• Implement and enforce best practices for Infrastructure as Code (IaC) using tools such as Pulumi, Terraform, or AWS CloudFormation to achieve consistent and automated deployments.
• Own Bree's security posture - secrets management, IAM, audit logging, encryption at rest and in transit, and access controls for sensitive customer financial data.
• Establish robust monitoring and alerting solutions with Grafana/Datadog to ensure proactive detection and resolution of performance bottlenecks and system issues.
• Drive improvements in system observability, including metrics, logging, and tracing, to enable data-driven decision-making and incident response.
