Embedded Linux Engineer – Boot Time Optimization

Silicon Patterns Pvt. Ltd.; India; On-site; INR 1,200,000 - 2,000,000; Full time

Job summary

Silicon Patterns Pvt. Ltd. is seeking a senior Embedded Linux specialist with hands-on kernel development experience in a Linux-booted environment.

The role emphasizes C programming, boot-time optimization, and Yocto-based image/recipe work to optimize initramfs and systemd behavior. The ideal candidate will demonstrate strong skills in virtualization (Xen or KVM), kernel debugging, and power/performance optimizations across cold and warm boots.

Qualifications

• 5+ years in Embedded Linux system software / kernel development.
• Strong C programming skills.
• Experience with Linux boot-time analysis and optimization in virtualization contexts.
• Deep understanding of Linux boot flow: bootloader, kernel init, initramfs, systemd.
• Yocto Project expertise—image, recipe, and systemd optimization.
• Virtualization experience: Xen (Dom0 preferred) or KVM / QNX Hypervisor.
• Kernel-level debugging and performance tuning.
• Experience with power & performance optimization (cold boot, warm boot, S0ix/S2RAM).
