As a Custom OS and Linux Intern at Grid OS, you will work at the core of our embedded and custom operating system development. You will contribute to system-level programming, Linux-based firmware customization, and work directly with real hardware.

Key Responsibilities:

· Develop and debug system-level programs in C/C++.

· Work with low-level Linux OS components including process and memory management.

· Understand and navigate Linux file systems, kernel vs user space, and syscalls.

· Use CLI tools such as bash, vim, grep, strace, gdb, top, etc. for development and troubleshooting.

· Work with /proc and /sys interfaces to interact with Linux internals.

· Modify or interpret Device Trees for embedded Linux projects.

· Write basic shell scripts to automate system tasks.

· Use systems like Make, CMake, or Autotools to manage and build software projects.

Requirements:

· Strong programming skills in C/C++, especially in system-level contexts.

· Solid understanding of Operating System fundamentals, including process and memory management.

· Familiarity with Linux internals, including system calls and file system architecture.

· Hands-on experience with the Linux command-line environment and common development tools.

· Understanding of the difference between kernel space and user space.

· Knowledge of shell scripting and how to use it to manage and automate system tasks.

· Comfort working in a low-level, detail-oriented environment that requires patience and precision.

Good to Have:

· Experience with Buildroot or Yocto for building embedded Linux distributions.

· Familiarity with cross-compilation workflows.

· Prior work with embedded systems or SBCs like Raspberry Pi, BeagleBone, Rockchip, etc.

· Basic knowledge of device drivers and communication protocols (GPIO, I2C, SPI, etc.).

· Experience writing kernel modules.

· Exposure to bootloaders like U-Boot or GRUB.

· Experience with debugging tools such as JTAG, OpenOCD, or gdbserver.

· Understanding of Linux init systems like systemd or SysVinit.

This Role May Not Be for You If:

· You’re uncomfortable working at the system or kernel level.

· You prefer abstracted, high-level programming over OS-level problem-solving.

· You’re not ready to dive deep into technical documentation or Linux internals.

· You’re looking for a simple or surface-level programming internship.
