High Speed Systems Engineer

Leidos • Huntsville, AL

5d • Onsite

About The Position

Leidos Defense Systems is seeking a highly motivated Systems Engineer to drive Value Driven Design and advanced Model-Based Systems Engineering (MBSE) workflows across complex, high-priority Department of Defense portfolios. The role bridges systems architecture, parametric lifecycle modeling, and cross-functional engineering execution, supporting critical national security hardware and software environments. The engineer will lead requirements and architecture working groups, develop automated tool integrations using Cameo Systems Modeler, and oversee the verification lifecycle. The position requires full-time onsite work in a controlled area (SCIF environment) and travel of 10–20% to customer and partner organizations. U.S. citizenship and an active TS clearance are mandatory.

Requirements

• Bachelor’s degree in Aerospace Engineering, Systems Engineering, Mechanical Engineering, Electrical Engineering, Industrial Engineering, Computer Engineering, Physics, or a related STEM discipline, with 4+ years of experience.
• Proficiency with MBSE methodologies and direct architecture capture using SysML-compliant tools, specifically Cameo Systems Modeler or MagicDraw.
• Hands-on experience developing or managing complex structural allocations, such as Block Definition and Internal Block Diagrams from L0 through subsystem levels, and generating automated documents or reports using VTL, Python, or MATLAB.
• Experience drafting, analyzing, and decomposing technical requirements, preferably using EARS or automated requirements-management tracking databases such as DOORS.
• Strong communication skills and proven ability to lead small technical teams, align multidisciplinary engineering divisions, and present effectively internally and externally.
• Ability to work full-time onsite in a controlled area (SCIF environment) and willingness to travel 10–20% to customer and partner organizations.
• U.S. citizenship.
• Active TS clearance.

Nice To Haves

• Master’s degree in Aerospace Engineering, Systems Engineering, Mechanical Engineering, Electrical Engineering, Industrial Engineering, Computer Engineering, Physics, or a related STEM discipline, with 4+ years of experience.
• Industry experience in high-speed dynamics, aerothermodynamics, hypersonics, or advanced propulsion.
• Advanced, administrative, or power-user experience with Cameo Systems Modeler / MagicDraw, IBM DOORS, SIMIO, or equivalent enterprise MBSE and requirements databases.
• Familiarity with DoD acquisition lifecycle and program processes.
• Experience applying parametric cost modeling, Monte Carlo techniques, or advanced mathematical trade studies to defense hardware acquisition programs.
• ASEP/CSEP (INCOSE) or OMG Certified Systems Modeling Professional (OCSMP) credentials.
• Active Top-Secret security clearance with SCI eligibility.

Responsibilities

• Lead structural and behavioral capture of high-speed system architectures in Cameo Systems Modeler / MagicDraw, maintaining unified SysML Logical, Physical, and Allocative views.
• Oversee creation, maturation, and tracking of constrained-syntax requirements using EARS-aligned paradigms, ensuring requirement-to-verification traceability and test artifact mapping.
• Develop, expand, and maintain parametric manufacturing and Operations and Support (O&S) lifecycle models using Excel, Python, and MATLAB to assess design alternatives and conduct sensitivity analysis.
• Formulate, manage, and facilitate multidisciplinary requirements and architecture working groups to define cross-functional engineering interfaces and open-architecture configuration management.
• Direct trade studies, technical decision briefs, and executive white papers evaluating warfighter utility, manufacturing readiness, and lifecycle cost/benefit tradeoffs.
• Build custom Velocity Template Language (VTL) scripts in Cameo to automate contract deliverables, Interface Control Documents (ICDs), and program milestone design reviews.
• Provide technical leadership within a matrixed team environment.
