Mechanical Engineer - Propulsion

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 multiple automotive platforms into production, and electrified transportation vehicles that magnetically levitate, that roll, that fly. Together, we’ve been learning, developing, building, testing, and preparing for this challenge our entire lives.

Odys Aviation is pioneering next-generation hybrid-electric aircraft to make sustainable high-speed regional travel a reality. This role focuses on the mechanical packaging, thermal management, and manufacturability of high-speed generators, propulsion motors, power inverters, battery enclosures, and hybrid-electric powertrain systems - for our UAV (Laila) and eVTOL (Alta) programs. You will play a key role in integrating these components into Odys' next-generation aircraft, ensuring high efficiency, durability, and compliance with aerospace standards.

In this hands-on position, you will collaborate with electrical engineers, aircraft structural design experts, and certification teams to ensure your mechanical solutions conform to aerospace standards and best practices. The ideal candidate will thrive in fast-paced development cycles, be comfortable with quick design iterations, and have a strong ability to adapt to evolving system requirements. This is a hands-on role with full design cycle ownership, from conceptualization to hardware validation, contributing directly to Odys’s rapid path to flight testing and production aircraft roll-out.
