Senior DevSecOps Engineer

IntelliTech is a dynamic and forward-thinking small business specializing in Full Stack Engineering, Data Analytics, Cloud Solutions, and DevSecOps services. They are seeking a Senior DevSecOps Engineer to lead the infrastructure modernization and security hardening of a Government-owned digital twin application deployed in an Army cloud environment. This hands-on role involves architecting deployment infrastructure, building CI/CD pipelines, and ensuring the application is secure and ready for operational use.

Responsibilities:

• Transition the application from a single-host Docker deployment to a split-service containerized architecture using Amazon EKS, ECS, or another approved orchestration model
• Design and implement multi-tier environment separation across development, test/staging, and production
• Package frontend, backend API, and simulation worker services as independently deployable container artifacts
• Implement infrastructure-as-code using Terraform, CloudFormation, or approved equivalents for repeatable provisioning and configuration management
• Design the distributed execution model allowing simulation workers to scale independently from the API tier with bounded concurrency and isolation controls
• Configure managed platform services for persistence, caching, object storage, secrets management, and observability
• Build and maintain CI/CD pipelines using approved toolchains such as GitLab CI, GitHub Actions, or government-provided platform tooling
• Integrate automated build, test, container scanning, dependency scanning, SAST, and DAST into the delivery pipeline
• Implement promotion workflows with quality and security gates for development-to-staging and staging-to-production transitions
• Generate and maintain software bill of materials (SBOM) and dependency inventories as part of the build process
• Design rollback and recovery procedures for failed deployments, including restoration of prior known-good versions
• Harden container images and dependency baselines in alignment with STIG requirements and approved security standards
• Implement managed secrets storage, encryption in transit and at rest, least-privilege IAM policies, and appropriate network segmentation
• Integrate vulnerability scanning into release workflows and support remediation tracking
• Support closure of security findings through remediation, compensating controls, and evidence updates
• Ensure artifact retention and traceability sufficient to support promotion approval and auditability
• Integrate the application with CAC-enabled SSO and the identity provider required by the target environment using SAML, OIDC, or platform-specific approaches
• Replace local account models with externalized authentication through approved identity services
• Implement role-based access controls for analyst, administrator, and system functions
• Ensure user actions are traceable to authenticated identities
• Support the application-specific authorization effort from evidence planning through submission and remediation
• Produce and maintain authorization artifacts such as architecture diagrams, data flows, SBOMs, scan evidence, logging and monitoring descriptions, and operational runbooks
• Align evidence to the platform’s inheritance model where applicable rather than building a fully standalone compliance package
• Coordinate with government security stakeholders on evidence expectations, findings, and remediation
• Lead technical execution for promotion from development into production through approved DevSecOps pipelines and release gates
• Implement centralized logging, metrics, alarms, and service health monitoring across all application components
• Develop operational runbooks for deployment, monitoring, incident response, scaling, and maintenance
• Produce administrator and operator documentation, troubleshooting guides, and sustainment handoff materials
• Support training and transition activities at the conclusion of the implementation period

Requirements:

• Bachelor's degree in Computer Science, Information Systems, Engineering, Cybersecurity, or a related technical discipline and 8+ years of relevant experience; or Master's degree in a related field and 6+ years of relevant experience
• Active DoD Secret clearance
• 8+ years of professional experience in DevOps, platform engineering, infrastructure engineering, or cloud engineering roles
• Hands-on experience supporting ATO or cATO-related processes, including authorization evidence development, security findings remediation, and working with assessors or platform security stakeholders
• Experience deploying and operating applications in DoD or other accredited government cloud environments such as Army ECMA
• Strong experience with container orchestration using Amazon EKS, ECS, Kubernetes, or similar platforms
• Strong experience with infrastructure as code, including Terraform, CloudFormation, Helm, or similar tooling
• Experience designing and maintaining CI/CD pipelines with integrated automated testing, scanning, and promotion controls
• Experience with security hardening, including STIG-aligned practices, vulnerability remediation, SBOM generation, and secure container/image management
• Experience with AWS services such as EC2, EKS/ECS, S3, IAM, KMS, Secrets Manager, SSM, CloudWatch, VPC/networking, Redis/ElastiCache, and document or relational persistence services
• Experience integrating identity and access management solutions such as SSO, SAML, OIDC, RBAC, or CAC-enabled access patterns
• Strong communication skills and the ability to work directly with technical, operational, and security stakeholders
• Direct experience supporting Army cloud environments or similar government-managed enterprise cloud platforms
• Experience with RMF, eMASS, and inherited authorization models
• Experience operating in IL4 / IL5 or similarly regulated environments
• Experience with container security and vulnerability scanning tools such as Prisma Cloud, Anchore, Twistlock, or similar platforms
• Familiarity with Docker Compose to Kubernetes migration patterns
• Experience with MongoDB to DocumentDB migration or similar managed database transition efforts
• Experience supporting Python / FastAPI application deployment and performance tuning
• Prior experience supporting Army, logistics, manufacturing, industrial base, or enterprise platform modernization programs
• Certifications such as Security+, CISSP, or relevant cloud / Kubernetes certifications
