Senior DevOps Engineer

The Senior DevOps Engineer will establish and employ Continuous Integration practices and tools such as Jenkins or other CI tools. In this role, you will have experience using configuration management and infrastructure automation tools such as Terraform, Ansible, Puppet (or other such tools) in creating continuous delivery systems and employ industry Continuous Delivery patterns and collaboratively work with other members to achieve successful continuous delivery solutions. You will also have experience programming and scripting in a high-level language such as PowerShell script, Ruby, Python, Java, C# or other language to script installation, configuration, and provisioning and will be writing scripts to build code, docker images and deploy and orchestrate containers (Docker and Kubernetes). You will provide continuous delivery solutions in cloud and on-premise environments. You are also responsible for defining and implementing effective monitoring and alerting strategies for Elixir Infrastructure and platform. The Senior DevOps Engineer will be responsible for mentoring and teaching existing team members. As such, the ideal candidate must have experience clearly explaining solutions to complex problems and demonstrate the ability to lead and impart knowledge effectively to junior resources.
