Full Time

We are seeking a highly skilled and experienced Linux Kernel and MACsec Engineer to develop, debug, and maintain the core operating system and security features for our MACsec-enabled industrial products.

This role involves deep technical work on the Linux kernel, device drivers, and system-level software to ensure robust performance and security of our hardware platforms.

Key Responsibilities

  • Design, implement, and maintain Linux kernel drivers and modules for MACsec hardware, ensuring compliance with IEEE 802.1AE standards and security best practices.
  • Debug and resolve complex issues within the Linux kernel, boot process, and user-space applications on embedded devices.
  • Develop and manage Linux kernel packages, boot sequences, and patches for updates and new feature implementation.
  • Optimize system performance, including memory management, I/O, and networking, with a specific focus on security within the kernel.
  • Conduct security threat modeling, vulnerability assessments, and penetration testing for Linux-based embedded systems.
  • Collaborate with cross-functional teams to integrate software solutions, conduct code reviews, and mentor junior engineers.
  • Manage the full lifecycle of operating system updates, ensuring smooth and secure deployment to MACsec devices.
  • Create and maintain technical documentation related to kernel development processes, OS updates, and security features.
