Senior DevOps Engineer

**This role is not eligible for visa sponsorship. Candidates must have the unrestricted right to work in the UK to be considered**

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. 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 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. 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.

Objectives

• Deliver continuous incremental improvement of systems and infrastructure
• Take end to end ownership and responsibility for development infrastructure and systems
• Be a technical escalation point and eventually be part of a 24/7 escalation rota
• Document as you go – enough so your colleagues can follow what’s been done and why
• Drive tasks forward with energy and enthusiasm
• Create proactive monitoring solutions using standard tooling - mainly Zabbix and Elastic
• Conduct RCA (Root Cause Analysis) for incidents
• Develop standard operational procedures and documentation
• Develop and maintain self-managing infrastructure services and dashboards.
• Identify cost-saving opportunities
• Provide advice on DevOps standards and practices

• Provide coaching and mentoring to Software and DevOps Engineer peers

• Worked in complex networking and firewall environments
• Production use of multiple AWS capabilities and Kubernetes debugging
• Demonstratable experience in dealing with technical debt effectively

• Ability to influence others in matters of standards and best practice, especially individuals outside of our team
• Comfortable working with automation tools (Puppet, Git) and CI/CD pipelines (Azure DevOps) with complex integrations and test frameworks
• Comfortable with Elasticsearch log standardisation, Kibana dashboard creation and data analysis skills
• Able to code to a good level - this isn’t a developer role but you need scripting skills to succeed

• Certificate management and automation
• Strong troubleshooting and diagnosis skills
• Able to write documentation that covers what your peers and operations need to know

• Strong attention to detail
• Happy working and supporting a small closeknit team
• Take and give feedback to tune future actions and behaviours
• Embrace and demonstrate Zen values

You will be influencing and contributing to Zen’s long-term goals and joining a family that believes business should be a force for good. We’re a company committed to improving the lives of our people, creating a better future through our community and charity work, and ensuring that we look after our environment.

Perhaps that’s why we’re officially a Great Place to Work and have achieved Carbon Neutral Plus status and B Corp Certification!
