Embedded Systems

Bridging the gap between silicon and software, the Embedded Systems team designs the low-level tools that make NanoXplore’s FPGAs truly usable and powerful. 


Their core mission : developing the main SDK (Software Development Kit), firmware, and all embedded components that enable seamless configuration, control, and integration of our devices. From bootloaders and drivers to board support packages and diagnostic tools, they ensure our chips speak the right language whether on a satellite, in a defense system, or in a test environment. Their work is foundational : without it, nothing runs. 


What sets them apart is their ability to think system-wide. They work closely with hardware teams and application engineers, adapt to evolving specs, and support real-world use cases with reliability and reactivity. 

They’re not just writing code : they’re building the ecosystem around our FPGAs.


Driven by curiosity and precision, it’s a team where autonomy meets collaboration, and where each line of code contributes to something bigger : making advanced microelectronics accessible and operational for the most demanding applications.
