Role Description As a Senior DevOps Engineer at Rain, you will play a central role in designing, building, and operating our cloud infrastructure as we continue to scale to millions of users globally. You will work alongside a small, high-performing cloud team to drive automation, improve observability, and ensure the reliability and security of our platform. This role goes beyond keeping the lights on — you will actively shape how we build and operate infrastructure and influence architectural decisions. - Design, build, and maintain scalable, secure cloud infrastructure on AWS using Terraform and Terragrunt (IaC, Infrastructure as Code) - Manage and evolve our Kubernetes (EKS) clusters — including node group management, autoscaling with Karpenter, and workload reliability - Own and improve our CI/CD pipelines (GitLab CI), ensuring fast, reliable, and secure delivery - Drive observability initiatives: metrics, logging, alerting, and dashboards using Prometheus, Grafana, and related tooling - Support and evolve our Kafka infrastructure in collaboration with backend engineering teams - Champion infrastructure-as-code practices, ensuring consistent, reviewed, and well-documented changes - Respond to production incidents, lead post-mortems, and drive improvements in incident response processes - Collaborate with backend, security, and product engineering teams to support their infrastructure needs - Leverage AI-assisted tooling (e.g., GitHub Copilot, AI-powered incident analysis, LLM-based automation) to increase productivity and quality Qualifications - You bring 5+ years of experience managing large-scale production environments and aren't afraid of architectural complexity - You have a "code everything" mindset, replacing manual tasks with scalable, DRY Infrastructure as Code (IaC) - You understand the "why" behind Kubernetes internals and cloud networking, not just the "how" of deployment - You communicate complex infrastructure concepts clearly to both engineering peers and business stakeholders - You treat security, secrets management, and observability as core features, not afterthoughts Requirements - Advanced AWS & EKS: Deep proficiency in EC2, RDS, S3, IAM, and VPC networking, specifically within multi-account EKS environments - Kubernetes Internals: Hands-on experience with CNI, RBAC, Affinity/Taints, and managing complex workloads (StatefulSets/DaemonSets) - IaC Mastery: Proven ability to scale infrastructure using Terraform and Terragrunt with modular, reusable patterns - CI/CD & Helm: Expertise in designing secure GitLab CI pipelines and managing versioned Helm charts across environments - Observability: Proficiency in building dashboards and alerting logic using Prometheus and Grafana - Linux & Scripting: Strong Bash skills for environment management (Python proficiency is a significant plus) Company Description Rain is the world's first AI Financial Health Platform, serving 3.5 million employees at leading organizations like McDonald's, Marriott, and T-Mobile.
