Sphere Defense Tech Stack

Counter-UAS defense systems with autonomous countermeasures and jet propulsion

Defense and Space Manufacturing Brussels 2–10 employees Privately Held

Sphere Defense builds sovereign counter-drone systems for allied defense. The tech stack—C/C++, Rust, PX4, ROS 2, Gazebo, NVIDIA, Qualcomm—reflects an embedded-systems-focused engineering org running physics simulations (STAR-CCM+, Ansys, Simulink) and avionics design (Altium, Cadence). Active work spans autonomous countermeasures, jet engine design for small UAS, and CI/CD pipeline setup, with hiring concentrated in senior engineering roles across Belgium and Canada—a pattern typical of early-stage hardware-software teams scaling from prototype to production.

About Sphere Defense

Sphere Defense develops counter-UAS (counter-unmanned aircraft) systems for government and allied defense customers. Based in Brussels, the company operates as a small engineering team focused on autonomous countermeasures, unmanned aircraft design, and propulsion systems for small-scale platforms. Current priorities include transitioning prototypes into production via external manufacturing partners, scaling mid-volume output, and expanding lab capacity. The product combines embedded software (sensing, actuation), physics-based simulation, and avionics hardware design.
