• Investigate platform failures, performance bottlenecks and systemic issues across complex, multi-tiered architectures.

Skills & Experience

• Proven technical experience in SRE, DevOps and/or Platform Engineering within large-scale, regulated environments.
• Deep technical expertise in on-premises and AWS cloud-native architecture and systems design.
• Strong implementation experience with observability tools and frameworks, including Prometheus, Grafana, OpenTelemetry, ELK/EFK stacks, CloudWatch, Datadog or similar.
• In-depth experience in incident management and production operations.
• Hands-on experience with CI/CD pipelines, Git, automation, scripting and Infrastructure as Code.
• Experience with Python, Go, Ansible, Terraform or similar tools.
• Demonstrable application of agentic AI engineering in observability, incident management and automated recovery.
• Strong understanding of networking, security and reliability engineering principles.
• Experience defining and implementing SLOs, SLIs and error budgets.
• Experience with AWS services such as EKS/ECS, Lambda, API Gateway, DynamoDB, Aurora and S3.
• Experience with SQL Server, Sybase and PostgreSQL, including Aurora.
