Senior DevOps Engineer

10+ years of experience in DevOps, Cloud Infrastructure, or Platform Engineering, with ownership of production AWS environments. Deep expertise in AWS services (ECS, ALB, VPC, RDS, S3, ElastiCache, IAM, CloudWatch). Proven experience with Infrastructure as Code (IaC) — Terraform (preferred) or CloudFormation. Hands-on experience designing highly available, scalable, and cost-efficient architectures (multi-AZ, auto-scaling, HA patterns). Strong understanding of networking fundamentals (VPC design, routing, VPN, NAT, security groups, load balancing). Proficiency in CI/CD pipelines — GitHub Actions, CircleCI, or equivalent; building container-based pipelines for AWS deployments. Experience with container orchestration (preferably ECS) and image lifecycle management. Experience supporting and deploying Ruby on Rails applications in containerized or cloud-based environments. Competence in scripting or automation (Python, Bash, Go, or similar). Experience implementing or integrating observability tooling — metrics, tracing, and centralized logging (e.g., Datadog, CloudWatch, ELK). Strong collaboration skills — partnering with SRE, Security, and Application teams. Track record of driving migrations or modernization projects (e.g., Heroku to AWS, monolith to containers).

Design, build, and maintain a fully codified AWS environment using Terraform with zero manual changes. Architect scalable, secure, and cost-efficient AWS infrastructure (networking, compute, storage, IAM). Drive multi-account architecture, VPC design, and environment standardization. Containerize existing applications and ensure production-grade deployments in AWS. Build migration playbooks, rollout strategies, and safe cutover processes. Modernize CI/CD pipelines to use container-based builds and deployments. Implement self-service deployment workflows with automated rollback capabilities. Establish pipeline templates, shared build images, and guardrails for all engineering teams. Own Terraform modules, standards, and tooling to ensure reproducible and auditable infrastructure. Enforce best practices for versioning, module reuse, secrets management, and CI-driven Terraform plans/apply. Create automated checks to eliminate drift and prevent manual changes. Partner with the SRE Engineer to deliver end-to-end observability: logs, metrics, traces, dashboards, and SLOs. Standardize instrumentation across services and environments. Improve system reliability, alert quality, and on-call readiness. Build and improve internal platform tooling to speed up local development, testing, and deployments. Provide clear, intuitive interfaces for application engineers to use infrastructure safely and independently. Remove friction from engineering workflows and reduce deployment times/cycle times. Implement IAM least privilege, secrets management, and environment isolation patterns. Ensure CI/CD pipelines and containers align with security & compliance standards. Partner with Security Engineering to embed controls into infrastructure and deployments. Establish runbooks, standards, and automation for operational tasks (backups, failovers, DR plans). Continually reduce operational burden through tooling, automation, and resilient architectures. Monitor cost drivers and implement cost optimization strategies across AWS and CI/CD. Work closely with Application Engineering, SRE, Security, and Product teams to support new features and roadmap goals. Translate engineering requirements into scalable infrastructure designs. Participate in architecture reviews, incident postmortems, and planning cycles.
