The Test Engineer at Elroy Air will play a crucial role in the development, validation, and certification of Chaparral, our autonomous VTOL cargo aircraft. In this role, you will bridge the gap between design and reality by planning, setting up, and executing rigorous tests on components, sub-systems, and integrated aircraft systems. Whether working on mechanical fixtures, electrical test benches, or environmental chambers, you will ensure our hardware meets performance, reliability, and safety standards. This role requires an adaptable engineer from an electrical, mechanical, or aerospace background who thrives in a hands-on environment and is eager to advance the future of middle-mile logistics.

Responsibilities

Test Planning & Execution: Develop detailed test plans, procedures, and safety hazard analyses for structural, mechanical, environmental, and electrical components.

Rig & Fixture Design: Design, build, and commission custom test fixtures, automated test equipment, and ground-support equipment using CAD and rapid-prototyping methods.

Instrumentation & Data Acquisition: Select, install, and calibrate sensors such as strain gauges, thermocouples, accelerometers, and pressure transducers. Configure data acquisition (DAQ) systems to capture critical test data.

Data Analysis & Diagnostic Troubleshooting: Process raw test data to evaluate system performance against design requirements. Investigate, diagnose, and document root-cause failures when components do not perform as expected.

Cross-Functional Collaboration: Partner closely with Design, Systems, and Flight Test engineering teams to translate high-level aircraft requirements into verifiable, concrete physical test criteria.

Safety & Regulatory Compliance: Maintain a safe testing environment by adhering to strict laboratory and field safety protocols, ensuring all documentation supports our FAA and UAS certification pathways.

Our Ideal Candidate

Bachelor’s degree in Electrical Engineering, Aerospace Engineering, Mechanical Engineering, or a related technical discipline.

2+ years of professional experience in a dedicated engineering test environment (e.g., hardware verification, environmental qualification, or physical lab testing).

Hands-on experience with electric motors, propulsion systems, battery systems, EV systems

Hands-on experience setting up and operating data acquisition hardware (e.g., National Instruments, Dewesoft) and associated instrumentation.

Strong mechanical or electrical troubleshooting skills—comfortable parsing engineering schematics, 3D CAD models, or wiring diagrams to diagnose issues.
