Senior AWS Cloud Infrastructure Engineer (Terraform / IaC) - Telecom Networking

Job Title: Senior AWS Cloud Infrastructure Engineer (Terraform / IaC)

Location: Philadelphia 5x/Week

Employment Mode: Contract – W2

Telecom Domain Mandatory

Role Overview

We are seeking a Senior AWS Cloud Infrastructure Engineer who excels at designing, provisioning, and managing cloud-native infrastructure on AWS using Terraform and IaC best practices. This is primarily a cloud infrastructure role — you will own the end-to-end design and automation of our AWS environment, from network topology and security posture to serverless and containerized workloads. The ideal candidate is a Terraform practitioner first, with deep AWS expertise and the ability to enforce governance, repeatability, and security through code.

Key Responsibilities

• AWS Architecture & Cloud Design: Architect and own highly available, multi-AZ environments across core AWS services — VPC design, subnet segmentation, Transit Gateway, Route 53, and IAM trust boundaries. Deep hands-on experience with the AWS Serverless stack (Lambda, DynamoDB, API Gateway, S3) is a strong plus.
• Terraform & Infrastructure as Code (IaC): Design and maintain modular, reusable Terraform configurations across multiple AWS accounts and environments. Enforce module standards, remote state management (S3 + DynamoDB locking), and workspace-based environment promotion strategies.
• Container Orchestration: Manage microservices deployment and scaling using Docker and Kubernetes (EKS).
• Performance Optimization: Manage and tune Amazon ElastiCache (Redis) for high-speed data retrieval and session management.
• Security First: Implement "Security as Code" within Terraform and AWS. Conduct regular audits to fix security gaps, manage IAM roles, and ensure VPC isolation.
• Monitoring & Observability: Own the monitoring stack to proactively identify issues before they impact users. Come to the table with recommendations for cost-saving and performance improvements.
• Leadership & Proactivity: Act as a self-driven expert who doesn''t wait for a ticket to fix a problem. You will mentor junior staff and drive the technical roadmap for our infrastructure.

Required Skills & Experience

• Terraform (Required): 3+ years writing production Terraform. Must be comfortable with modules, workspaces, remote state, and provider version pinning. Experience with Terragrunt is a strong plus.
• AWS (Required): 4+ years of hands-on AWS experience. Must have deep knowledge of VPC, IAM, EC2, ECS/EKS, Lambda, S3, RDS/Aurora, CloudWatch, and CloudTrail. AWS Solutions Architect or DevOps Engineer certification preferred.
• CI/CD & GitOps: Practical experience integrating Terraform into CI/CD pipelines (GitHub Actions, Jenkins, or GitLab CI). Familiarity with plan/apply workflows, drift detection, and policy-as-code tools like Sentinel or OPA.
• Containers & Orchestration: Working knowledge of Docker and Kubernetes (EKS preferred). Ability to provision and manage EKS clusters through Terraform. DevOps tooling experience (Helm, ArgoCD) is a plus but not the primary focus.
• Scripting & Automation: Proficiency in Python or Bash for infrastructure automation tasks, Lambda functions, and custom resource provisioning.
• Nice to Have: AWS CDK or CloudFormation exposure, experience with multi-account AWS Organizations setups (Control Tower / Landing Zone), and familiarity with FinOps or cost allocation tagging strategies.
