Test Engineer

At Elroy Air, we build autonomous vertical takeoff and landing (VTOL) cargo drones to change the way the world moves goods. Transporting cargo by air is faster and more direct than by land or sea, but it has been prohibitively expensive for medium-size loads. We've set out to expand middle-mile logistics possibilities across multiple sectors, with our sights on a $420Bn global total addressable market for cargo logistics across defense, commercial and rapid response.   We are a team of builders, engineers, and operators who believe that the defense, commercial, and rapid response communities need faster, better logistics solutions. We are seeing increasing demand as customers and prospects respond enthusiastically to the systems we’ve built. As we mature and deploy our offerings, we are looking for people like you: motivated collaborators, enthusiastic about our mission and ready to roll up their sleeves and make a big impact to improve how logistics works around the world. You will play an important role in establishing the Elroy Air Chaparral as the industry standard in this massive market.   We believe diverse perspectives at all levels of the organization are critical to innovation and employee development. This includes but is not limited to gender identity, race, ethnicity, sexual orientation, gender expression, religion, age, ability, parenthood status, veteran status, educational background, citizenship status, or any combination of these characteristics. 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
