Mostavio is building the future of advanced air mobility through the secure, all-electric, and autonomous development of manned and unmanned aerial vehicles (UAVs and eVTOLs). Our mission is to transform aviation by solving high-impact problems with innovative engineering and bold ideas.

Electronic & Firmware Engineer to join our multidisciplinary team and contribute to the development of the avionics, embedded systems, and safety-critical electronics that power our next-generation aircraft.

If you are passionate about embedded systems, autonomous aviation, and building reliable electronics for mission-critical environments, this is your opportunity to shape the future of flight.

Electronic & Firmware Engineer at Mostavio, you will play a pivotal role in designing, developing, and validating the electronic and embedded systems that support flight control, power management, sensing, and vehicle autonomy.

You will collaborate closely with mechanical, propulsion, and software teams to deliver robust, certifiable, aerospace-grade hardware and firmware.

Hardware Electronic Design Lead the design and development of avionics hardware, power electronics, sensor interfaces, and control boards using STM32 or similar ARM Cortex-M MCUs.

Develop schematics and multi-layer PCB layouts for flight-critical electronics.

Select components, evaluate tradeoffs, and ensure compliance with aerospace robustness, EMI/EMC, and environmental standards.

Firmware & Embedded Software Architect, develop,



and optimize embedded firmware for microcontrollers using C/C++ (bare-metal and/or RTOS).

Implement drivers, communication protocols (CAN, UART, I2C, SPI), sensor fusion interfaces, and safety-critical control logic.

Perform hardware-in-the-loop (HIL) testing, unit testing, and debugging using oscilloscopes, logic analyzers, JTAG/SWD, and other tools.

Collaborate with flight control, battery systems, and propulsion teams to ensure seamless hardware–software integration.

Produce detailed documentation, including electrical schematics, firmware architecture, ICDs, and test procedures.

Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Mechatronics, Electronic or equivalent.

3+ years of experience in embedded firmware development and electronic hardware design (aerospace, robotics, automotive, or other safety-critical sectors preferred).

Expert-level experience with STM32 microcontrollers, HAL/LL drivers, RTOS frameworks (FreeRTOS or similar), and low-level embedded C/C++.

Power electronics and DC power distribution

Communication buses: Familiarity with EMI/EMC considerations, grounding strategies, and environmental testing.

Bonus Skills Experience with flight-control systems, UAV avionics, or eVTOL architectures.

Experience with hardware-accelerated control loops, motor controllers, ESCs, or powertrain electronics.

As an early member in a fast-growing company, you’ll have the chance to grow with us and help define the future of autonomous aviation.
