Principal Engineer/ Kubernetes
We’re looking for a Kubernetes engineer who understands the platform at its roots. Someone who understands how Kubernetes actually works, end to end, from API server → scheduler → kubelet → CRI/CNI/CSI. Edera inserts an isolation layer under Kubernetes, so we need someone who knows where Kubernetes assumes a shared kernel, where those assumptions break, and how kubelet and CRI behave when the world underneath them isn’t the standard container runtime. This requires real depth — the kind you only get from building or debugging Kubernetes internals.
Key Responsibilities
- Own the deep CRI/kubelet integration for our runtime.
- Debug pathological cluster behavior involving kubelet, scheduler, CRI, and CNI.
- Work with the Hypervisor team to align VM lifecycle with pod semantics.
- Build new orchestration primitives for secure multi-tenancy.
- Be the technical authority for how Kubernetes and Edera interact.
- Help define the right abstractions so Kubernetes “just works” on a VM-per-pod runtime.
Qualifications
- Core Kubernetes Depth:
- Strong understanding of API server storage/watches, informers, and controller reconciliation.
- Deep knowledge of scheduler filtering/scoring and admission chain behavior.
- Experience with GC, finalizers, and ownerReference mechanics under load.
- Expert in pod lifecycle and kubelet expectations.
- Strong understanding of kubelet cgroups, QoS, pressure/eviction signals, and CRI lifecycle.
- Clear mental model of probes, logs, exec/attach flows and node-level networking/storage behavior.
- Runtime Integration Basics:
- Knows where Kubernetes assumes shared PID/net/ipc namespaces.
- Understands how CRI relies on Linux container semantics.
- Familiar with device plugins, topology hints, and resource guarantees.
- Strong understanding of CNI IPAM, routing, and teardown behavior.
Why this matter at Edera
- We introduce a new isolation primitive under Kubernetes.
- Kubelet must trust resource guarantees across VM boundaries.
- Scheduler hints must align with virtualized resources.
- CRI must handle VM boot/teardown/logs/exec cleanly.
- Node behavior must remain fully Kubernetes-compliant.
