# Embedded Firmware Engineer

Who we are At Praxa Sense, we are redefining non-invasive health monitoring with our optical innovation ALIS® – a speckle-based biosensor enabling new frontiers in remote vital sign tracking. We’re looking for an Embedded Firmware Engineer – Precision Biosensing Platform who thrives at the intersection of hardware and code: crafting the logic that turns precision optics and electronics into accurate, reliable data streams. You’ll design and implement embedded systems software for our ARM-based sensing platform, ensuring that every photon and every signal is handled efficiently and intelligently. Your firmware will be the heartbeat of ALIS®, which means determining how the sensor measures, synchronizes, filters, and communicates. What you will do Develop and maintain embedded firmware in C++ for ARM32-based microcontrollers. Design and implement modular drivers, data acquisition routines, and real-time control loops. Integrate and optimize communication protocols (e.g. UART, SPI, BLE, USB) for robust data exchange. Collaborate closely with signal processing and data science engineers to align timing, synchronization, and calibration logic. Implement unit and integratio
