Senior🎓
Top SchoolRui Sousa is a Senior Principal Software Engineer with 26 years of experience specializing in embedded ARM Linux and networking, currently driving low-level platform features at NXP Semiconductors from the Greater Nice area. His career includes principal engineering roles at Freescale and Mindspeed and early open-source leadership on the OSS Sound Blaster Live! driver that shipped with Linux 2.2/2.4 kernels. Rui contributes to high-impact SDK work such as MCUXpresso, where he has implemented timer APIs, MMU and interrupt fixes, enet driver repairs for multiple i.MX8 devices, and hypervisor call abstractions. He blends deep hardware-facing C expertise with systems-level design, routinely touching boot, interrupt, and memory subsystems across SoC platforms. Trained in physics and engineering physics, he brings a methodical, measurement-driven approach to debugging and performance tuning that often uncovers subtle platform-level bugs before they reach customers. Colleagues rely on him for pragmatic, durable solutions that bridge silicon quirks and production firmware.
