• Design PostgreSQL/Aurora schemas, optimize queries, manage migrations and perform data loading.
• Deploy, troubleshoot and maintain applications across AWS classified partitions and regions.
• Work with AWS services including EKS, Aurora, S3, IAM, VPC and KMS.
• Develop and maintain reusable Terraform modules and infrastructure-as-code.
• Integrate secure authentication and authorization using Keycloak, OIDC, SAML and/or CAC/PIV.
• Develop secure applications in STIG-hardened and FIPS-validated environments.
• Build and maintain GitLab CI/CD pipelines and follow established Git workflows.
• Troubleshoot DevSecOps issues and support secure application deployments.
• Contribute to legacy data migration, platform enhancements, pilot applications and custom MVP development.
• Utilize appropriate AI-assisted development tools to improve development productivity while maintaining security and code-quality standards.

Required Qualifications

• Active TS/SCI clearance.
• 5+ years of hands-on software development experience.
• Strong production experience developing Python backends using Django and/or FastAPI.
• Experience with async/ASGI and modern Python 3.13+ development.
• Demonstrated production experience building complete applications with React, Next.js or an equivalent frontend framework.
• Strong understanding of RESTful API design and Backend-for-Frontend patterns.

• Experience with EKS, Aurora, S3, IAM, VPC and KMS.
• Experience developing and maintaining Terraform modules.
• Experience integrating authentication using Keycloak, OIDC, SAML and/or CAC/PIV.

• Experience working in STIG-hardened and FIPS-validated environments.
• Experience with GitLab CI/CD and Git-based development workflows.
• Strong troubleshooting and problem-solving skills.

Candidate Profile The ideal candidate is a true full-stack engineer, not primarily a backend developer. Candidates must be able to demonstrate hands-on experience developing and supporting both Python backend services and production frontend applications.

Experience with secure cloud environments, DevSecOps, infrastructure-as-code and classified AWS deployments is highly valued.
