Senior Devops with AWS - Contractor

Senior AWS DevOps Engineer – 6‑month transformation initiative focused on simplifying an AWS network environment, improving security, maintainability, and scalability. The project involves designing a streamlined architecture with a reduced number of subnets and controlled connectivity, followed by a phased migration of services.

Responsibilities

• Implement and maintain target infrastructure through Terraform and automation tooling, translating the target architecture into reusable, version‑controlled IaC in close collaboration with the Solution Architect and Network Engineer.
• Maintain and adapt CI/CD pipelines required for infrastructure and application deployment, including setup and support of a parallel test environment with Concourse pipelines alongside the existing Jenkins setup.
• Coordinate deployment and migration activities with internal teams and third parties, helping resolve technical dependencies and ensuring service level objectives are maintained throughout the transition.
• Monitor and validate migrated services, including API connectivity checks with tools such as Postman.
• Contribute to continuous improvement of deployment processes, tooling and operational practices used across the cloud environment.

Qualifications

• 5+ years of experience as an AWS DevOps Engineer.
• Strong hands‑on AWS experience in deploying and monitoring production containerised services.
• Strong experience with Terraform‑based infrastructure as code (IaC), including supporting migration from selected CloudFormation templates to Terraform where required.
• Working knowledge of AWS networking: VPCs, subnets, routing and security groups.
• Experience with serverless and container deployments (Lambda, Docker, ECS).
• Experience using scripts to automate the configuration of services and tools via their APIs or SDKs with a background using Python and other tools (e.g. PowerShell, Bash, Shell).
• Experience developing in a source‑controlled workspace (GitHub/Bitbucket).
• Experience with CI/CD pipelines, including Jenkins and Concourse.
• Experience in deploying and managing deployments of relational databases such as MS SQL, MySQL and Postgres.
• Understanding of the software engineering lifecycle, including design, architecture, test automation, deployment automation, monitoring and alerting.
