What you will do

• Design robust firmware architecture for MCUs using bare-metal and RTOS environments (FreeRTOS, Zephyr).
• Develop low-level drivers for peripherals, sensors, RF modules, and power-management ICs.
• Implement deterministic real-time control loops and manage interrupts, timing, and scheduling.
• Conduct board bring-up and system debugging using oscilloscopes, logic analyzers, and JTAG/SWD.
• Own the prototype-to-production maturity path, including HITL testing and automated test benches.
• Build secure bootloaders and reliable over-the-air (OTA) firmware update mechanisms.

Requirements

• Master’s degree in Electrical/Computer Engineering, Embedded Systems, Computer Science, or equivalent.
• 2 to 10+ years of experience in embedded software development.
• Proven experience taking at least one complete embedded product from initial prototype to mass production.
• Proficiency in Embedded C/C++ with experience on ARM Cortex-M MCUs.
• Deep understanding of communication buses: SPI, I2C, UART, USB, and CAN.
• Strong discipline in version control, CI/CD pipelines, and automated firmware test methodologies.

Nice to have

• Experience developing drone, UAV, remote control, or radio communication firmware.
• Experience designing RF link or wireless protocol firmware.
• Background working with ruggedized, military, or industrial-grade systems.
• Professional familiarity with Rust.
