Senior DevOps Engineer

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 Dev Ops team manager, you must have an excellent track record in Dev Ops roles 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 Dev Ops 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 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 Dev Ops 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 shape this journey.
