The Main Responsibilities

Production Support & Incident Management

• Help define and improve the processes and best practices for incident management within the customer facing applications.
• Implement AI systems and automations to assist during ongoing outages and triage potential ones. You will work with the development teams to ensure that they have all the data normally needed during an outage at their fingertips including preliminary analysis by AI.
• Design and implement improved SRE processes to handle incidents. From proactive analysis, faster response, automatic remediation, AI guided analysis, partially automatic root cause analysis.

Performance Optimization

• Monitor system performance and proactively identify bottlenecks or degradation using AI-driven observability and anomaly detection tools.
• Implement tuning strategies across application layers, databases, and infrastructure. 
• Drive initiatives to improve latency, throughput, and resource utilization.

Monitoring & Observability

• Deploy improved alerting for Lumen Connect in depth, focusing on outside in but including early indicators for fulfilment and other areas. Combining traditional monitoring with AI-based anomaly detection and noise reduction.
• Proactively monitor the errors and performance on Lumen Connect. Implement rules to detect deviations, implement improvements together with the teams.
• Design and maintain dashboards, alerts, and metrics using tools like Datadog, AppInsights, CloudWatch, or similar.

Automation & Infrastructure as Code

• Develop and maintain automation scripts and tools for deployment, scaling, and recovery, leveraging AI-assisted code generation and validation tools
• Use Terraform, or similar IaC tools to manage AWS resources.

Reliability Engineering

• Perform an in-depth analysis of the overall system and its dependencies, implementing techniques to increase the global availability, reduce the reliance on unstable dependencies and guide ecosystem improvements.
• Champion SRE principles such as SLIs, SLOs, and error budgets.
• Advocate for resilient architecture and fault-tolerant design patterns, incorporating AI-assisted design reviews and architecture evaluation.
• Help define and improve better SRE processes and lead significant improvements in reliability for the Lumen Connect platform.

Collaboration & Communication

• Work closely with software engineers, DevOps, and product teams t
