Job description

Pod 6 — Linux — Lead

Pod / Track Pod 6 — Linux

Role Title Lead — Linux Kernel & BSP

Experience 8 – 10 years

Primary Location Hyderabad, India (Transition phase); HCLTech Offshore Delivery Center thereafter

Work Model Physical co-location at Hyderabad mandatory during Transition (Month 1–3) for knowledge transfer and hardware/lab access; delivery shifts to HCLTech's Offshore Delivery Center (ODC) from Shadow (Month 4–6) onward.

Role Summary
Own Linux kernel and BSP sustenance — version upgrades, device-tree maintenance, upstream kernel.org contribution, and kernel driver defect resolution across the platform.

Key Responsibilities

• Sustain the kernel, device tree, and board support package.
• Own the HLOS boot hand-off from the bootloader/Coretech layer through kernel initialization.
• Tune kernel-level performance — memory footprint and boot-time optimization — and support OTA integration at the kernel/HLOS layer.
• Manage kernel version upgrade cycles across platform releases.
• Upstream patches to kernel.org and vendor Linux trees, aligned with the platform's upstream-first open-source direction.
• Triage kernel panics and crash dumps.
• Maintain the kernel security-patch cadence and CVE response process.
• Mentor the pod's Senior Engineers on kernel debugging and upstream contribution practice.

Must-Have Skills

• 8–10 years Linux kernel engineering.
• Linux kernel internals.
• Device tree authoring.
• Upstream kernel contribution process (kernel.org).
• Kernel debugging (kdump/crash).
• Security patch triage and CVE response.
• Yocto/OpenEmbedded HLOS build experience; boot-time and memory performance profiling.

Good-to-Have Skills

• Upstream kernel.org maintainership or a significant patch history.
• Yocto/OpenEmbedded layer maintenance.
• Real-time kernel (PREEMPT_RT) experience.
• Embedded security-patching automation tooling.
• OTA update integration experience at the kernel/HLOS layer.
