In this role, you will develop test plans, execute propulsion and fluid system tests, collect and analyze data, disposition anomalies, and verify that hardware meets all specifications. The position offers an excellent opportunity to contribute to cutting-edge spacecraft propulsion technologies in a fast-paced, mission-driven environment.

RESPONSIBILITIES

• Define and lead test strategies for propulsion and fluid system programs, including requirements verification, procedure development, and execution oversight.

• Author and review propulsion and fluids test documentation including plans, procedures, readiness reports, and compliance matrices.

• 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 3: $120,000-$160,000
• Senior Test Engineer: $140,000-$195,000

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.

ADDITIONAL REQUIREMENTS
