• Participating in code reviews and upstream contributions

Requirements

• 2–4 years of experience in embedded systems development (C)

• Strong understanding of memory, pointers, and low-level programming concepts

• Experience working with Linux (CLI, debugging)

• Solid knowledge of Git (branching, rebasing, code reviews)

• Experience with build systems (Make, CMake, Yocto, or Kconfig)

• Hands-on debugging skills (GDB, logs, issue analysis)

• Understanding of CPU architectures (x86, ARM, or RISC-V)

• Ability to read technical documentation and schematics

• Good command of English (written and spoken)

Nice to Have

• Experience with coreboot, UEFI, EDK II, or U-Boot

• Knowledge of Rust or Python

• Understanding of Trusted Computing (TPM, Secure Boot)

• Experience working with hardware interfaces (UART, SPI, I2C, JTAG)

• Contributions to open-source projects (GitHub / GitLab, PRs, reviews)

What We Expect

• Ownership and accountability for your work

• Ability to work with large and unfamiliar codebases

• Proactive problem-solving mindset

• Willingness to share knowledge and collaborate within the team

What We Offer
We offer the opportunity to work on open-source projects and collaborate with the community of world-class industry leaders, as well as work with some of the most prominent vendors to build your own portfolio through contributions. As a team member, you'll impact the product and its final shape with opportunities for professional development, flexible working hours, and employment conditions.
We also provide training and certification to help our team members build their skills and advance in their careers. Our comprehensive benefits package includes medical care, financial support for sports cards, and group insurance.
