About the role

Redwire is seeking a Systems Engineer to contribute to concept of operations development, mission solution design, and strategic analysis for spacecraft programs supporting National Security Space. This role spans space domain awareness, space resiliency, mission autonomy, structures, sensors, and next-generation space systems. You will develop, integrate, and govern modeling, simulation, and digital engineering frameworks that support mission system and space system architectures, blending physics-based modeling, MBSE discipline, and multi-domain simulation expertise.

Responsibilities

• Develop and enhance modeling & simulation capabilities including physics-based and AI-augmented models.
• Apply and promote MBSE practices across the full system lifecycle.
• Build simulation and analysis models supporting concept development, demonstrations, proposals, and system-level evaluations.
• Create and maintain digital twins & digital threads for space systems and mission architectures.
• Design and simulate system interfaces across multi-domain engineering environments.
• Perform virtual integration and V&V for simulation components and end-to-end system behavior.
• Assess system performance using technical performance measures and simulation-based criteria.
• Contribute to concept development through modeling, documentation, and architectural analysis.
• Communicate technical results via reviews, proposals, and stakeholder briefings.
• Collaborate across engineering and business teams to support program execution and business capture.

Requirements

• STEM education — B.S. in Aerospace, Systems, Mechanical, Industrial Engineering, or related field.
• Systems Engineering Experience — 1–5 years in system development, I&T, MBSE, or operations or related STEM job.
• Modeling & simulation development — Experience developing new or enhanced modeling and simulation capabilities.
• Digital engineering & MBSE — Ability to apply MBSE, SysML, and digital engineering tools across the lifecycle.
• Simulation & analysis modeling — Experience building models for concept development, demonstrations, and system-level evaluation.
• Digital twins & digital threads — Ability to create and evolve digital twins for mission and space systems.
• Cross-disciplinary collaboration — Work with subsystem engineers to develop detailed designs and analyses.
• Interface design & simulation — Ability to model and simulate system and subsystem interfaces.
• Virtual integration & V&V — Experience validating simulation components and integrated system behavior.
• Performance assessment — Ability to evaluate system performance using defined metrics.
• Concept development — Experience contributing to conceptual system design and documentation.
• Technical communication — Ability to present simulation results and design artifacts.
• Cross-functional teamwork — Ability to collaborate with engineering, IT, management, and business development.
• U.S. Citizenship with ability to obtain DoD clearance.
• Ability to travel 10–15%.

Skills

• MBSE & SysML proficiency — Hands-on experience with MBSE and SysML.
• MBSE tooling — Cameo Systems Modeler, Teamwork Cloud, or similar tools.
• Physics-based modeling — MATLAB/Simulink or Python scientific libraries.
• Systems engineering depth — Understanding of space vehicle design, architecture, and mission development.
• Communication & detail orientation — Strong written and verbal communication skills.
• Independent engineering execution — Ability to independently apply systems engineering principles.
