Mechanical Engineering System

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. 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.
As a Mechanical Engineer at Elroy Air, you will be responsible for owning the design, analysis, build, and test of the flight-critical mechanical systems that bring our autonomous cargo UAV to life. You will work on a range of mechanical and structural systems, driving mechanical design and decision making that enables aircraft testing and flight.
Designing and developing vehicle subsystems, including primary and secondary structures, flight control surfaces and actuation systems, landing gear, and thermal management systems from architecture definition through integration
Apply first-principles analysis, FEA, trade studies, and engineering best practices to ensure components and assemblies meet load, weight, and safety requirements for flight
Define subsystem and component requirements compatible with safety, performance, and program objectives; Select materials appropriate for aerospace applications (aluminum alloys, titanium, composites) with consideration for weight, strength, fatigue, and manufacturability
Apply DFM principles across fabrication methods including composites, sheet metal, machining, 3D printing, welding, and bonding to support efficient, producible designs
Conduct environmental analysis and testing, including vibration, shock, thermal, and corrosion, and support design and build of test fixtures to verify subsystem performance and safety
