Embedded Firmware Engineer
Dronus, a leading company in autonomous drone technology, is seeking a highly skilled Embedded Firmware Engineer to join our innovative team in Trieste. We are looking for a professional with proven expertise in microcontroller firmware development and embedded Linux systems, passionate about advancing real-time embedded solutions for aerial automation. This role offers the chance to contribute directly to the core software that powers our next-generation drone platforms, ensuring robust, efficient, and scalable performance in dynamic environments.
Key Responsibilities

Design, develop, and debug firmware for STM32 microcontrollers using FreeRTOS, including real-time task management, interrupt handling, and peripheral drivers (e.g., UART, SPI, I2C, CAN).
Implement and optimize embedded Linux systems on processors, focusing on kernel customization, device tree configurations, and Yocto-based builds for drone-specific applications.
Integrate sensors and communication protocols (e.g., GPS, IMU, LiDAR interfaces) into firmware stacks, ensuring seamless hardware‑software interaction and compliance with safety‑critical standards like IEC 62304 where applicable.
Conduct unit testing, integration testing, and validation of firmware using tools such as oscilloscopes, logic analyzers, and automated test frameworks; perform debugging and optimization for low‑power and high‑reliability operation.
Collaborate with hardware design, software architecture, and quality assurance teams to support prototype bring‑up, system integration, and continuous improvement initiatives.
Contribute to over‑the‑air (OTA) update mechanisms, bootloader development, and version control using Git in an agile development environment.
Document firmware designs, APIs, and test procedures to facilitate maintainability and knowledge transfer.

Qualifications

Bachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, or a related field.
At least 4 years of hands‑on experience in embedded firmware development, with a strong focus on C/C++ for resource‑constrained systems.
Proficiency in FreeRTOS or similar RTOS for STM32 microcontrollers, including multi‑threaded programming, IPC, and POSIX APIs.
Solid experience with embedded Linux, including kernel modules, drivers, and build systems (e.g., Yocto or Buildroot).
Familiarity with debugging tools (e.g., JTAG/SWD debuggers, GDB) and version control systems (e.g., Git).
Knowledge of communication protocols (e.g., I2C, SPI, USB, Ethernet) and sensor integration in embedded environments.

Preferred Qualifications

Experience with drone or robotics applications, such as real‑time control loops, sensor fusion, or autonomous navigation firmware.
Proficiency in Python for scripting and automation in embedded testing pipelines.
Background in safety‑critical systems development (e.g., MISRA C compliance, unit testing with frameworks like Unity or Ceedling).
Exposure to ARM Cortex‑M architectures beyond STM32 (e.g., NXP, TI) and bare‑metal programming.
Familiarity with agile methodologies and CI/CD pipelines for embedded software (e.g., Jenkins, GitLab CI).
