Senior AWS Cloud Infrastructure Engineer

About

Tata Elxsi brings together the best technology and user‑centric design expertise to help customers deliver innovative solutions and great consumer experiences. Our integrated Design and Technology teams help enterprises reimagine their products and services – from strategy, consumer research and insights, to service and experience design, technology implementation, integration, launch, and beyond.

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. Provide 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. Mentor junior staff and drive the technical roadmap for our infrastructure.

Required Skills & Experience

• Terraform (Required): 3+ years writing production Terraform. 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. 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.
