Job description

The remoteCloud System Engineer III – AWS DevSecOps & GitLab CI/CD will serve as a senior, hands‑on cloud engineer responsible for designing, building, securing, and optimizing CI/CD capabilities within a modern AWS environment in a remote work arrangement.

This role combines deep AWS engineering expertise with advanced Git, GitLab CI/CD, automation, and DevSecOps experience. The successful candidate will architect reusable delivery pipelines, manage GitLab runners and repository workflows, automate cloud deployments, integrate security controls into the software delivery lifecycle, and help engineering teams adopt consistent cloud‑native development practices.

The ideal candidate is not simply a CI/CD administrator. You should be comfortable working deeply within AWS, troubleshooting cloud infrastructure and deployment issues, designing secure delivery patterns, and using Git and GitLab as core components of enterprise software engineering.

Success in this role means creating secure, scalable, and reliable delivery platforms that allow engineering teams to build, test, and deploy applications into AWS quickly and consistently while maintaining strong security, governance, and operational standards.

What You Will Do in This Role

The Cloud System Engineer III will provide senior technical leadership for AWS‑based DevSecOps and GitLab CI/CD engineering, supporting secure application development and automated cloud deployment.

Responsibilities include:

• Architect, build, maintain, and optimize enterprise GitLab CI/CD pipelines supporting application build, testing, security validation, and deployment into AWS.
• Serve as a senior technical resource for AWS cloud engineering, CI/CD architecture, GitLab, Git workflows, and automated deployment practices.
• Design standardized, reusable GitLab pipeline templates, modules, and deployment patterns that can be adopted across multiple applications and engineering teams.
• Configure, manage, scale, and troubleshoot GitLab runners and supporting infrastructure.
• Design and maintain Git‑based software‑development workflows, including repository structure, branching strategies, merge requests, code‑review practices, protected branches, and release processes.
• Integrate GitLab CI/CD with AWS services such as EC2, ECS, EKS, Lambda, S3, IAM, and related cloud services.
• Design secure AWS deployment architectures incorporating IAM, networking, access controls, secrets management, and cloud security best practices.
• Automate cloud infrastructure and application deployments using Terraform, AWS CloudFormation, or comparable Infrastructure as Code technologies.
• Implement automated testing, quality gates, security scanning, vulnerability detection, artifact management, and other DevSecOps controls throughout the CI/CD lifecycle.
• Support containerized application deployments using Docker, Kubernetes, Amazon ECS, and/or Amazon EKS.
• Troubleshoot complex AWS, GitLab, Git, pipeline, runner, infrastructure, networking, IAM, and application deployment issues.
• Identify performance bottlenecks and reliability issues within pipelines and cloud deployment workflows and implement improvements.
• Partner with developers, cloud engineers, security teams, architects, and other stakeholders to establish scalable engineering and deployment standards.
• Provide technical guidance and mentorship to engineering teams using GitLab, Git, AWS, Infrastructure as Code, and modern DevSecOps practices.
• Establish technical standards, documentation, operational procedures, and reusable engineering patterns.
• Evaluate technical requirements, identify risks, and recommend appropriate AWS architecture and deployment approaches.
• Develop tools and automation that improve developer productivity, deployment reliability, security, and operational consistency.
• Support continuous improvement of AWS cloud architecture, CI/CD tooling, Git workflows, and software delivery practices.
• Perform other duties and responsibilities as assigned.

Required Qualifications

• Bachelor's degree in Systems Engineering, Computer Science, Information Technology, or a related technical discipline, or equivalent relevant professional experience.
• Senior‑level, hands‑on experience engineering and supporting production workloads within AWS.
• 6+ years of demonstrated hands‑on experience with GitLab CI/CD, including pipelines, runners, GitLab configuration, and deployment automation.
• Advanced hands‑on experience with Git, including branching strategies, merge requests, source‑control workflows, repository management, and release processes.
• Demonstrated experience designing and building production CI/CD pipelines used to build, test, secure, and deploy applications.
• Strong experience integrating CI/CD pipelines with AWS environments and services.
• Strong knowledge of AWS services, IAM, networking, security, and secure application deployment patterns.
• Experience with AWS services such as EC2, ECS, EKS, Lambda, S3, IAM, and related cloud technologies.
• Hands‑on experience with Infrastructure as Code using Terraform, AWS CloudFormation, or comparable technologies.
• Experience implementing automated testing, security scanning, quality gates, and other DevSecOps controls within CI/CD pipelines.
• Strong understanding of software‑development lifecycles, version‑control strategies, release management, and cloud‑native deployment practices.
• Experience troubleshooting complex AWS infrastructure, GitLab pipeline, runner, networking, IAM, and deployment issues.
• Ability to design clean, maintainable, reusable CI/CD templates and automation.
• Strong technical communication, documentation, collaboration, and problem‑solving skills.
• Ability to obtain and maintain a U.S. Government security clearance.

Preferred Qualifications

• Experience with Docker and containerized application environments.
• Experience with Kubernetes, Amazon EKS, and/or Amazon ECS.
• Experience implementing DevSecOps practices within regulated or federal cloud environments.
• Experience with SAST, DAST, dependency scanning, container scanning, secrets detection, or other automated security tooling.
• Experience with artifact repositories and software package‑management workflows.
• Experience managing GitLab environments supporting multiple development teams or applications.
• Experience mentoring engineers on Git, GitLab, CI/CD, AWS, and cloud‑native software‑development practices.
• Relevant AWS, GitLab, Kubernetes, or DevOps certifications.
• Experience working within federal government, government contracting, or other highly regulated technology environments.

Work Authorization / Security Clearance Requirements

• Ability to obtain and maintain a security clearance.
