Senior Kubernetes and Open Source Platform Engineer

About the role

Zappsec advises clients who run their own Kubernetes platforms. Their engineers operate the clusters. You tell them how to operate them well, and you take the problems they cannot solve. The platforms in scope are self managed rather than cloud managed. Expect Rancher RKE2 on bare metal or private infrastructure, with Harbor, GitLab Runner, MetalLB, and OpenSearch around it.

What you'll do

• Advisory and escalation support Take escalations on Kubernetes, RKE2, Harbor, GitLab Runner, MetalLB, and OpenSearch
• Work alongside client engineers while they apply the fix, and explain why it works
• Reproduce complex failures in a lab environment when the client environment cannot be disturbed
• Decide when an issue belongs upstream, then prepare the bug report or vendor case with the evidence attached
• Track recurring escalations and name the underlying platform weakness that produces them
