Spire operates a deployed satellite constellation collecting real-time Earth data via RF technology. The stack reveals a hardware-forward company: heavy C++, VHDL, and embedded systems (ARM, Xilinx, LabVIEW, MATLAB, PetaLinux) sit alongside backend infrastructure (AWS, PostgreSQL, Databricks). The active project list—geolocation algorithm refinement, observability for satellite ops, legacy Python-to-Rust migration, flight-actuator qualification—shows Spire is simultaneously hardening signal-processing pipelines while modernizing ground infrastructure. Engineering dominance in hiring (30 of 55 open roles) and a notable "Space Reconnaissance Director" opening reflect the operational complexity of managing a constellation at scale.
