About The Position

Modern Technology Solutions, Inc. (MTSI) is hiring a Lead Cloud Platform Engineer to work in Springfield, VA or St. Louis, MO. Qualified candidates must be U.S. citizens with an active TS/SCI clearance and be eligible to obtain a CI Poly. This role is instrumental in building NGA’s EA Digital Twin capability, modeling the future-state enterprise and delivering the unified Digital Engineering environment the IC and DoW have sought for years. You will operate at the strategic level while remaining deeply technical, becoming a critical force multiplier for the Chief Architect and for NGA’s Digital Transformation journey. The position leads the architecture, deployment, and sustainment of the Cloud Native Platform (CNP) powering Model-Based Systems Engineering (MBSE), enterprise data integration, Digital Threads, and future Digital Twin operations. The goal is to build and mature a secure, federated, multi-cloud platform that enables enterprise-scale Digital Engineering workflows, authoritative data synchronization and Zero Trust enforcement across multiple enclaves. This role serves as the technical authority for NGA’s CNP, responsible for designing, hardening, deploying and operating the hybrid, multi-cloud platform foundational to the DEE. It integrates cloud native infrastructure, Kubernetes orchestration, identity and access services, telemetry pipelines, DevSecOps automation and platform governance to support enterprise modeling, data fabric and Digital Thread execution. The Lead Cloud Platform Engineer will lead a small but highly skilled team of cloud/platform engineers and collaborate tightly with MBSE leads, data engineers, cyber, enterprise architects and mission area stakeholders to deliver a secure, scalable and resilient DEE platform.

• Experience integrating platform capabilities with enterprise data fabrics, Digital Threads or MBSE environments.
• Experience collaborating with data engineers, MBSE teams, and enterprise architects and Agile/Scrum experience.
• Background supporting DevSecOps in DoD, IC or large-scale engineering ecosystems.
• Strong ability to guide roadmap development, platform governance and enterprise onboarding processes.

Responsibilities

• Own the design, implementation, and evolution of the Cloud Native Platform (CNP), enabling secure, scalable, multi-cloud operations across AWS, Azure, on-prem, and classified enclaves.
• Deploy, harden, and operate Kubernetes environments, service mesh, GitOps and OTEL stacks to ensure reliable, governed platform execution.
• Implement and manage identity federation, enforce Zero Trust policies, manage secrets, certificates, hardened containers (IronBank) and Policy as Code (PaC).
