Job Description:
SimIS, Inc. is seeking a Senior Software Architect - Modeling & Simulation SME to lead the technical design and development of NATO's Next Generation M&S capability. This critical role combines advanced software architecture expertise with deep knowledge of military simulation systems to create the future of NATO's warfare simulation infrastructure.

The successful candidate will architect distributed simulation environments that operate seamlessly from strategic planning down to tactical execution, enabling NATO forces to conduct complex multi-domain operations analysis and training. You will be the technical POC who helps transforms operational requirements into scalable, interoperable systems using cutting-edge distributed computing technologies and industry-standard protocols like DIS and HLA.
This position requires a unique blend of technical leadership and domain expertise. You'll design high-level architectures that integrate legacy systems while building next-generation capabilities, ensuring real-time data exchange across global NATO commands. Your work will directly impact NATO's ability to plan, execute, and analyze military operations through advanced simulation technologies.

The candidate performs the following specific assignments:Design and implement high-level architecture for NATO's next-generation M&S systemsLead DIS protocol implementation and ensure compliance with IEEE standardsArchitect distributed simulation environments supporting multi-location exercisesDevelop software components for real-time simulation interaction and data exchangeCreate technical specifications for system interfaces and integration pointsDesign scalable architectures supporting political-to-tactical level simulationsImplement middleware solutions for simulation interoperabilityLead technical reviews of architecture designs and code implementationsDevelop APIs for connecting legacy systems (JCTS, JTLS) to new architectureOptimize network performance for distributed simulation environmentsDesign data synchronization mechanisms for distributed databasesCreate architectural patterns for turn-based and real-time simulation modesTechnical Architecture Focus:Define enterprise-level M&S architecture standardsImplement publish-subscribe patterns for distributed event handlingDesign fault-tolerant systems for mission-critical simulationsDevelop microservices architecture for modular simulation componentsCreate containerized deployment strategies for cloud and on-premise environmentsMinimum Experience Requirements within the last 5-10 years:At least 5 years developing distributed simulation systems using DIS/HLA protocolsAt least 3 years designing high-level system architectures for military simulation environmentsProven experience architecting systems that support real-time interaction between multiple simulation nodesExperience developing APIs and interfaces for simulation interoperabilityStrong background in performance optimization for large-scale distributed systemsExperience with both mission-level and campaign-level simulation developmentBS in Computer Science, Software Engineering, Computer Engineering, or related discipline.Experience Desired:Experience with NATO STANAG standards for simulationKnowledge of military C4ISR systems integrationFamiliarity with game engines adapted for military simulationCloud architecture experience (AWS, Azure)DevOps and CI/CD pipeline experiencePMP or technical architecture certifications
