orchestrate deployments with Helm and GitOps tooling (Argo CD or Flux) for declarative state management; harden clusters, registries, and OCI image workflows. ML Workload Support: Deploy and scale containerized ML models and data pipelines; build observability (metrics, logging, alerting, tracing) for regulated, restricted-egress environments. Platform Migration: Lead the migration of repositories, pipelines, and integrations from GitHub/GitHub Actions to GitLab, including translation of workflows, secrets strategy, branch protection parity, and developer enablement. Team Enablement: Mentor engineers on secure delivery practices, author runbooks and pipeline documentation, and partner with security and compliance teams on control implementation and assessment support. Required Skills and ExperienceBachelor's degree in Computer Science, Information Technology, Information Systems, Engineering, or a related technical field, from an ABET accredited university. 5+ years in DevSecOps/DevOps engineering with responsibility for production AWS environments. Plus an additional 5 years of experience in a related technical field.  Deep, hands-on GitLab expertise: GitLab CI/CD pipeline design at scale, GitLab Ultimate security and compliance features (SAST/DAST/secret detection/dependency/container/IaC scanning, scan execution and approval policies, security dashboards), and GitLab Runner administration. Experience implementing gated DevSecOps controls in CI/CD - pipelines that block on security findings, enforce approvals, and produce auditable evidence. Deep hands-on expertise with Amazon EKS: cluster hardening, OCI-compliant image management, Helm, and GitOps deployment patterns (Argo CD or Flux). Proficiency in Terraform for complex networking and security stacks: modular design, state management, and multi-environment promotion. Practical understanding of NIST SP 800-53, FedRAMP, and DoD RMF/SRG, and their application to technical configurations in AWS GovCloud (STIGs, CIS benchmarks, boundary controls, audit logging). Scripting proficiency in Python or Bash for operational automation and security tooling. Current AWS Certified DevOps Engineer – Professional or AWS Certified Security – Specialty. Ability to work effectively in remote, cross-functional teams;
