Using Terraform, GitHub Actions, and DevOps practices, you will build and operate scalable, well-governed platform services in a multi-account AWS environment. While AWS is the primary platform and the target for all new development, the organization maintains a legacy Azure presence that may require occasional support.

Your Responsibilities on the Team

internet/NAT gateways using IaC and CI/CD workflows.
• Build and manage Transit Gateway configurations to support multi-account and multi-region connectivity through infrastructure as code.
• Support AWS Direct Connect implementations for hybrid connectivity between on-premises and cloud environments.
• Implement network security controls including Security Groups, Network ACLs, and VPC endpoint
policies through IaC modules.
• Collaborate with teams that manage AWS Network Firewall and support related configurations as
needed.
• Implement and manage Cloudflare services including DNS, CDN, WAF, and traffic management through infrastructure as code.
• Develop and maintain reusable IaC modules for network and identity infrastructure deployments.
• Build and manage GitHub Actions workflows for infrastructure CI/CD pipelines across networking,
identity, and platform services.
• Implement IAM roles, policies, and trust relationships as code to support least-privilege access patterns across AWS accounts.
• Deploy and manage IAM Identity Center (IAM IC) configurations, Permission Sets, and account
assignments through IaC.
• Troubleshoot network connectivity, latency, and routing issues across AWS and Cloudflare environments.
• Participate in sprint-based support rotations for platform issues as needed.
• Collaborate with cloud engineering, security, and application teams to implement networking and identity solutions based on approved architectures.
• Contribute to documentation, runbooks, and knowledge-sharing within the team.
• Manage account vending processes using enterprise automation tools.
• Maintain and enhance automated provisioning pipelines for infrastructure hosting.
• Define and enforce account guardrails through infrastructure as code policies.
• Drive continuous improvement in cloud usage and automation.

Requirements

• Solid understanding of AWS networking services: VPC, Transit Gateway, Direct Connect, Route 53,
Elastic Load Balancing, and VPC endpoints.
• Familiarity with AWS identity and access management: IAM roles and policies, IAM Identity Center,
Permission Sets, and trust policies.
• Understanding of network security constructs: Security Groups, NACLs, and VPC endpoint policies.
• Experience with or exposure to Cloudflare services such as DNS, CDN, WAF, or Zero Trust is a plus.

• Exposure to AWS Network Firewall concepts is a plus.
• AWS Certifications such as Cloud Practitioner or Solutions Architect Associate preferred; AWS Advanced Networking Specialty is a plus.
