Responsibilities

This positon is for Strategic Technology Consulting (STC), an Arcfield company Strategic Technology Consulting (STC), an Arcfield Company, is seeking an experienced Model-Based Systems Engineer (MBSE) to support complex national security and space systems engineering initiatives. This role requires applying advanced digital engineering tools, MBSE methodologies, and systems engineering practices to support transformative space-based sensing systems. The selected candidate will work closely with government leadership, acquisition stakeholders, mission engineers, systems engineers, and cross-functional technical teams to develop digital models, system architectures, trade-space analyses, technical documentation, and acquisition-focused engineering products that support portfolio-level decision making. This is a unique opportunity to contribute to mission-critical space-based sensing, targeting, and collection architectures using modern digital engineering approaches.

• Model-Based Systems Engineering: Apply MBSE methodologies across the lifecycle of complex space systems, including concept development, integration, verification, validation, transition, and technical maturation.
• Digital Model Development: Create digital models that support acquisition lifecycle activities, including concept definition, pre-acquisition planning, technology maturation, trade-space analysis, and technical decision support.
• Space Systems Engineering: Support the design and evaluation of resilient system-of-systems architectures across space, ground, communications, and multi-domain mission segments.
• Trade Studies and Analysis: Conduct feasibility studies, technical gap analyses, trade-off analyses, Analysis of Alternatives, and predictive simulations to evaluate collection architectures, mission performance, technical risk, and capability alignment.
• Engineering and Acquisition Support: Translate high-level operational needs and mission requirements into technical acquisition strategies, design-level solutions, technical performance metrics, and portfolio-level engineering recommendations.
• Collaboration and Stakeholder Engagement: Interface with government leadership, acquisition teams, mission partners, and cross-functional stakeholders to ensure engineering products align with acquisition, operational, and technical objectives.

Qualifications

• BS 8-10, MS 6-8, PhD 3-5 in Systems Engineering, Aerospace Engineering, Electrical Engineering, Computer Science, or a related technical discipline.
