AFMS3 Sr. DevSecOps Engineer

General Dynamics Information Technology is a global technology and professional services company that delivers technology solutions and mission services to every major agency across the U.S. government. They are seeking a Senior DevSecOps Engineer to drive infrastructure-as-code and CI/CD pipeline engineering across their cloud environments, focusing on the design, implementation, and continuous improvement of Terraform-managed infrastructure.

Responsibilities:

• Design, build, and maintain modular, reusable Terraform code for provisioning and managing cloud infrastructure across dev, staging, and production environments
• Implement and enforce Terraform state management, workspace strategy, and module versioning to support multiple teams safely
• Establish and follow IaC best practices: code review standards, automated plan/apply workflows, drift detection, and policy-as-code guardrails
• Identify and remediate technical debt in existing infrastructure code to improve maintainability, security, and cost efficiency
• Collaborate with architecture and security teams to ensure infrastructure design aligns with security baselines and compliance requirements
• Design, build, and continuously improve CI/CD pipelines that automate build, test, security scanning, and deployment of applications and infrastructure changes
• Standardize pipeline patterns across teams/repositories to reduce duplication and increase deployment reliability and speed
• Implement deployment safety mechanisms: automated testing gates, canary/blue-green deployments, rollback automation, and release approvals
• Partner with development teams to identify and remove build/deploy friction, shortening lead time from commit to production
• Monitor pipeline health and performance, proactively resolving bottlenecks and failures
• Participate in on-call rotation and incident response for infrastructure and deployment-related issues; contribute to blameless postmortems and follow-through on action items
• Document infrastructure designs, pipeline architectures, and operational runbooks for team use
• Mentor junior engineers on Terraform and CI/CD best practices as opportunities arise
• Stay current with evolving Terraform, cloud provider, and CI/CD ecosystem capabilities, and bring recommendations back to the team

Requirements:

• Active DoD Secret clearance (or higher) required at time of hire
• 5+ years of DevOps/infrastructure engineering experience
• Deep, hands-on production experience with Terraform for infrastructure-as-code across multi-environment cloud deployments
• Proven experience designing and operating CI/CD pipelines (GitLab CI, Jenkins, CodePipeline, or similar)
• Strong working knowledge of core cloud services (networking, IAM, load balancing, monitoring/logging)
• Experience with version control workflows (Git) and code review practices for infrastructure and pipeline code
• Solid scripting/automation ability (Bash, Python, or similar) to support pipeline and infrastructure tooling
• Strong written and verbal communication skills; able to document and explain technical decisions clearly
• Experience with policy-as-code tools (Sentinel, OPA/Conftest) and Terraform automation platforms (Terraform Cloud/Enterprise)
• Experience with containerized workloads (Docker, ECS, Kubernetes) as pipeline deployment targets
• Familiarity with observability stacks (Prometheus/Grafana, Datadog, CloudWatch) for infrastructure and pipeline monitoring
• Relevant certifications (HashiCorp Terraform Associate, AWS Certified DevOps Engineer, or equivalent)
• Prior experience supporting federal, DoD, including familiarity with STIGs/CIS benchmarks and RMF processes
