Responsibilities

• Design, develop, and maintain embedded software and firmware for aerospace systems.
• Implement solutions across bare-metal / RTOS-based systems and Embedded Linux environments.
• Develop and optimize C/C++ code for microcontrollers and embedded processors.
• Integrate software with hardware components, including sensors, communication modules, and peripherals.
• Develop and maintain drivers and interfaces (UART, SPI, I2C, CAN, etc.).
• Perform debugging, testing, and validation at both system and component level.
• Contribute to system and network architecture and software design decisions.
• Ensure code quality, maintainability, and proper documentation.
• Collaborate in version control workflows, CI/CD, and testing processes.

Qualifications

• Bachelor’s degree in computer engineering, software engineering, telecommunications, related field or equivalent experience.
• ~3–5 years of experience in embedded software and/or firmware development.
• Strong proficiency in C/C++.
• Solid experience with RTOS (e.g., FreeRTOS, Zephyr or similar).
