Engineering Tech Lead (vNode)

As an Engineering Tech Lead at vCluster Labs, you aren't just shipping container runtime features; you are defining how Kubernetes operators get VM-grade tenant isolation without the VM tax. vNode replaces virtual kubelets and microVMs with a runtime built on Linux user namespaces and seccomp, and the person in this seat owns where that runtime goes next. You will partner directly with the vNode founding engineers, run the technical bar for the team, and ship the work that decides whether AI Clouds and regulated enterprises can adopt vNode as their default isolation layer.

As an Engineering Tech Lead, your role will include:

• Owning the vNode technical execution: Drive the architecture for how vNode wraps containerd, integrates with the kubelet, and exposes safe isolation primitives. You will set the bar for what ships, what gets deferred, and what gets redesigned.

• Going deep on container runtimes and isolation: Lead the work where vNode meets containerd, Kata Containers, gVisor, runc, and the kernel. You will be the person who can explain (and improve) exactly what happens between a Pod spec and a process running under a constrained user namespace with a tight seccomp profile.

• Shipping the kubelet integration surface: Own how vNode plugs into the node lifecycle: CRI, kubelet device plugins, cgroups v2, eviction, and the rough edges between Kubernetes' node model and a runtime that does not assume one tenant per node.

• Raising the engineering bar: Run technical design reviews, set the pattern for testing isolation guarantees, and mentor the engineers shipping alongside you. You are not a people manager, but you are the engineer the team copies.

• Being Customer Zero for vNode: Run vNode against vCluster Platform tenant clusters internally before customers see it. You will close the loop between what AI Cloud operators need and what vNode actually does in production.

• Representing vNode externally: Contribute upstream where it matters (containerd, runc, Kubernetes SIG-Node), write the technical posts that explain why namespace-based isolation is the right answer, and represent vCluster Labs at KubeCon-class venues when the timing is right.

This role could be a fit for you if you bring:

• Deep container runtime experience: You have shipped production work against containerd directly, not ju
