Job Description

Be part of a fast-paced, high energy, team supporting the Resilient Missile Warning/Missile Tracking (Resilient MWT) Medium Earth Orbit (MEO) and Ground Management and Integration (GMI) program to engineer increasingly complex systems and capabilities. The government is transforming its systems engineering methods and processes. Central to the transformation is the use of Model Based Systems Engineering (MBSE) as the means to manage complexity, increase engineering quality, and ultimately drive cost and schedule efficiencies into the acquisition process. As an industry leader in systems engineering, Arcfield is actively hiring Model Based Systems Engineering MBSE Modelers and subject matter experts to drive this transformation across the government.

For this position, the selected candidate is responsible for participating in the adoption of MBSE in both customer and company domains. The candidate should have experience modeling systems in SysML, UAF or UML languages. They should also have demonstrated experience with how system requirements, design, analysis, verification and validation activities are enabled by MBSE across the digital thread (the engineering lifecycle). Foundational to MBSE are tools, technologies, and methodologies that can collectively be called digital engineering. The selected candidate should demonstrate experience with industry MBSE tools and modeling methodologies to successfully produce systems engineering models.
