About the role

Key responsibilities & impact

Ensure the reliability, performance and availability of connectivity between systems by operating, diagnosing and evolving networks in distributed, hybrid and cloud environments, with a focus on traffic analysis, advanced troubleshooting and communication architecture between services.
**Strategic AWS environment management:**
Operate and evolve complex, reproducible environments with high availability, performance and horizontal scalability, using services such as EC2, ECS, Lambda, RDS and S3.
**Reliability and observability:**
Define, implement and evolve end-to-end observability practices (SLIs, SLOs, SLAs) with tools like New Relic, CloudWatch and custom dashboards;
Proactively identify bottlenecks and incidents.
**Connectivity and network performance:**
Diagnose and resolve latency, packet loss and throughput issues in distributed environments;
Troubleshoot DNS, VPNs, firewalls and load balancers (L4/L7);
Analyze communication flows between services (cloud, on-premises and external integrations);
Support the definition and evolution of connectivity architecture between systems.
**Automation and CI/CD:**
Design, maintain and optimize robust and secure pipelines (Jenkins, Bitbucket, GitOps) for continuous delivery of microservices and serverless workloads.
**SRE culture and continuous improvement:**
Promote blameless post-mortems, chaos engineering and automation of operational tasks to reduce toil and increase team efficiency.
**Security and governance (DevSecOps):**
Integrate best practices for IAM, secure networking, encryption, traffic control, vulnerability monitoring and compliance into the application lifecycle, including connectivity troubleshooting and communication analysis between services.
**Documentation and knowledge sharing:**
Create and maintain clear documentation on architecture, automations, incidents and runbooks, driving autonomy and improving onboarding.
