Environmental Test Engineer

We are looking for an Environmental Test Engineer to own the launch and space environmental qualification and acceptance test campaign for E-Space's large deployable antenna structure. This person will define, plan, and execute vibration, shock, thermal-vacuum, and acoustic testing for the stowed and deployed antenna assembly, from requirements flow-down through anomaly disposition and test report. This is a hands-on role for someone who treats a test anomaly as the most interesting part of the job.

On-site in California or Texas. Test facility coordination and hardware presence required. Some travel between sites expected.

What you will do:

• Own the environmental test plan for the integrated antenna structure - vibration, shock, acoustic, and TVAC - from requirements flow-down to test report.
• Define test levels and acceptance/qualification margins based on launch vehicle environments and system-level requirements, working with the structures analyst and IAS lead.
• Coordinate with test facilities (in-house and external) to plan, schedule, and execute test campaigns for the stowed antenna assembly.
• Instrument and fixture test articles; develop test procedures, pre-test predictions, and test-as-you-fly configurations.
• Perform real-time data monitoring during test execution; make go/no-go calls and manage test anomaly response in accordance with procedures.
• Own post-test inspection, data reduction, and correlation of test results against pre-test predictions.
• Document test results; maintain test verification closure records in the V&V matrix.

Required qualifications:

• BS or MS or Ph.D. in Aerospace or Mechanical Engineering, or equivalent.
• Experience planning and executing structural environmental test campaigns - vibration, shock, or thermal-vacuum - for flight or high-reliability hardware.
• Experience with fixturing, instrumentation (accelerometers, strain gauges, RTDs/PRTs), and data acquisition systems.
• Ability to develop pre-test predictions and interpret post-test data against FEA model outputs.
• Familiarity with MIL-STD-1540, GEVS, or equivalent environmental test standards.

Preferred qualifications:

• Experience with large or flexible structures - solar arrays, booms, deployable antennas, or membrane/gossamer systems - where conventional rigid-body fixturing assumptions break down.
• TVAC deployment testing experience, or equivalent thermal-vacuum test of mechanism or deployable hardware.
• Experience with model-test correlation and understanding of how fixturing and test-article mass affect frequency response.
• Familiarity with structural dynamics analysis tools (Nastran, ANSYS, or equivalent).

Additional Requirements

This is a fast-paced, high-impact environment - flexibility to occasionally work extended hours or weekends during critical periods is expected.
