Senior AWS DevOps / Cloud Engineer – Production Cutover + Long-Term Part-Time Support

# Senior AWS DevOps / Cloud Engineer – Production Cutover + Long-Term Part-Time Support We are looking for an experienced **AWS DevOps / Cloud Engineer** to assist our development team with the final stages of a production migration and cutover, followed by a potential long-term part-time support relationship. Our new AWS infrastructure has **already been designed, built, documented and tested by an AWS consultancy**. A significant part of the migration has also already been completed. We are therefore **not looking for someone to redesign our AWS architecture or perform a large infrastructure audit**. The immediate requirement is for a senior AWS engineer who can quickly familiarise themselves with the existing environment, assist with the remaining migration/cutover tasks, and provide experienced AWS support during the production switch in case any infrastructure issue or rollback is required. ## Existing AWS Environment The infrastructure is hosted in **AWS eu-west-1 (Ireland)** and is primarily managed through Terraform. It includes: - EC2 application servers - EC2 Auto Scaling Groups and Launch Templates - Application Load Balancer - CloudFront - AWS WAF - RDS MySQL / MariaDB - EFS shared storage - Secrets Manager - EventBridge / Systems Manager - CloudWatch alarms and dashboards - SNS notifications - GitHub Actions - AWS CodeDeploy - IAM/OIDC - Nginx - PHP / PHP-FPM - Cloudflare DNS The architecture and operational processes are documented, and the Terraform repository and production cutover documentation are available. The architecture is EC2-based and is not based on ECS, Kubernetes or containerisation. ## Immediate Requirement Our development team is already carrying out the migration and much of the work has been completed. We primarily need an experienced AWS engineer to: - Quickly review the existing architecture, Terraform configuration and relevant documentation so you understand the environment. - Work alongside our developer on the remaining infrastructure-related migration issues. - Help verify that the new production environment is correctly configured before cutover. - Assist with any remaining AWS, EC2, Auto Scaling, Load Balancer, RDS, EFS, Nginx, deployment or networking issues encountered during the migration. - Review the final production cutover sequence. - Be available during the final cutover to troubleshoot any AWS/infrastructure issue that occurs. - Help us execute a rollback safely if the new environment experiences a serious issue after cutover. - Verify infrastructure health immediately following migration. We do **not** expect a lengthy infrastructure discovery or redesign phase. The environment has recently been professionally built and documented. The objective of the initial review is simply to allow you to become familiar enough with the infrastructure to support the migration safely. ## Long-Term Relationship If the initial engagement works well, we would like this person to become our ongoing AWS/DevOps contact. Our development team manages the application internally, so this would not be a full-time or high-volume role. We would expect occasional assistance with: - AWS infrastructure problems - Deployment failures - Auto Scaling / EC2 issues - RDS or database infrastructure issues - Terraform changes - CloudWatch alerts - AWS cost anomalies - Security or infrastructure configuration questions - Future infrastructure changes or migrations We would also like to carry out a short periodic infrastructure health check to confirm that everything remains correctly configured. Our preference initially is an **hourly relationship rather than a large monthly retainer**. If the relationship develops and a small monthly support arrangement makes sense later, we are open to discussing it. ## Experience Required We are looking specifically for someone with strong production experience in: - AWS EC2 - Auto Scaling Groups and Launch Templates - Terraform - Application Load Balancers - RDS MySQL / MariaDB - EFS - CloudFront / WAF - CloudWatch - IAM / Secrets Manager - GitHub Actions - AWS CodeDeploy - Linux / Nginx / PHP-FPM - Production migrations and cutovers - Rollback and disaster-recovery procedures - Cloudflare / DNS ## Strong References Required We are looking for someone who has done this repeatedly in real production environments. Please include: 1. Examples of similar AWS production environments you have personally managed. 2. Examples of production migrations or cutovers you have personally completed. 3. An example of an AWS production incident you diagnosed and resolved. 4. Your experience with Terraform + EC2 Auto Scaling environments. 5. Previous client references or Upwork projects demonstrating this experience. 6. AWS certifications, if applicable. 7. Your timezone and normal availability. 8. Your hourly rate. 9. Your availability for occasional urgent infrastructure support after the migration. Please start your proposal with: **VINTRAIL AWS** and briefly explain what you would check before supporting a production cutover on an existing Terraform-managed EC2 Auto Scaling environment. Generic proposals will not be considered.
