This position provides research, and supports the development of UAF/DODAF views tailored to the systems engineering and integration (SE&I) efforts for the future development of capabilities for the MDO environment needed for the operational testing of Future Vertical Lift, Maneuver (XM30 and Robotic Combat Vehicle), Intelligence Electromagnetic Warfare & Cyber (TITAN/TLS), and Next Generation Command and Control (NGC2) Systems Under Test (SUT). The selected candidate will work at our office in Killeen, TX, four days a week, with one day of remote work per week. This role is responsible for developing viewpoints (Operational, Service, etc.) and model-based systems engineering (MBSE) models that demonstrate what additional capabilities are needed for the MDO environment that supports the operational testing of future vertical lift, XM-30/RCV, & TITAN/TLS systems under test. Additionally, outputs from the SE&I effort support the development of test functions and objectives as part of future course of action development that will be submitted to the government. This position will report to the Innovation Cell Manager. This is an exciting opportunity to pioneer the product development of the MDO Environment and associated Data planning, preparation, monitoring, and assessment tools for Operational Test environments. This role will require creativity and innovation to combine the discipline of Systems Engineering with larger program and corporate objectives., * Conduct trade studies to include cost-benefit analyses to develop cost-efficient systems for specific projects. * Identify stakeholder, customer, and user needs and assess the root cause of the needs. Based on that information, design UAF/DODAF views for a new system or improve existing systems to enhance their functionality and efficiency. * Derive and manage requirements that guide the development of courses of action for the government to make decisions on solutions that close gaps in the Multi-Domain Operations environment needed for Operational Testing. * Perform Systems Engineering activities such as requirements development and traceability, system model development, design documentation, and verification and validation analysis over the lifecycle of the MDO environment gap closure development effort. * Support the Model-Based Systems Engineering (MBSE) processes within standard toolsets in a manner that enables efficient and effective response to changing mission needs and rapidly evolving system requirements to model operational testing processes for test and evaluation with the AOTI Systems Engineering team. * Coordinate with program management personnel to prioritize programmatic and technical objectives. * Maintain requirements baseline within MBSE tools to ensure consistency across all areas of engineering concern (e.g., mission and user requirements, system functions and attributes, and architectural and design components). * Assist in managing software interface requirements and definitions. * Less than 25% travel may be required. ## Related Videos - [Security Pitfalls for Software Engineers](https://www.wearedevelopers.com/videos/726-security-pitfalls-for-software-engineers) - [Model Based Systems Engineering in an Agile Product Development Process](https://www.wearedevelopers.com/videos/68-model-based-systems-engineering-in-an-agile-product-development-process) - [ShapeShift: Reinventing Agile for a B2B SaaS Scale-Up](https://www.wearedevelopers.com/videos/1655-shapeshift-reinventing-agile-for-a-b2b-saas-scale-up) - [Automated Driving - Why is it so hard to introduce](https://www.wearedevelopers.com/videos/628-automated-driving-why-is-it-so-hard-to-introduce) - [From Punch Cards to AI-assisted Development](https://www.wearedevelopers.com/videos/611-from-punch-cards-to-ai-assisted-development) - [The ABC of DX](https://www.wearedevelopers.com/videos/727-the-abc-of-dx) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering)
