## Description

The Development Test Engineer owns the planning, execution, and analysis of tests that turn designs into flight-ready hardware. This role sits at the center of engineering, manufacturing, and operations-translating requirements into real-world validation through benchtop, environmental, subsystem, and vehicle-level testing. You will design test hardware, write procedures, run tests, break things early, and close the loop back into design with clear data and recommendations.

This is a hands-on role for engineers who thrive in fast-paced, ambiguity-heavy environments and believe the fastest way to learn is to test real hardware.

Responsibilities

 * Own development and qualification testing for avionics, mechanisms, propulsion, structures, and integrated vehicle subsystems
 * Design and build test fixtures, ground support equipment (GSE), and instrumentation for benchtop, environmental, and system-level tests
 * Author test plans, procedures, and reports aligned with program requirements and qualification intent
 * Execute vibration, thermal, shock, EMI/EMC, functional, and performance testing
 * Instrument hardware and vehicles with sensors (strain, temp, pressure, accel, current/voltage) and DAQ systems
 * Lead anomaly detection, root-cause analysis, and corrective action closure
 * Partner closely with design engineering to feed test results back into rapid design iteration
 * Support integration operations, range testing, and flight test campaigns as needed
 * Maintain rigorous configuration control, data management, and test documentation
 * Improve test infrastructure, automation, and data quality to increase test cadence and learning velocity
