim, and shutdown sequences and take corrective actions when readings deviate from acceptable limits.
Start and stabilize engines on ground test cells under the supervision of engineering staff, controlling throttle schedules and fuel control settings to reproduce test points for performance validation or troubleshooting.
Perform controlled engine acceleration and deceleration profiles, recording time-based performance data and capturing high-fidelity instrumentation outputs for post-run analysis by propulsion engineers.
Execute safety-critical checks and enforce exclusion zones, fire watch protocols, and emergency shut-down (E-Stop) procedures during all engine runs to protect personnel, equipment, and test facilities.
Troubleshoot abnormal engine behavior in real time—identifying causes such as fuel contamination, ignition anomalies, compressor stalls, surge events, or sensor failures—and initiate appropriate corrective or abort actions.
Coordinate run plans and test objectives with propulsion engineers, mechanics, quality assurance, and safety officers, documenting deviations, test conditions, and environmental variables for traceability.
Operate and calibrate test cell control consoles, data acquisition systems (DAQ), digital oscilloscopes, and engine control interfaces; ensure all sensors and transducers are functional and within calibration intervals.
Conduct borescope inspections, lube oil sampling, and visual checks immediately post-run to identify early signs of wear, thermal distress, foreign object damage (FOD), or fluid leaks and escalate findings to maintenance teams.
Execute standardized maintenance tasks and basic adjustments between runs—such as filter replacement, hose/tube fittings, and sensor reconnections—while following lockout/tagout and permit-to-work processes.
Maintain detailed run logs, engine health records, and test reports, uploading digital datasets to centralized repositories and annotating operational anomalies, maintenance actions, and environmental conditions.
Implement and document hot/hazardous work permits and ensure compliance with OSHA, local regulatory requirements, and company-specific safety management systems (SMS) during engine operations.
Support engine acceptance, teardown, and reassembly activities by providing operational context, tending to engine handling and mounting fixtures, and confirming torque sequences and alignment per OEM manuals.
Participate in root-cause investigations for engine events, providing first-hand operational observations, test-cell data, and photographic evidence to support engineering failure analysis or reliability studies.
Conduct fuel and oil system flushes, sample collection, and contamination checks following defined procedures and coordinate with lab services for fluid analysis when contamination is suspected.
Maintain readiness of ground support equipment—starting carts, fuel carts, bleed air systems, inerting systems—and ensure GSE is inspected, fueled, and positioned prior to engine runs.
Train and mentor junior operators and support staff on run procedures, safety expectations, emergency response, and proper use of test cell instrumentation and personal protective equipment (PPE).
Implement continuous improvement suggestions from test data and post-run reviews to optimize start-up sequences, reduce run-cycle time, and enhance safety margins while preserving test integrity.
Liaise with suppliers and OEM technical representatives to coordinate on-site engine diagnostics, warranty condition assessments, and parts replacements as required by run outcomes or maintenance findings.
Ensure test-cell and hangar housekeeping, proper storage of hazardous materials, and disposal of waste fluids in accordance with environmental regulations and hazardous materials handling procedures.
Facilitate communications with flight operations, dispatch, or maintenance control to schedule engine runs around operational windows, coordinate availability of required parts, and minimize aircraft downtime.

Secondary Functions

Support inventory tracking for engine spares, consumables, and test instruments; raise requisitions and help prioritize critical purchases for upcoming test programs.
Assist engineering teams in running baseline performance verification tests, emission checks, and endurance cycles used for certification or compliance demonstrations.
Participate in continuous training and competency assessments; maintain certifications for breathing apparatus, fire watch, and hazardous material handling.
Provide logistical support for logistics and transportation of engines to test cells, including rigging, cradle preparation, and coordinating with facilities and shipping teams.
Contribute to the development and refinement of run cards, SOPs, and emergency response plans based on operational experience and lessons learned from test events.
Support periodic checks of fire suppression and inerting systems; perform post-incident recovery inspections and help restore the test cell to operational status.
