Senior Linux Embedded Systems Engineer
Reference point for the design, configuration, and maintenance of Linux embedded systems, with advanced expertise in integrating third-party modules and components.
Must have in-depth knowledge of Linux in all its components and the ability to tackle any challenge related to the operating system:
* 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.
