This is an opportunity to shape the future of battlespace simulation through high-impact leadership, digital transformation, and advanced software systems design. Responsibilities may include but are not limited to: * Act as the principal technical liaison between engineering teams and government stakeholders, advising on software strategy, procurement (GOTS/COTS), and performance to align mission needs with technical deliverables
* Direct top-level software architectures for real-time simulation and complex behavior modeling, providing infrastructure recommendations to maximize scalability and reduce lifecycle costs
* Lead the transition from legacy frameworks to cloud-native, DevSecOps-enabled simulation platforms, ensuring alignment with contemporary digital engineering standards
* Oversee the integration of distributed simulation protocols (DIS, HLA, TENA) into the GRID-based Joint Simulation Environment (JSE) to facilitate seamless cross-domain interoperability
* Develop comprehensive simulation capabilities, including models, hardware interfaces, and user interfaces, utilizing C++ and modern development frameworks
* Mentor multi-disciplinary development teams while enforcing high standards for code quality, configuration management, and streamlined knowledge transfer through better documentation
* Define comprehensive test plan strategies and lead root-cause analysis for critical, system-level software issues to ensure robust performance and reliability Minimum Qualifications * Bachelor's degree in Computer Science, Computer Engineering, or related technical field
* 10+ years of progressively responsible experience in software engineering, including direct support to M&S initiatives
* Expertise with both on premise and cloud-based development environments (Azure and AWS)
* Expert-level proficiency in C++, with demonstrated experience designing and implementing high-performance simulation systems
* Hands-on experience using a wide variety of commercially available development tools such as the Atlassian Tool Suite (Jira, Confluence, Bitbucket), Git, and Microsoft Visual Studio
* Proven track record of leading digital transformation initiatives using Agile methodologies and CI/CD pipelines Preferred Qualifications * Experience with multi-level security environment development and deployment
* Experience utilizing cloud-based development environments and tools
* Direct experience supporting tactical aviation systems and distributed battlespace environments
* In-depth understanding of synthetic environment generation platforms such as NGTS, JSAF, or equivalent frameworks
* Strong communication skills with the ability to present complex engineering trade-offs to senior technical and non-technical audiences Clearance Requirements * Must possess an active Top Secret clearance with current SCI eligibility Physical Requirements * Must be able to remain in a stationary position approximately 50% of the time
* Occasionally required to move throughout office spaces to access equipment, files, or interact with co-workers
