Senior Embedded Firmware Engineer

Senior Embedded / Firmware Engineer (RTOS, communication, critical systems, secure embedded systems) Scope of responsibilities This is not a typical embedded role. It involves system design, deterministic communication, real-time operation, and ownership of key product components. You will work from low-level firmware up to backend communication. In practice, this means: Developing firmware for safety components and communication modules Designing and improving communication between two MCUs Working with real-time logic, state machines, and error handling Creating and maintaining hardware drivers (UART, SPI, I2C, GPIO) Designing and developing wireless communication systems (BLE onboarding, provisioning, data exchange) Ensuring stable backend communication via OCPP over WebSocket (or similar device-cloud protocols) Working on OTA and system resilience in a production environment (rollback, recovery, update security) Low-level debugging using professional tools (JTAG, SWD, logic analyzers, etc.) Designing APIs and communication layers between system modules Technology and architecture The system consists of two main units: Safety / Power Controller: nRF5340 or similar low-power class MCU (RTOS / embedded firmware) Communication / Application Controller: i.MX RT1061 or similar application-grade MCU (RTOS / embedded Linux optional) MCUs communicate via a proprietary protocol designed for
