### Nice to Haves:

-   Hailo SDK and/or AMD ROCm compilation (iX10)
-   Writing custom kernels / operator plugins
-   Remote sensing / large-image handling 
-   RF / IQ signal data exposure
-   Meson build, Yocto / minimal Debian images
-   Model-weight protection / secure execution

**Who We Are**

  

Loft: Space Made Simple. 

  

Founded in 2017, Loft provides governments, companies, and research institutions with a fast, reliable, and simple way to deploy missions in orbit.

  

We integrate, launch, and operate spacecraft, offering end-to-end missions as a service across Earth observation, IoT connectivity, on-orbit AI, national security missions, and more. Leveraging our existing space infrastructure and an extensive inventory of satellite buses, Loft is reducing years-long integration and launch timelines to months. With more than 30 missions flown, Loft’s flight heritage and proven technologies enable customers to focus on their mission objectives.

  

With a growing fleet on track to reach 30 satellites by 2027, we are scaling up quickly across our offices in San Francisco, CA | Golden, CO | and Toulouse, France to meet accelerating demand for space infrastructure.
