About the DevOps Team

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.

What You’ll Do

• 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

Who You Are

• 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

Required Technical Qualifications

• 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)
