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.
