Alexandre Petitjean is a seasoned embedded and systems software engineer with 13 years’ experience building robust C/C++ solutions for navigation, medical devices, and IoT, now leading teams as C++ Applications Team Lead at SBG Systems and founding PTJ Pedals. He has a track record of designing modular, plugin-based architectures and bringing prototypes to production—from an examination middleware at Echosens to flight-validated pollution detection at LNE. Comfortable across the stack, he combines low-level embedded work (RTOS, BLE, Xenomai) with modern tooling (CMake, conan, Docker) and hands-on CI practices. Alexandre is also an active backend contributor to the popular Mopidy Python music server, adding integrations and improving core configuration—showing fluency beyond C++ into open-source ecosystems. He thrives in startup-like, transversal roles where research, product and engineering intersect, and often bridges hardware constraints with pragmatic software design.
