Senior M&S Systems Developer; SME

Overview

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 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 from strategic planning to tactical execution, enabling NATO forces to conduct complex multi-domain operations analysis and training.

You will be the technical POC who translates operational requirements into scalable, interoperable systems using distributed computing technologies and industry-standard protocols like DIS and HLA.

This position requires a unique blend of technical leadership and domain expertise. You will 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.
