Systems Engineer (MBSE Integrator)

The n Logic team is seeking a Senior Systems Engineer to join our team in the Huntsville, AL area.

The Senior Systems Engineer will lead efforts to integrate Model-Based Systems Engineering (MBSE) tools and practices across program and customer teams, including administration and development of the program model and metamodel in Cameo.

This role includes coordinating with customer modeling teams, enhancing and maintaining functional and architectural models, and integrating additional capabilities such as Reliability/Availability/Maintainability (RAM) analysis and parametric data profiles. The candidate will support functional and behavioral analysis in the context of defeating ballistic, aero‑maneuvering, hypersonic, hyper‑glide, and complex threats across Missile Defense Agency (MDA) mission areas.

The Senior Systems Engineer will lead requirements development, system-of-systems analysis, and Change Notice (CN) updates to MDA system specifications. This position requires significant collaboration across engineering teams and direct engagement with customer stakeholders.

Responsibilities

Lead integration and implementation of MBSE capabilities and tools.

Serve as an administrative owner for the program’s Cameo model and metamodel, including updates, maintenance, and configuration oversight.

Coordinate program-level model integration with customer models at multiple levels.

Enhance the functional architecture model with additional capabilities, such as RAM analyses and parametric integration of numerical profiles.

Conduct functional and behavioral analysis to support defeat concepts for advanced threat systems.

Support development of system-of-systems requirements through trade studies, analysis, and collaborative modeling.

Lead the development of Change Notices (CNs) to MDA’s system specification, including updates to:

functional requirements

interface definitions

performance requirements

architectural models

Maintain and evolve architecture models, metamodels, and interface definitions.

Perform traceability and verification from system-level to element-level requirements.

Develop and deliver technical products, such as briefings, design review artifacts, and stakeholder documentation.

Collaborate directly with customer teams and support Digital Design Reviews using model-based artifacts

Required Qualifications

Active Secret Clearance

Bachelor’s, Master’s, or PhD in Engineering, Mathematics, Physics, or related technical field.

Demonstrated systems engineering experience with large, complex systems.

Strong background in architecture development, functional decomposition, and allocation of performance, functional, and interface requirements.

Hands-on experience with MBSE tools, specifically Cameo/MSOSA and DOORS.

Experience maintaining architecture models and metamodels.

Demonstrated ability to lead and brief model-based design reviews (e.g., Digital Design Review).

Strong analytical skills and the ability to capture concepts in papers, briefings, and technical discussions.

Effective communication and presentation skills; ability to work both independently and within a small team environment.

Experience coordinating directly with customer stakeholders.

Preferred Qualifications

Experience modeling, analyzing, or simulating missile defense or related domains, such as:

Aegis Weapon System

Ground-based Midcourse Defense (GMD)

Glide Phase Intercept (GPI)

Hypersonic and Ballistic Tracking Space Sensor (HBTSS)

Fire Control and C2BMC

EO/IR/RF sensor systems

Kill vehicles and interceptors

Ballistic and non-ballistic target engagements

Space vehicles or sub‑orbital mechanics

Knowledge of advanced threat systems

Experience serving as an architecture model administrator.

Knowledge of integrating AI/automation techniques within MBSE to improve productivity and model quality

Candidate must be a U.S. Citizen. This is a full-time, on-site position located in Huntsville, AL. Current SECRET clearance is required for consideration.
