• Operate effectively in ambiguous problem spaces where both the problem and the solution need to be defined.

You're a good fit if you have

• Deep familiarity with virtualization technologies such as Firecracker, QEMU, or Cloud Hypervisor, and an understanding of the tradeoffs between them.
• Experience with distributed storage systems (e.g., Ceph) and a strong grasp of low-level file system performance, I/O tuning, and storage reliability at scale.
• Comfort working at the kernel and filesystems level: experience with eBPF, cgroups, namespaces, or similar Linux primitives.
• Track record of leading through influence and shaping technical direction while operating as an individual contributor.
• Strong communication skills, with the ability to explain complex systems-level concepts to engineers, leadership, and non-technical stakeholders.
