▷ (06 / 10 / 2025) Cloud Operations L2 Support Engineer

Job Summary :

We are seeking a highly skilled and experienced Cloud Engineer with a strong Site Reliability Engineering (SRE) mindset to join our team. This role will be critical in ensuring the availability, reliability, and performance of our platform services and applications, particularly those supporting our Radio Access Network (RAN) and Core Network functions deployed on cloud infrastructure. The ideal candidate will possess deep expertise in Kubernetes, cloud operations, and a passion for optimizing complex distributed systems. You will be instrumental in running our production environment, responding to critical incidents, and driving continuous improvement in system reliability and efficiency across both RAN and Core cloud deployments.

Key Responsibilities :

• Platform Reliability & Availability (SRE Focus) :
• Run the production environment by proactively monitoring availability and taking a holistic view of system health for our cloud-based RAN and Core Network platforms.
• Improve the reliability and quality of the system through automation, process refinement, and best practices for both RAN and Core cloud components.
• Measure and optimize system performance to ensure efficient resource utilization and optimal user experience for network services.
• Ensure services are available, the underlying infrastructure is properly functioning and monitor critical applications and related services to guarantee system availability for RAN and Core functions.
• Cloud Operations & Kubernetes Management :
• Design, deploy, and manage Kubernetes clusters and related cloud infrastructure for both RAN and Core Network application deployments.
• Implement and maintain containerization strategies and orchestration best practices for telecom workloads.
• Manage and troubleshoot Robin storage solutions within the Kubernetes environment, supporting the unique storage needs of RAN and Core applications.
• Implement and manage CI / CD pipelines for cloud-native RAN and Core applications.
• Responsible for cloud resource provisioning, scaling, and cost optimization for all deployed network functions.
• Incident & Problem Management :
• Collaborate for high-priority incident tickets (e.g., MIC Reported Incident, Serious / Medium / Small Network Incidents, RIUD Faults), ensuring rapid system recovery for both RAN and Core impacted services.
• Be on standby to interface with developers when issues arise and get escalated, providing immediate technical insights and support for cloud-native network functions.
• Lead Problem Management efforts, including Root Cause Analysis (RCA), for complex incidents affecting RAN and Core cloud deployments.
• Identify bugs and work with development teams to prioritize and implement fixes for cloud-native network elements.
• Monitoring & Alerting :
• Implement and maintain robust monitoring, logging, and alerting solutions for cloud infrastructure and applications supporting RAN and Core services.
• Define and track Service Level Indicators (SLIs) and Service Level Objectives (SLOs) for critical RAN and Core services running in the cloud.
• Automation & Tooling :
• Develop and implement automation scripts and tools to streamline operational tasks, deployments, and incident response for cloud-native RAN and Core components.
• Evaluate and integrate new tools and technologies to enhance operational efficiency.
• Collaboration & Knowledge Sharing :
• Support for Governance Reports, providing technical data and insights on cloud platform performance for RAN and Core.
• Handle customer queries with technical expertise and provide timely resolutions related to cloud-deployed network services.
• Provide training and mentorship to junior team members on cloud technologies and SRE practices, specifically in the context of telecom networks.
• Work closely with development, network, and security teams to ensure seamless service delivery across the entire network architecture.
