IntelliTech is seeking a Senior DevSecOps Engineer to lead the infrastructure modernization, security hardening, authorization pathway, and production promotion of a Government-owned digital twin application deployed in an Army cloud environment.

About the Application

The application is a supply chain simulation platform built on Python, FastAPI, React, and MongoDB and currently operates as a monolithic Docker deployment.

Role Description

This role will help transition it into a production-grade, containerized, split-service architecture aligned to Army cloud platform requirements, DevSecOps delivery practices, and production promotion gates.

Key Responsibilities

Infrastructure and Deployment Architecture

• 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.

CI/CD and Release Engineering

• 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.
