Senior K8s and Private Cloud DevOps Engineer

Job Overview

This is a hybrid development and sysadmin/operational position responsible for continually enhancing and extending the Kubernetes implementation in our private cloud, in response to evolving business requirements. The position will report to the Director of Development and will work closely with DevOps staff, engineering management and IT.

If you’re interested in databases, data platforms and high performance stateful software, this job is for you: You’ll want to work with and learn from some of the brightest people in industry, grow your skills and learn how products are built and shipped. You jump at the opportunity to master new technologies and keep up to date. You take initiative to, and get satisfaction from, collaborating with other developers to deliver the best possible experience. You have a bias for action with a “can-do” attitude.

Responsibilities

You will work on continually extending our private Kubernetes implementation to improve reliability, automate administrative tasks, and adapt the implementation and infrastructure to support newer workloads, platform types and use cases. Example work includes:

• Implement and automate NPD, and extend NPD in Golang with custom probes for our infrastructure.

• Implement fully automated, standardised certificate management using cert-manager and simplify the security architecture.
