Open Cosmos designs, builds and operates small satellites, and its stack shows two engineering fronts. Geospatial Python (GDAL, Rasterio, xarray) supports image processing, while SRv6, IS-IS, SONiC and FRRouting point to a next-generation satcom network built around changing LEO topologies. Hiring is accelerating and engineering-heavy, with roles open across Spain, Greece, Portugal and Canada.
