Job description
About Poseidon Aerospace:
Poseidon Aerospace is reimagining how the world moves goods. We build and operate full-size autonomous cargo aircraft; Heron, a seaplane, and Egret, a STOL aircraft; each capable of carrying two tons of payload over a thousand nautical miles. From remote communities to contested logistics operations, our platforms unlock a new cost curve for air freight, making it faster, cheaper, and accessible anywhere it's needed. Headquartered in the San Francisco Bay Area with locations in Washington DC, Oregon, and Maine; we're building something consequential.
As an Aerospace Engineer at Poseidon Aerospace, you will shape the aerodynamic and performance characteristics of our next-generation composite aircraft. Your work will include CFD modeling, aerodynamic optimization, performance analysis, and test correlation. You will help translate flight objectives such as speed, range, and efficiency into manufacturable aircraft. The role combines analytical work with hands-on testing and collaboration across design and manufacturing teams.
Responsibilities:
Ideal Qualifications:
Nice to Have:
What you get from us
Even if you don't meet every qualification listed, we encourage you to apply. At Poseidon Aerospace, we value diverse perspectives and are always looking for talented individuals with unconventional backgrounds.
