Role Overview
We're a well-funded, stealth startup building a new end-to-end personal computing platform. For this role, the primary responsibility is to build, optimize, and maintain the core virtualization and kernel stack that powers our platform. You will have deep ownership over host and guest kernel interactions, identifying performance bottlenecks, and implementing novel solutions to mitigate hardware virtualization overhead.
Whether it’s tackling pathological memory access overhead by implementing advanced hugepage alignment techniques (e.g., coordinating host/guest hugepage backing to eliminate TLB misses), optimizing CPU scheduling, or improving I/O virtualization, your goal is to push the boundaries of virtualization performance, and contribute those improvements directly back to the broader Linux ecosystem.

Responsibilities
- Virtualization Stack Ownership: Design, implement, and optimize host and guest OS features to maximize throughput and minimize latency in a hardware-accelerated virtualization environment.
- Open Source Stewardship: Heavily engage with the upstream community. Prepare, submit, and shepherd kernel patches through Linux kernel mailing lists, advocating for our architectural improvements to become part of mainline Linux.
