ix is building the infrastructure layer for sandboxed code execution. we are a small, funded team that writes everything in rust on a linux-first greenfield codebase with zero legacy constraints.

the stack

• hypervisor we wrote our own VMM on top of KVM. it can fork a running sandbox in milliseconds.
• storage all data flows through a content-addressable storage engine with tiered caching and automatic deduplication across tenants.
• transport the storage fabric runs over libfabric so we can move from TCP to RDMA without rewriting application code.
• filesystem guests see local filesystems backed by the content-addressable storage layer.
• nix we vendor a custom fork of snix (nix reimplemented in rust) for reproducible builds.
• kernel we maintain a custom linux 6.19 kernel with patches for features upstream does not support yet.
• tooling we maintain a custom clippy so that agents write code that meets our standards without waiting on upstream.

passion > intelligence > knowledge. no specific domain knowledge is required, though it helps. we care more that you are obsessed with building systems that work beautifully, that you notice when something is slightly wrong, and that you will not rest until it is better than it was.

we work remotely and do not run interview puzzles. send us something you have built or a problem you have thought deeply about.
