📋 Description

• Architect, build, and maintain robust GitLab Pipelines for seamless application deployment. • Play a key role in assisting the Platform team with the migration of legacy repositories and workflows from BitBucket to GitLab. • Design, deploy, and manage the infrastructure behind our apps—across AWS GovCloud, edge, and Navy networks using Terraform, Ansible, and GitLab. • Drive containerization efforts for mission-critical applications (NADACS, SPECTR, etc.) and manage Kubernetes. • Develop and maintain Helm Charts for deployments and ensure cluster resilience through automated Kubernetes backups and recovery testing (e.g., Velero). • Engineer automated processes for RHEL image hardening and execute automated STIG checklists. • Integrate continuous, automated security scanning directly into pipelines to maintain Authority to Operate (ATO) status and support ICAM integration. • Establish comprehensive continuous monitoring, alerting, and reporting mechanisms (e.g., Prometheus/Grafana) across the platform. • Oversee cryptographic lifecycles through rigorous secrets management and automated key rotations.

🎯 Requirements

• Active Secret clearance or higher (required) and meet DoD 8570/8140 baseline certifications (e.g., CompTIA Security+ CE). • 5+ years of experience (Mid-to-senior level) functioning as a DevSecOps or Platform Engineer, specifically within DoD, federal, or highly regulated environments. • Significant experience deploying and managing cloud infrastructure using AWS GovCloud and hybrid cloud environments. • Hands-on Kubernetes administration and custom Helm chart development (CKAD or CKA preferred). • Strong background in RHEL system administration and scripting automated system/container hardening. • Advanced proficiency building pipelines natively in GitLab, with experience handling migrations from BitBucket. • An automation-centric approach to eliminate manual toil and a security-first mindset that treats security as a foundational element. • Knowledge of secure identity and access management (ICAM) protocols (SAML, OAuth2, OIDC) and proficiency in at least one language (e.g., Python).
