• Analyze complex propulsion and fluid system test data, resolve anomalies, and lead root cause investigations and corrective actions. 

• Oversee test campaigns spanning propulsion and fluids disciplines including proof testing, leak testing, functional/performance testing, and propellant loading operations, ensuring full traceability to system requirements. 

• Design, build, commission, and operate propulsion and fluids ground support equipment in support of testing operations. 

• Interface with program leadership, customers, and regulatory bodies during design reviews and formal propulsion test events. 

• Ensure compliance with industry, range safety, and military standards for propulsion and hazardous fluid test planning and reporting. 

QUALIFICATIONS 

• Bachelor's degree in aerospace, mechanical, chemical engineering, or related technical discipline. 

• Years of relevant experience in propulsion or fluid systems test engineering for aerospace, defense, or high-reliability systems in line with engineering level. 

• Knowledge of propulsion and fluid system test methodologies including proof, leak, functional, and performance testing. 

• Experience performing propulsion or fluid system test campaigns and coordinating multidisciplinary teams. 

• Strong background in data analysis, systems engineering, and failure analysis for propulsion hardware. 

• Excellent communication, leadership, and technical documentation skills. 

• U.S. Citizenship required due to government contracts.  

PREFERRED SKILLS AND EXPERIENCE 

• Master's or higher degree in aerospace, mechanical, or chemical engineering. 

• Expertise with data acquisition, test automation, and scripting (LabVIEW, Python, MATLAB) for propulsion test environments. 

• Hands-on experience with propulsion components including thrusters, valves, regulators, tanks, and feed systems. 

• Familiarity with propellant handling, hazardous fluid operations, and range safety requirements. 

• Experience with test standards such as MIL-STD-810, AIAA propulsion standards, or NASA/DoD propulsion test specs. 

• Experience working in classified or secure test environments. 

• Active Secret or Top Secret clearance. 

COMPENSATION AND BENEFITS 

Base Salary: 

• Test Engineer 2:  $100,000-$120,000
• Test Engineer 3: $125,000-$155,000
• Senior Test Engineer: $140,000-$175,000

Equity + Benefits including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave 

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, location, and experience.
