Your tasks

INflow is standing up a GitLab Professional Services practice as a subcontracting partner to GitLab. As a Senior GitLab DevSecOps Engineer, you will deliver GitLab-scoped engagements for GitLab's enterprise and public sector customers, working alongside the GitLab PS team under GitLab's methodology, on GitLab-managed statements of work.

The work is cleared, customer-facing, and runs against defined scopes. You will install and operate GitLab at enterprise scale, migrate agencies off legacy platforms, design CI/CD and DevSecOps pipelines, and roll out GitLab Duo and the Duo Agent Platform (DAP) in environments where the mission depends on getting it right the first time.

• Lead enterprise migrations into GitLab from GitHub, Bitbucket, Jenkins, Azure DevOps, or SVN. Use Congregate and direct transfer. Deploy GitLab reference architectures.
• Design and optimize CI/CD pipelines, including security scanning (SAST, DAST, dependency, container) and compliance framework integration.
• Configure and roll out the GitLab Duo Agent Platform (DAP): build and customize agents and flows, enable AI-assisted development workflows, and advise customers on governance and adoption.
• Deliver customer-facing advisory, clear documentation, and knowledge transfer to agency teams. Lead workshops, cutovers, and secure-environment deployments.
• Operate against defined SOWs with GitLab managing the customer relationship. Scope, estimate, and ship work on schedule.
