## About the Role

* US Citizen
 * Ability to obtain a DoW (formerly DoD) Active Secret clearance
 * Experience: 6+ years in DevOps, DevSecOps, SRE, or platform engineering roles supporting production cloud applications (or equivalent depth with clear ownership of CI/CD + cloud infrastructure).
 * Cloud & IaC: Hands-on experience designing and operating AWS workloads with Terraform (multi-env var files, remote state, modules, and safe plan/apply workflows).
 * Containers & compute: Experience deploying and operating containerized services on ECS (or EKS/Kubernetes with clear transferability), including task/service definitions, autoscaling, and rollout practices.
 * CI/CD: Strong experience building and maintaining pipelines in GitLab CI (or similar) for infrastructure and application delivery, including secrets, OIDC/role assumption, and environment-based promotion.
 * Security: Practical DevSecOps mindset-IAM least privilege, secure pipeline design, secret management, and hardening of build/deploy paths.
 * Collaboration: Ability to work closely with application teams (Node.js/React and backend services), translate operational requirements into automation, and communicate clearly in design reviews and MR feedback.
 * Troubleshooting: Proven ability to debug failed pipelines, Terraform drift/apply errors, and AWS runtime issues under time pressure.

Nice to Have:

 * Experience with AWS GovCloud and/or DoD / Cloud One / IL4-IL6 style environments and controls.
 * Experience with API gateways (e.g. Tyk or equivalents), ICAM / AuthN / AuthZ platforms (e.g. Keycloak), and policy engines (e.g. OPA).
 * Experience with FinOps / cost-control automation (scheduled scale-to-zero, start/stop of RDS/ECS, environment inventories).
 * Experience with Docker image build, lightening/hardening, and ECR (or equivalent registries).
 * Experience with Systems Manager, EventBridge/scheduling patterns, and App Auto Scaling for ECS.
 * Experience with SonarQube or other automated quality/security scanning in CI.
 * Experience with environment factories/bootstrap modules that provision accounts or shared platform baselines.
 * Ability to obtain U.S. Security Clearance.

## Description

* Own and evolve infrastructure-as-code, CI/CD, and cloud deployment patterns for the DME / ACDC platform application stacks (Node.js/React dashboard, API gateway, identity, and policy services).
 * Design, implement, and maintain Terraform modules and environment pipelines that provision and operate AWS workloads (ECS, RDS, IAM, networking, and supporting services) across multiple non-prod and production-like environments.
 * Build and harden GitLab CI/CD workflows for plan/apply, image build/push, and controlled deployments, including runner configuration, credentials/role assumption, and environment promotion practices.
 * Partner with application engineers to make services operable in AWS: ECS task definitions, autoscaling, service lifecycle, secrets/config, logging/metrics, and safe restart/redeploy patterns.
 * Drive platform reliability and cost efficiency through automation (for example, environment park/wake schedules, inventory-driven start/stop tooling, and guardrails that prevent unsafe operations on protected environments).
 * Embed security into delivery: least-privilege IAM, permissions boundaries, secure defaults for containers and pipelines, secret handling, and compliance-minded patterns for GovCloud / elevated environments.
 * Lead incident and change support for infrastructure and pipeline failures-diagnose Terraform/state, CI, and AWS runtime issues, and land durable fixes.
 * Improve engineering maturity through reusable modules, documented runbooks, reviewable IaC standards, and mentorship of developers on DevOps/DevSecOps practices.
 * Review merge requests for infrastructure, CI, and deployment changes; uphold quality, security, and operational readiness before merge.
