Job summary

Modern Technology Solutions, Inc. (MTSI) seeks an experienced AWS Government Cloud Architect Engineer to own the design and implementation of a new AWS government cloud environment in Huntsville, AL.

This greenfield buildout requires hands‑on execution, from foundation to operational readiness, with emphasis on secure architecture and auditable controls. The role demands deep AWS services, IaC (Terraform, CloudFormation, CDK), and alignment with NIST SP 800‑171; citizenship and ability to obtain

Qualifications

• Bachelor’s degree in Computer Science, Information Technology, Engineering, or a related field, or equivalent relevant professional experience.
• Minimum 9 years of relevant experience designing, implementing, and supporting AWS cloud infrastructure, or equivalent qualifying experience.
• Hands-on experience designing, building, securing, and operating AWS government cloud environments. Commercial AWS experience alone does not satisfy this requirement.
• Experience taking a greenfield cloud environment, landing zone, or shared‑services platform from architecture through implementation and operational readiness.
• Demonstrated hands‑on experience implementing technical controls aligned with NIST SP 800‑171 for environments intended to protect CUI.
• Experience translating compliance requirements into cloud architecture, AWS configurations, Infrastructure as Code, monitoring, operational procedures, remediation, and assessment evidence.
• Ability to work independently, resolve ambiguity, and own technical outcomes in a deliberately phased environment.

Responsibilities

• Own the hands‑on architecture and implementation of a new AWS government cloud environment from initial foundation through operational readiness.
• Build and configure AWS account structures, networking, identity and access management, security services, encryption, logging, monitoring, backup, recovery, and shared platform capabilities.
• Develop and maintain Infrastructure as Code using Terraform, AWS CloudFormation, AWS CDK, or comparable technologies.
• Translate applicable NIST SP 800‑171 requirements into implemented, tested, documented, and maintainable AWS technical controls for the protection of CUI.
• Define and document system boundaries, approved data flows, network segmentation, access paths, shared responsibilities, and inherited controls.
• Implement least privilege, privileged‑access protections, multifactor authentication, secure configuration baselines, audit logging, continuous monitoring, and configuration‑drift controls.
• Contribute technical content and evidence for the System Security Plan (SSP), control implementation statements, Plans of Action and Milestones (POA&Ms), architecture diagrams, data‑flow diagrams, asset inventories, and assessment‑readiness activities.
• Identify technical control gaps, implement remediation, validate corrective actions, and support authorized compliance assessments.
• Build automation and CI/CD capabilities that improve security, consistency, repeatability, and operational support.
• Troubleshoot complex cloud infrastructure, networking, identity, security, automation, and integration issues.
• Create architecture diagrams, implementation records, operating procedures, and technical decision documentation.
• Maintain forward progress through documentation, automation, testing, design refinement, and risk reduction when implementation dependencies slow deployment activity.
• Coordinate with security, compliance, networking, DevSecOps, engineering, and operations stakeholders while retaining technical ownership of the AWS implementation.
