- Help build and enhance our observability platform which captures both system stability and user behavior that feeds into our business intelligence and ai platform.
- Manage and improve our CI/CD and AWS EKS infrastructure using Terraform for cloud provisioning and Ansible for on-premise Kubernetes cluster management.

What We're Looking For- 5+ years of professional software engineering experience, with demonstrated ownership of complex, production systems.
