What you'll do

• Design, provision, and manage AWS infrastructure across dev, staging, and production using Terraform modules and remote state.
• Build and maintain CI/CD pipelines for fast, reliable, repeatable deployments across multiple services.
• Containerize applications with Docker and orchestrate workloads on ECS or Kubernetes with sensible scaling and rollout strategies.
• Set up monitoring, alerting, and centralized logging so issues are caught and triaged before customers feel them.
• Own cloud security end to end: IAM hygiene, secrets management, network segmentation, encryption in transit and at rest, and patching across client accounts.
• Harden infrastructure against common attack surfaces, run vulnerability scans on containers and dependencies, and stay aligned with industry security standards.
• Partner with engineering teams to streamline release cycles, reduce lead time, and remove friction from day-to-day workflows.
• Document architecture, runbooks, and post-incident learnings so the platform and the team scale together.

What we're looking for

• 3+ years of hands-on DevOps or Cloud Engineering experience in production environments.
• Strong AWS fundamentals: VPC, EC2, ECS/EKS, RDS, S3, IAM, CloudWatch, Route 53, ALB/NLB.
• Production experience with Terraform, including modules, remote state, drift management, and multi-environment patterns.
• Comfort with Docker, container registries (ECR), and image security and patching practices.
• CI/CD experience with Jenkins or GitHub Actions, including secret handling and approval gates.
• Solid grasp of cloud security: IAM, secrets management, network policies, TLS, and least- privilege design.
• Exposure to vulnerability scanning, container hardening, and security best practices in CI/CD pipelines.
• Scripting in Python or Bash for automation, glue, and small internal tools.
• Solid Linux system administration and networking fundamentals.
