## About the role

This is the foundation of Runta. You will build the execution engine itself: the layer where agent processes actually run, get snapshotted, get resumed on different hardware, and recover from crashes without losing state.

## What they're looking for

- You’ve built systems at the engine level: an OS kernel, a hypervisor or VMM (KVM, Firecracker, cloud-hypervisor, Xen), a database storage engine, or a language runtime (JVM, Go runtime, V8 internals)
- Muscle memory for memory layout, syscall boundaries, context switch costs, and crash recovery: you’ve debugged problems where timing and state transitions mattered, not just logic
- You can reason about copy-on-write, page sharing, and dirty tracking from first principles
- Comfort working close to the metal in Rust, C, or C++
- Staff level: you’ve also owned the architecture of such a system and made trade-offs you can defend years later
- Nice to have: CRIU or live-migration experience, io_uring, experience making cold starts fast at scale
