SymphonyAI - Senior Site Reliability Engineer - Azure/Oracle Cloud

About the job : Introduction :

You will work on world-class retail supply chain solutions, deploying and running enterprise applications, including GPU-powered AI/ML products, on Azure and Oracle Cloud. These applications run 24/7 and are business-critical : warehouses and stores depend on them for daily operations. In this cloud and SRE role, you will own their reliability : defining and meeting SLOs, responding fast to incidents, troubleshooting end to end, and engineering out recurring problems through automation.

Key responsibilities :

• Own the reliability of business-critical retail supply chain applications on Azure and Oracle Cloud, used 24/7 by warehouses and stores.

• Define and track SLIs and SLOs with product and application teams, using error budgets to balance reliability and release speed.

• Build observability (metrics, logs, traces, dashboards, and actionable alerts) using tools such as Prometheus, Grafana, and Zabbix.

• Provide 24/7 L2/L3 support, act as incident commander on major incidents, and lead root cause analysis and blameless post-incident reviews.

• Troubleshoot end to end across Cloudflare, HAProxy, network, Linux, Docker, Apache TomEE/Java, APIs, and Oracle Database, and quickly isolate the failing layer.

• Diagnose Java application issues using thread dumps, heap dumps, GC logs, and APM traces.

• Perform first-level Oracle Database triage and escalate to the DBA team with clear diagnostics.

• Build and deploy cloud infrastructure (networks, VMs, containers, VPN, ExpressRoute, FastConnect) using Terraform and Ansible.

• Automate away toil, such as deployments, health checks, failover, and routine maintenance, with Python and Bash.

• Plan capacity, tune performance, and test high availability and disaster recovery through regular failover drills.

• Plan and execute production changes with minimal downtime and tested rollback, and maintain runbooks.

Must-have :

• 5 - 10 years in SRE, cloud infrastructure, or production operations, including at least 3 years running production workloads on Azure or OCI.

• Strong cloud expertise (Azure or OCI) across networking (VNet/VCN, VPN, ExpressRoute/FastConnect), compute, storage, and IAM.

• Strong Linux administration (RHEL, Ubuntu) and hands-on Docker experience.

• Hands-on Terraform, Ansible, and Python/Bash automation in production environments.

• Practical SRE experience : SLIs/SLOs, error budgets, toil reduction, 24/7 incident management, and blameless post-incident reviews.
