Overview
You’ll be a senior member of the Engineering Reliability Team that will work closely with Zen’s development, engineering, and operations centre teams. You’ll Work alongside the Development and engineering teams, to support, maintain, and consistently improve the development estate so the development teams can focus and innovate constantly to drive Zen’s business and the teams’ priorities.
Reporting to the DevOps team manager, you must have an excellent track record in DevOps roles and the drive and attitude to succeed.

Other responsibilities include working within multi-functional teams to gather requirements, evaluate tools, implementing/updating solutions, building and executing test plans, provision environments, application performance reviews, assist migration of Legacy systems, and triaging and fixing operational issues.
You’ll ensure incidents are run smoothly and ensure that operational knowledge is available and shared. As a senior you will be a point of escalation, demonstrating problem solving skills, the ability to learn quickly and adapt your skills and knowledge.
As a service provider we operate many technologies, so you’ll have the skills to work with experienced Lead DevOps engineers, Systems Engineers and developers leveraging frameworks, standards, and defined operational process to make the unfamiliar comfortable and familiar.
