Senior DevSecOps Engineer

Company Overview

Pantheon Data (a Kenific Holding company) is a private, small business based in the Washington, DC, area. Pantheon Data was founded in 2011, initially providing acquisition and supply chain management services to the US Coast Guard. Our service offerings have grown in the past ten years, including infrastructure resiliency, contact center operations, information technology, software engineering, program management, strategic communications, engineering, and cybersecurity. We have also grown our customer base to include commercial clients. The company has used this experience to expand our service offerings to other agencies within the Department of Homeland Security (DHS), the Department of Defense (DoD), and other Federal Civilian Agencies.

Position Overview

Pantheon Data is seeking a Senior DevSecOps Engineer to design, build, and operate the secure software delivery platform for ML-enabled workloads and applications in AWS GovCloud that process CUI, PII, and PHI. GitLab Ultimate is our DevSecOps platform: you will own our GitLab CI/CD architecture end to end - pipelines, runners, security scanning, policy enforcement, and compliance evidence - and lead the migration of existing repositories and pipelines onto it.

The role combines secure pipeline engineering with production Amazon EKS delivery through GitOps, enforcing gated security controls that satisfy NIST 800-53, FedRAMP, and DoD SRG requirements while keeping delivery fast. You will partner closely with the Cloud Operations Engineer, who builds and runs the underlying AWS infrastructure, and the Cloud Security Engineer, who owns cloud security controls and ATO evidence. Successful candidates can walk through pipelines and platforms they have personally built - stage design, security gates, runner architecture, failure modes, and the compliance evidence they produced.

Responsibilities

• GitLab CI/CD Engineering: Design, implement, and operate enterprise-grade GitLab CI/CD pipelines, including multi-project/parent-child pipeline orchestration, environment promotion gates, protected branches and environments, and reusable pipeline templates and CI components.
• GitLab Ultimate Security Suite: Deploy, configure, and tune the full GitLab Ultimate security suite as required pipeline gates: Advanced SAST, DAST, secret detection (including push protection), dependency scanning, container scanning, IaC scanning, license compliance, and API security - with findings triaged through the vulnerability management dashboard and merge request security widgets.
• Policy-as-Code & Compliance Automation: Enforce security centrally using scan execution policies, merge request approval policies, compliance frameworks, and compliance pipelines so scanning is mandatory across all projects; provide pipeline and supply chain audit evidence to the Cloud Security Engineer for ATO, POA&M, and continuous-monitoring activities.
• Software Supply Chain Security: Generate and manage SBOMs, enforce dependency and license policies, sign and verify build artifacts and container images, and maintain a secure, traceable path from commit to production.
• Runners & Cloud Auth: Architect and operate GitLab Runner fleets in GovCloud (autoscaling, isolation, hardened images) and work with the Cloud Operations and Cloud Security Engineers to implement keyless OIDC authentication from GitLab to AWS IAM roles - no long-lived cloud credentials in CI.
• Kubernetes & GitOps: Manage lifecycle, networking, and security for production Amazon EKS clusters; orchestrate deployments with Helm and GitOps tooling (Argo CD or Flux) for declarative state management; harden registries, and OCI image workflows.
• 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 the Cloud Security Engineer on control implementation and assessment support.

Required Skills and Experience

• Bachelor's degree in Computer Science, Information Technology, Information Systems, Engineering, or a related technical field, from an accredited university.
• 5+ years in DevSecOps/DevOps engineering with responsibility for production AWS environments.
• Deep, hands-on CI/CD expertise with GitLab CI/CD, GitHub Actions, or a comparable platform: pipeline design at scale, integrated security scanning (SAST/DAST/secret detection/dependency/container/IaC), policy-enforced approvals, and 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 the infrastructure behind pipelines, runners, and clusters: modular design, state management, and multi-environment promotion.
• Working understanding of security compliance frameworks and how they translate into technical controls and pipeline security gates in cloud environments.
• 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; meet deadlines; and produce quality work with clear written communication.
• Proficient in Microsoft Suite software including Outlook, Word, Excel, SharePoint, and PowerPoint.

Preferred Skills and Experience

• 10+ years of overall experience in technology and software engineering, demonstrating senior-level breadth beyond DevSecOps.
• Direct experience with GitLab Ultimate security and compliance features: scan execution and merge request approval policies, compliance frameworks, vulnerability management and security dashboards, and GitLab Runner administration.
• Experience administering self-managed GitLab (or GitLab Dedicated for Government) in GovCloud or another isolated/restricted-egress environment, including upgrades, backups, and instance hardening.
• Experience migrating organizations from GitHub/GitHub Actions (including GitHub Advanced Security) to GitLab Ultimate.
• Experience delivering software in FedRAMP High or DoD IL4/IL5 environments, including STIG- and CIS-compliant container images and pipeline controls mapped to NIST SP 800-53.
• Supply-chain security depth: SLSA, Sigstore/cosign artifact signing, SBOM management, and dependency provenance.
• Experience supporting ML/AI platforms (model serving, GPU workloads, Amazon Bedrock integrations, or data pipelines) in regulated environments.
• CI/CD and application secrets management with AWS Secrets Manager or HashiCorp Vault; policy-as-code tools such as OPA/Kyverno; and admission control for Kubernetes.
• Additional AWS certifications such as Solutions Architect or SysOps Administrator; Kubernetes certifications (CKA/CKS).
