Principal Kernel Engineer – Linux Kernel Performance & Power Optimisation
We are currently partnered with a global technology leader developing next-generation mobile computing platforms and intelligent operating systems. As part of their advanced systems software organisation, they are looking to hire a Principal Kernel Engineer to drive deep Linux kernel performance, power efficiency, and system optimisation across flagship mobile platforms.
Key Responsibilities Optimise Linux kernel memory management subsystems including buddy allocator, SLUB, page reclaim, MGLRU, compaction, transparent huge pages, page fault handling, TLB management, and copy-on-write behaviour Drive scheduler performance improvements across heterogeneous ARM big.LITTLE and DynamIQ architectures, focusing on task placement, load balancing, wakeup latency, energy-aware scheduling, and CPU frequency management Analyse and optimise synchronization mechanisms including mutexes, futexes, spinlocks, qspinlocks, RCU, seqlocks, per-CPU data structures, and memory ordering behaviour
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
