Position Overview

The Sr Kubernetes Engineer is a hands-on technical role responsible for designing, building, and operating Zelis’ Kubernetes platform(s). This role is central to our cloud modernization efforts and requires deep experience running Kubernetes in production.
You will act as the technical authority for Kubernetes, directly contributing to platform architecture, security, reliability, developer experience, and cost optimization. The role is expected to be highly hands-on, including implementation and operational support.
The position also offers a future path into people management for those who are interested, though it may remain a primarily technical role.
You will partner closely with engineering, security, and infrastructure teams to deliver a secure, scalable, and reliable Kubernetes platform.
