Software Engineer UAV/UGV

We are Barragier — a multidisciplinary team developing intelligent control and AI systems for drones, ground robots, and automated turrets.
We are looking for an experienced C/C++ Engineer to join our project focused on firmware development for stepper motor controllers (STM32) and a computer-vision-based targeting system running on Raspberry Pi.

Key Responsibilities:

• Develop firmware for precise and fast stepper motor control (turret, pan-tilt, stabilization);
• Implement motion algorithms, microstepping, acceleration/braking curves, and PID control;
• Optimize code for STM32 (using STM32CubeIDE / HAL / LL / FreeRTOS);
• Work with stepper motor drivers such as A4988, TMC2209, or similar;
• Implement communication interfaces between STM32 and Raspberry Pi (UART, I2C, SPI, GPIO);
• Integrate the firmware with the target tracking and aiming system (C++ / OpenCV) running on Raspberry Pi;
• Optimize performance, synchronize with video streams, and minimize control latency;
• Test and debug on real hardware setups.

Required Qualifications:

• Strong experience in C / C++ (C++11/14/17) — 2+ years;
• Hands-on experience with STM32 microcontrollers (HAL, LL, or bare-metal programming);
• Solid understanding of stepper motor control principles — drivers, timing, microstepping, feedback;
• Experience with UART, I2C, SPI, GPIO interfaces;
• Practical experience with Linux environments (Raspberry Pi OS / Ubuntu);
• Basic OpenCV or video-processing knowledge;
• Understanding of real-time systems, timers, interrupts, and DMA;
• Ability to read circuit diagrams and use oscilloscopes.

Nice to have:

• Integration with AI-based target detection or tracking modules;
• Python scripting for tooling or utilities;
• Familiarity with MAVLink / ROS protocols;
• ARM-level optimization and debugging skills.
