About The Position

Mercury is seeking a Senior Infrastructure Engineer to help shape and scale its cloud infrastructure. The role will build ephemeral environments in Kubernetes, develop foundations that allow non-technical users to ship changes through an agent coding platform, and create safe, secure networks for platform teams. The engineer will build Mercury’s Infrastructure Platform to support the growing engineering organization, making it AI-friendly and usable by both people and agents. The position uses AWS services including EC2, RDS, IAM, networking, ECS, and EKS; Terraform for infrastructure as code; and Prometheus, Grafana, and OpenTelemetry for monitoring and observability. It also involves GitHub and GitHub Actions for version control and CI/CD, as well as building frameworks for safe use of AI in infrastructure by agents and the users who initiate them. As a senior team member, the engineer will lead key infrastructure projects, break down complex initiatives, and help define infrastructure strategy through detailed RFCs and technical specifications.
