About the Role
We are seeking an experienced Cloud Infrastructure Engineer to design, deploy, and administer cloud environments with a strong emphasis on virtualization, automation, and security.
This role owns the full lifecycle of cloud infrastructure — from virtual machine provisioning and network architecture to Infrastructure as Code (IaC) deployments and continuous monitoring.
The ideal candidate brings hands-on experience managing AWS and/or Azure environments, operating container platforms, and translating operational complexity into scalable, secure solutions. Experience working in regulated or compliance-driven industries (e.g., healthcare, defense, finance) is a strong plus.
Key Responsibilities
Cloud Infrastructure & Virtual Systems Administration
- Administer and maintain AWS and/or Azure environments, including day-to-day operations of virtual machines, networking, and storage.
- Manage VPCs, subnets, routing tables, security groups, NACLs, and private networking constructs
- Deploy, maintain, and optimize EC2 instances, RDS, S3, IAM, KMS, Secrets Manager, and CloudTrail
- Build and manage hardened VM images (AMIs / golden images) for consistent, repeatable deployments
- Implement and support high availability, auto-scaling, and disaster recovery configurations
- Support multi-account or multi-subscription cloud governance structures (e.g., AWS Organizations, Azure Management Groups)
Infrastructure as Code (IaC)
- Design and maintain infrastructure using Terraform, including modular design, remote state management, and workspace strategies
- Lead or support migrations from legacy IaC tooling (e.g., CloudFormation) to modern frameworks
- Enforce policy-as-code guardrails and maintain version-controlled infrastructure repositories
