The Opportunity

We're looking for a Senior Platform Engineer (AWS) to play a key role in the delivery of a major API infrastructure transformation project. You'll work closely with platform architects, engineers, and SREs to design, build, and migrate key services to a modern API management platform - supporting both the pilot phase and full migration from a legacy EC2-based setup.

This is a hands-on, project-focused role (circa 85% delivery), ideal for a senior engineer with deep AWS experience and a strong DevOps mindset.

Key Responsibilities

• Build and deploy infrastructure for a new API management platform (supplier selection in progress).
• Lead the migration of APIs from an existing EC2-based environment to a container-based architecture.
• Deploy and support the ACS (API Control System) platform.
• Write and maintain infrastructure as code using Terraform.
• Set up and manage CI/CD pipelines using GitLab.
• Support initial pilot migrations and help define repeatable deployment patterns.
• Collaborate with SREs, platform engineers, and architects to ensure smooth delivery.
• Provide hands-on expertise in Kong API Gateway migration.
• Contribute to observability using Datadog.
• Use Jira, Confluence, and SonarQube for tracking, documentation, and quality control.

Required Skills & Experience

• 7+ years' experience as a DevOps or Platform Engineer, with deep knowledge of AWS.
• Strong background in infrastructure automation and Infrastructure as Code - especially Terraform.
• Proven ability to work with GitLab CI/CD for build and release pipelines.
• Experience with containerised applications and modern cloud architectures.
• Familiarity with deploying ACS platforms.
• Understanding of observability tools - Datadog preferred.
• Comfortable in collaborative, agile teams, with strong documentation and delivery discipline.

If you're a highly skilled AWS engineer looking to lead on a cutting-edge API migration project, we'd love to hear from you.
