  • Perform board bring-up and integrate new hardware platforms into Linux
  • Develop and configure Device Tree, platform drivers, and user-kernel interface
  • Debug kernel panics, hardware faults, and interface-level issues using tools like dmesg, kgdb, ftrace, perf, etc.
  • Optimize driver performance, power usage, and boot time
  • Collaborate closely with hardware, board design, and application teams
  • Contribute to Linux kernel upstreaming (optional based on role)
  • Maintain kernel logs, configuration, and build scripts (Makefiles, KConfig)
  • Participate in Linux OS upgrades, BSP customization, and security patching
