DevOps Engineer - Cloud Infrastructure (AWS)

About the Role

We are seeking a proactive and experienced DevOps Engineer to manage and scale our new AWS-based cloud architecture. This role is central to building a secure, fault-tolerant, and highly available environment that supports our Sun, Drive, and Comm platforms. You'll play a critical role in automation, deployment pipelines, monitoring, and cloud cost optimization.

Key Responsibilities

• Design, implement, and manage infrastructure using AWS services across multiple Availability Zones.
• Maintain and scale EC2 Auto Scaling Groups, ALBs, and secure networking layers (VPC, public/private subnets).
• Manage API Gateways, Bastion Hosts, and secure SSH/VPN access for developers and administrators.
• Setup and optimize Aurora SQL Clusters with multi-AZ active-active failover and backup strategies.
• Implement and maintain observability using CloudWatch for centralized logging, metrics, and alarms.
• Enforce infrastructure-as-code practices using Terraform/CloudFormation.
• Configure and maintain CI/CD pipelines (e.g., GitHub Actions, Jenkins, or CodePipeline).
• Ensure backup lifecycle management using S3 tiering and retention policies.
• Collaborate with engineering teams to enable DevSecOps best practices and drive automation.
• Continuously optimize infrastructure for performance, resilience, and cost (e.g., Savings Plans, S3 lifecycle policies).

Must-Have Skills

• Strong hands-on experience with AWS core services: EC2(Linux and Windows), ALB, VPC, S3, Aurora (MySQL/PostgreSQL), CloudWatch, API Gateway, IAM, VPN.
• Deep understanding of multi-AZ, high availability, and auto-healing architectures.
• Experience with CI/CD tools and scripting (Bash, Python, or Shell).
• Working knowledge of networking and cloud security best practices (Security Groups, NACLs, IAM roles).
• Experience with Bastion architecture, Client VPNs, Route 53 and VPC peering.
• Familiarity with backup/restore strategies and monitoring/logging pipelines.

Good-to-Have

• Exposure to containerization (Docker/ECS/EKS) or future readiness for CloudFront/ElastiCache integration.
• Knowledge of cost management strategies on AWS (e.g., billing reports, Trusted Advisor).

Why Join Us?

• Work on a mission-critical mobility platform with a growing user base.
• Be a key part of transforming our legacy systems into a modern, scalable infrastructure.
• Collaborative and fast-paced environment with real ownership.
• Opportunity to drive automation and shape future DevSecOps practices.
