About Prometheus Energetics

Prometheus Energetics is an independent U.S.

-based merchant supplier of solid rocket motors and warheads. A joint venture between Kratos Defense & Security Solutions and Rafael Advanced Defense Systems, Prometheus combines U.S. industrial speed and credibility with decades of combat-proven designs, manufacturing know-how, and technical training to deliver field-ready products at scale.

Prometheus Energetics is seeking an experienced Test Engineer / Senior Test Engineer to serve as a primary technical authority for solid rocket motor test operations, owning the design, integration, commission, and lifecycle support of propulsion and energetic test infrastructure. Reporting directly to the Director of Engineering, this role establishes an independent, high-rigor test engineering capability as Prometheus Energetics transitions from facility startup into high-rate production.

The role encompasses the full spectrum of SRM test execution from development and R&D static fires through formal qualification, production acceptance, and flight test support. The ideal candidate brings 4 to 10 years of hands-on propulsion test stand operations, data acquisition architecture, hazard containment, and test-like-you-fly (TLYF) execution experience, ensuring the highest standards of safety, data fidelity, and mission success.

• Design, develop, commission, and sustain scalable propulsion test stands and ground support equipment (GSE) supporting subscale, development, qualification, and production acceptance static firings.
• Design and integrate high-press? oh I made a mistake; we need high-pressure derivative but with hyphen: high-pressure pneumatic, hydraulic, and fluid delivery systems for remotely operated test stand configurations.
• Architect industrial electrical and control systems for test cell operations, including low-voltage power distribution, grounding/bonding, safety interlocks, PLC automation (e.g., Siemens/Allen-Bradley), and abort logic.
• Select, integrate, and maintain high-speed data acquisition (DAQ) hardware (kHz to MHz sampling rates) and sensor suites, including load cells, high-frequency pressure transducers, thermocouples, accelerometers, strain gauges, and radiometers.
• Develop and maintain automated test control sequences, DAQ configurations, and data processing tools using LabVIEW, Python, MATLAB, or PLC-based control logic.

• Lead the development of comprehensive test plans, standard operating procedures (SOPs), hazard analyses, pre-fire checklists, and countdown sequences for motor static firings and environmental screening (vibration, thermal, shock).
• Serve as Test Conductor or Lead Test Engineer during energetic operations, directing console operators, managing countdowns, and enforcing range and safety perimeters.
• Execute static fire campaigns, real-time telemetry monitoring, and immediate post-test safing, ensuring safe containment of toxic combustion products and high-pressure hardware.
• Champion Test-Like-You-Fly (TLYF) practices, ensuring ground test environments, line losses, and instrumentation configurations accurately reflect flight operational profiles.
• Support production acceptance testing (PAT) and scale test operations to support rapid motor production throughput.

• Process, filter, and analyze raw test data to deliver rapid post-fire summary packages, evaluating pressure-time traces, thrust curves, total impulse, ignition delay, and thermal/vibration environments.
• Correlate measured test data against predicted ballistic, thermal, and structural analytical models in collaboration with ballisticians and structural analysts.
• Lead root-cause investigations and failure review boards (FRACAS/MRB) for test cell anomalies, facility hardware failures, DAQ dropouts, or unpredicted motor performance behavior.
• Maintain rigorous test stand documentation, including sensor calibration logs, channel lists, facility P&IDs, electrical schematics, and test execution history.

• Partner closely with Propulsion, Manufacturing, Quality, Ballistics, and EHS teams to ensure hardware test-readiness and design-for-testability (DFT).
• Strictly enforce explosive safety regulations, including DoD 4145.26-M, range safety requirements, ordnance handling protocols, and pressure vessel safety standards.
• Participate in formal design reviews (PDR, CDR, TRR) to provide test perspective, instrumentation access plans, and verification evidence.
• Mentor junior test engineers and technicians, fostering a culture of operational discipline, safety, and technical excellence.

• Bachelor's degree in Aerospace Engineering, Mechanical Engineering, Chemical Engineering, or a related engineering discipline from an accredited university. (Associate's degree with 5+ years of relevant SRM experience may…
