DevOps Engineer

Overview

You’ll be a 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 a proven track record in a DevOps or similar engineering role and the drive and attitude to succeed. Zen are committed to investing in and developing you – we believe that everyone can lead and the way we do has a huge impact on our people and play a vital part in our success.

The DevOps team will be responsible for the design and implementation of applications' build, release, deployment and configuration activities. 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 support incidents so they are run smoothly and help ensure that operational knowledge is available and shared. You’ll escalate to Senior and Lead DevOps engineers where needed, 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 Senior and Lead DevOps engineers, Systems Engineers and developers leveraging frameworks, standards, and defined operational process to make the unfamiliar comfortable and familiar. Over time we’ll increasingly leverage SRE principles to further optimize and enhance capabilities – it’s a great opportunity to get in at the start and help shape this journey.
