Required

Familiar with Git and Linux

Experienced with Unix Shell (Bash)

Capable of working in C/C++

Experienced with Embedded programming

Linux - development takes place primarily on computers with Linux distribution (Debian, Ubuntu, ...)

Rust - in the current project it is the primary language

Bash - this language is not our priority and most of the time we do not use it, but it is supported by the built-in Linux distribution so we expect some knowledge from you (grep, sed, awk, ...)

C - there will not be any future development in this language, but you should know it at least at the level of understanding the code

Gdb - knowledge of general principles and the ability to debug applications on a remote system using a gdb server

Git (GitLab, GitHub) - used for versioning and managing source code. You should be familiar with the Pull/Merge Request Policy and Code Review

Cross-compilations - general knowledge of translation issues for different architectures (ARM)

Embedded protocols - basic overview of communication protocols GPIO, I2C, SPI, USART, MIPI and their use in Linux at the application level. The advantage is an understanding of their functioning at the kernel level, where occasional intervention in their functioning is expected
