Responsibilities

• Design and management of Linux embedded systems (Yocto, Buildroot).
• Linux kernel customization and driver development.
• Integration and management of drivers for external modules (LTE/5G modems, Bluetooth, Wi-Fi, GNSS).
• Interfacing with buses (I2C, SPI, UART, CAN).
• Full management of the Linux stack: kernel mode, user space, networking, security.
• System hardening and implementation of secure protocols (SSL/TLS).
• Process automation and scripting in bash and Python.
• Configuration of TCP/IP stack, routing, firewall (iptables/nftables), VPN.
• Management of multiple interfaces and industrial protocols.

Requirements

• Extensive experience with Linux (kernel, user space, networking).
• Programming languages: C, bash, Python.
• Embedded systems: bare metal, RTOS.
• Linux embedded toolchains: Yocto, Buildroot.
• Security: secure communications, code and system hardening, vulnerability patching.
• Familiarity with toolchains and compilers (GCC, CMake, ARM toolchains).
• Advanced debugging: crash analysis (core dump), GDB, tracing tools.
• Ability to diagnose complex issues in embedded environments.
• Capability to create procedures, internal guides, and technical documentation.

Nice-to-have

• Knowledge of C++.
• Experience with CAN, MQTT protocols.
• Knowledge of standards for embedded devices (e.g., RED EN 18031).
• Familiarity with static and dynamic code analysis tools.
