About The Position

The Cloud System Engineer III is a senior, hands-on cloud engineer responsible for designing, building, securing, and optimizing CI/CD capabilities in an AWS environment. The role combines AWS engineering with Git, GitLab CI/CD, automation, and DevSecOps expertise to create secure, scalable, and reliable delivery platforms that help engineering teams build, test, and deploy applications into AWS consistently. The engineer provides technical leadership for AWS-based DevSecOps and GitLab CI/CD engineering. The role includes architecting reusable delivery pipelines, managing GitLab runners and repository workflows, automating infrastructure and application deployments, integrating security controls into software delivery, troubleshooting complex cloud and deployment issues, and helping teams adopt consistent cloud-native development practices. This is a remote work arrangement. The role requires the ability to obtain and maintain a U.S. Government security clearance.
