Site Reliability Engineers (SREs) are responsible for keeping all user-facing services and other production systems running smoothly. SREs are a blend of pragmatic operators and software craftspeople that apply sound engineering principles, operational discipline, and mature automation to our environments and the codebase. Specialize in systems, whether it be networking, the Linux kernel, or some more specific interest in scaling, algorithms, or distributed systems.
Operations:
• Maintaining the availability of the applications.
• Use your on-call shift to prevent incidents from ever happening.
• Run our infrastructure with Chef, Terraform and Kubernetes.
• Make monitoring and alerting alert on symptoms and not on outages. On CloudWatch, Splunk, AppDynamics, Dynatrace, Graphana, Kibana and DataDog and Prometheus.
• Document every action so your findings turn into repeatable actions–and then into automation.
• Excellent analytics skills to improve the product as much as possible.
• Improve the deployment process to make it as boring as possible.
• Design, build and maintain core infrastructure pieces that allow services scaling to support hundreds of thousands of concurrent users.
• Debug production issues across services and levels of the stack.
• Plan the growth of the infrastructure.
• Think about systems - edge cases, failure modes, behaviors, specific implementations.
• Performing all possible technical troubleshooting steps on mobile platforms and back end systems to solve the problems and service requests, including testing and QA of fixes.
• Determine if issues are application or software (triage)
• Regular Deployment activities for CMS enhancements and new releases
• Developing scripts to automate system activities
• Monitoring configuration
• User management configuration
• CMS (application) Management and configuration
• Troubleshooting & facilitating the Infrastructure and connectivity issues remotely for Vodafone markets (i.e., Vodafone Portugal, Greece, Ghana, etc) (DNS,Proxy, Firewalls)
• Utilizing the existing team applications and tools (knowledge base, Documentation database) to solve the incidents
Quality:
• Ensure that the technical solution and root cause are clear and logic
• Prioritizing and managing several open cases at one time based on agreed Service Levels.
• Ensure that all incidents are solved within the agreed SLA
• Update the technical documentation and the team knowledge base.
