Environmental Test EngineerThe Environmental Test Engineer (Vibration and TVAC) is responsible for planning, executing, and documenting mechanical and thermal-vacuum tests to verify the environmental durability of spacecraft components, subsystems, and full systems. This engineer ensures test campaigns meet customer and program requirements for qualification and acceptance.Key responsibilities include developing and executing test plans and procedures for vibration (sine, random, shock) and thermal vacuum (TVAC) testing, setting up, calibrating, and operating test equipment including shakers, thermal chambers, vacuum chambers, and data acquisition systems, collaborating with design, manufacturing, and systems engineering teams to define environmental test requirements, performing real-time test monitoring and troubleshooting to ensure successful completion of test campaigns, ensuring all testing complies with relevant standards, coordinating with technicians to configure test setups, instrumentation, and test article fixturing, leading or supporting root cause investigations for test anomalies or failures, generating detailed test reports including data analysis, plots, and pass/fail criteria, maintaining equipment and ensuring test facilities meet operational readiness, and participating in continuous improvement activities to enhance test efficiency, safety, and reliability.Required qualifications include a bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related field, 3+ years of experience in environmental testing, preferably in aerospace or defense, hands-on experience with electrodynamic shakers, TVAC chambers, accelerometers, thermal sensors, and DAQ systems, strong knowledge of vibration and thermal environments relevant to spaceflight hardware, familiarity with instrumentation setup, calibration, and data analysis, ability to work in cleanroom environments and follow contamination control procedures, excellent written and verbal communication skills, and strong analytical and problem-solving abilities.Preferred qualifications include experience with software such as LabVIEW, TestStand, MATLAB, or Python for test automation and data analysis, experience supporting launch vehicle or satellite environmental qualification campaigns, knowledge of industry standards: MIL-STD-810, MIL-STD-1540, ECSS-E-ST-10-03C, etc., and familiarity with thermal modeling and simulation tools.Working conditions may involve shift work and extended hours during test campaigns, physical requirements may include lifting up to 50 lbs and working in confined or high-vacuum areas, and must be able to work in a fast-paced and collaborative environment with strict deadlines.
