About Odys Our mission at Odys is simple - we build safe, sustainable aircraft to cut travel time in half on the world's busiest corridors. Our flagship aircraft Alta enables travelers to skip the big-airport hassle by using city helipads and local airports to connect cities less than 1,000 miles apart (approx 40% of flights). And on average cut CO2 by 76% on tens of billions of flight miles globally. To get there, we start with our UAV called Laila for commercial logistics, medical transport, humanitarian aid, disaster relief, and defense missions. We're deploying aircraft with launch partners (Fiji Airways, Honeywell, Aramex, US Navy) beginning in late 2025 and already have firm orders for aircraft under contract. We're a team of expert engineers from deep tech and aerospace that focus on fast iterations loops (completed transition flight faster than our peers) combined with mastery of the aircraft certification process. Previously, our team developed custom drones, brought...

About the Role At H3X, we are building the most advanced electric motors in the world for sustainable aviation, marine, industrial, and defense applications. At 12 kW/kg continuous, the HPDM family of integrated motor drives is a step change in electric propulsion technology and removes one of the main barriers blocking widespread proliferation of electric and hybrid aircraft. Our motors range in size from 30 kW to 30 MW, include integrated drives, and are 3X lighter than competitors' systems. H3X is looking to hire a test engineering intern this summer to support R&D and production testing across the HPDM product line. This is not an ordinary internship- you will be given the full responsibility of a test engineer. The engineering team is intentionally small and operates at a very fast pace. A high degree of self-motivation and responsibility is required as you will be given significant freedom and will be directly responsible for your parts. Responsibilities...
