About The Position

pureIntegration is seeking a Cloud Solutions Engineer to support a large-scale migration of a consumer email platform from legacy on-premises datacenters onto a new AWS-hosted platform. This engagement involves approximately 2.38 million mailboxes, 2.2 PB of message data, and 23.5 billion messages moving onto an EKS/EC2-based architecture, with a target completion of Q1 2027. The role operates within an established, AI-assisted Terraform codebase and a disciplined engineering environment, emphasizing 100% infrastructure as code, pipeline-only deployments, and mandatory Architecture Decision Records (ADRs) for any deviation from established patterns.

Requirements

3–5+ years of hands-on AWS infrastructure engineering, with demonstrated production-level Terraform experience.
Proven ability to work from existing specifications, ADRs, and code with minimal oversight.
GitLab CI/CD (or equivalent) experience, including debugging existing pipelines.
Python proficiency, used as the personal default language.
Willingness and ability to work on-site with the Principal Engineer and mail platform team.
Comfort working in an AI-assisted codebase, with the judgment to review and correct AI-generated work rather than extend it uncritically.

Nice To Haves

Production-level Terraform (HCL)
GitLab CI/CD pipeline design and debugging, including multi-environment pipelines, component versioning, and runner configuration.
AWS (EKS, EC2/ASG, IAM, Route53)
Sufficient Ansible proficiency to evaluate and troubleshoot vendor-delivered playbooks.

Responsibilities

Validate Terraform components and pipelines end to end in development, then promote through UAT and production, resolving defects rather than treating a clean plan as complete.
Onboard new AWS accounts, components, and infrastructure into the existing pipeline pattern as the build-out continues.
Review, integrate, and troubleshoot the platform vendor's Ansible playbooks and migration tooling, raising concerns rather than implementing without question.
Operate within the existing Terraform/GitLab CI/CD pattern; propose new tooling choices via ADR.
