Senior Firmware Engineer

Company Description

Mostavio is building the future of advanced air mobility through the safe, 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.

We are seeking a Firmware Engineer to join our multidisciplinary team and contribute to the development of safety-critical embedded software and avionics firmware that power our next-generation aircraft.

This role is ideal for engineers passionate about embedded systems, real-time firmware, and electronics.

Key Responsibilities

As a Firmware Engineer at Mostavio, you will be responsible for the architecture, development, testing, and validation of embedded firmware running on flight-critical avionics systems. You will work closely with electronics and hardware engineer, flight control, propulsion, and autonomy teams to ensure robust hardware–software sensor monitoring and integration across the aircraft.

Your work will directly impact flight control, power management, sensing, redundancy, and vehicle safety.

• Architect, develop, and maintain embedded firmware for ARM Cortex-M microcontrollers (NXP, STM32 or similar) using C/C++.
• Develop bare-metal and RTOS-based (FreeRTOS / AzureRTOS or similar) firmware architectures for safety-critical systems.
• Implement and optimize:
• Low-level drivers
• Board support packages (BSPs)
• Real-time task scheduling
• Interrupt handling and DMA
• Design and implement fault-tolerant and redundant firmware architectures aligned with aviation safety requirements.
• Implement and maintain embedded communication stacks and protocols, including:
• CAN / CANopen / UAVCAN
• UART
• SPI
• I2C
• RS485
• Ethernet (where applicable)
• Develop robust inter-module communication and health-monitoring mechanisms for avionics subsystems.
• Support sensor interfaces, data acquisition, and filtering pipelines for flight-critical inputs.
• Collaborate closely with electronics, propulsion, battery, and flight-control teams to ensure seamless firmware–hardware integration.
• Perform hardware-in-the-loop (HIL) testing, unit testing, and system-level validation.
• Debug and validate firmware using professional tools:
• JTAG / SWD
• Oscilloscopes
• Logic analyzers
• Protocol analyzers
• Support testing under real-world operating conditions including vibration, EMI, thermal stress, and high-power environments.
• Produce high-quality technical documentation, including:
• Firmware architecture documentation
• Interface Control Documents (ICDs)
• Test plans and test reports
• Coding standards and design notes
• Support certification-related documentation efforts.
• Ensure firmware development aligns with aerospace processes and best practices (DO-178C familiarity preferred).

Qualifications

• Bachelor's or Master's degree in Electronics Engineering, Electrical Engineering, Computer Engineering, Mechatronics, or equivalent.
• 3+ years of experience in embedded firmware development (aerospace, robotics, automotive, or other safety-critical industries preferred).
• Expert-level experience with:
• STM32 microcontrollers / NXP Mcu
• HAL / LL drivers
• FreeRTOS , AzureRTOS or similar RTOS
• Low-level embedded C/C++
• Strong understanding of:
• Real-time systems
• Interrupt-driven firmware
• Embedded memory management
• Power-aware firmware design
• Proven experience working with embedded communication buses:
• CAN
• UART
• SPI
• I2C
• RS485
• Ethernet
• Hands-on experience debugging embedded systems using oscilloscopes, logic analyzers, JTAG/SWD, and protocol analyzers.
• Excellent problem-solving skills, strong documentation habits, and ability to operate in a fast-paced, multidisciplinary environment.

Bonus Skills

• Experience with UAV avionics, flight-control systems, or eVTOL platforms.
• Familiarity with aerospace certification frameworks:
• DO-178C
• DO-254
• ARP4754A
• ARP4761
• Experience with UAVCAN, CANopen, or custom safety-critical communication stacks.
• Knowledge of battery systems, BMS integration, and power-aware embedded firmware.
• Experience with motor controllers, ESCs, or hardware-accelerated control loops.
