AFMS3 Sr. DevSecOps Engineer

Position Summary

We are seeking a Senior DevOps Engineer to drive infrastructure-as-code and CI/CD pipeline engineering across our cloud environments. This role owns the design, implementation, and continuous improvement of Terraform-managed infrastructure and the automated build/test/deploy pipelines that ship it, working closely with development and platform teams to increase deployment velocity, reliability, and security. The ideal candidate is a hands-on engineer who can independently design and deliver infrastructure and pipeline solutions with minimal oversight.

Key Responsibilities

Infrastructure as Code (Terraform)

• 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.

CI/CD Pipeline Engineering

• 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.

General Engineering & Operations

• 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.

Required Qualifications

• Active DoW Secret clearance (or higher) required at time of hire.
• 5+ years of DevOps/infrastructure engineering experience.
• Deep, hands-on production experience with for infrastructure-as-code across multi-environment cloud deployments.
• Proven experience designing and operating (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.

Preferred Qualifications

• 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.
