Note: The job is a remote job and is open to candidates in USA. GDIT is hiring a Senior DevOps Engineer to support its National Institute of Allergy and Infectious Diseases (NIAID) team. The role builds and operates Terraform-managed AWS infrastructure for Windows-based applications, migrates on-premises workloads to AWS, and improves automation, monitoring, security, and deployment practices.

Responsibilities

• Create, modify, and maintain AWS infrastructure and services in Terraform. That means writing new modules and configurations, extending existing ones, and managing state across environments
• Deliver infrastructure changes through GitHub Actions and AWS CodeBuild pipelines, so every change is reviewed in a pull request, planned, and applied the same way every time
• Build and maintain the AWS environment that hosts Windows Server and IIS applications running .NET, including EC2, load balancers, AWS WAF, Route 53, IAM, and TLS certificates, all defined in Terraform
• Migrate on-prem Windows applications into AWS and improve them once they land, including moving applications into containers on Amazon ECS where it makes sense
• Automate routine operational work such as certificate renewal, service account credential rotation, patching, and service restarts, using Terraform, PowerShell, and AWS Systems Manager. Where possible, turn these tasks into self-service options for application owners
• Troubleshoot problems across the application and infrastructure layers (IIS, .NET, networking, and AWS services) and fix the root cause in code rather than by hand
• Build and tune monitoring with Amazon CloudWatch and native AWS observability services, including metrics, logs, alarms, dashboards, and the CloudWatch agent on Windows servers, all defined in Terraform. Set service level objectives and alerts so the team hears about real problems before users do
• Work with the security team to remediate vulnerabilities and apply hardening standards to Windows servers and AWS resources
• Review teammates' Terraform and pipeline changes, share what works, and help shape the team's standards for infrastructure as code and deployments

Skills

• Amazon Relational Database Service (RDS), AWS Web Application Firewall (WAF), Certificate Management, Internet Information Server (IIS) Administration, NIST 800-53

• 3+ years using Terraform to create, modify, and automate AWS infrastructure, including writing modules, safely changing existing configurations, and managing remote state
• Experience building and maintaining CI/CD pipelines that deploy infrastructure changes, using GitHub Actions, AWS CodeBuild, or similar tools, with Git branching and pull request workflows
• Hands-on experience with core AWS services, including EC2, VPC, IAM, S3, Elastic Load Balancing, Route 53, and Systems Manager
• Experience implementing monitoring with Amazon CloudWatch, including metrics, logs, alarms, and dashboards, and collecting Windows and IIS logs and metrics with the CloudWatch agent
• 3+ years supporting Windows Server and IIS environments that host .NET applications, including deployment, configuration, TLS certificates, and troubleshooting
• Strong PowerShell scripting skills, plus working knowledge of Python or Bash
• Ability to work independently on complex problems and to communicate clearly with both technical and non-technical stakeholders
• Must be able to obtain and maintain an NIH Public Trust
• Experience migrating Windows and .NET applications from on-prem infrastructure to AWS
• Experience containerizing applications and running them on Amazon ECS
• Experience with Application and Network Load Balancers, AWS WAF, CloudFront, and Route 53 routing policies
• Experience with AWS Secrets Manager or Parameter Store and AWS Certificate Manager, including automated rotation of credentials and certificates
• Patch and configuration automation using SSM Patch Manager and State Manager, or PowerShell DSC
• Datadog experience, including dashboards, SLO design, and alert tuning
• Experience with additional AWS observability services, such as CloudTrail, EventBridge, AWS X-Ray, or CloudWatch Synthetics
• Familiarity with Amazon RDS for SQL Server from the hosting side, such as connectivity, backups, and migrations
• HashiCorp Terraform Associate, AWS Certified DevOps Engineer - Professional, or AWS Solutions Architect certification
