Unmanned aircraft systems for logistics and defense applications
Poseidon Aerospace is a 2–10-person hardware startup building unmanned aircraft for logistics missions. The tech stack—dominated by mechanical CAD (SolidWorks, CATIA, NX), computational fluid dynamics (ANSYS, STAR-CCM+, OpenFOAM), and flight simulation (X-Plane, ROS)—reflects a pure aerospace engineering operation. Hiring is heavily weighted toward engineering (27 of 38 open roles), with notable gaps in proposal development and manufacturing scaling, suggesting they're transitioning from prototype validation toward production and pursuing government contracts.

Poseidon Aerospace designs and develops unmanned aircraft systems targeting logistics and defense segments. Based in San Francisco, the company operates as a lean engineering organization focused on aerodynamic validation, flight dynamics modeling, and prototype-to-production transition. Active projects span composite aircraft testing, flight planning with collision avoidance, digital manufacturing integration, and compliance documentation—typical of a defense-focused aerospace vendor pursuing government funding. Key operational friction points include winning new defense programs, managing funding windows, and scaling manufacturing while maintaining quality and compliance.
SolidWorks, CATIA, NX for mechanical design; ANSYS, STAR-CCM+, OpenFOAM for aerodynamics; X-Plane and ROS for flight simulation; MATLAB/Simulink for modeling.
