Position Description

ENSCO Inc. is a diverse engineering and technology company that provides engineering, science, and advanced technology solutions supporting mission success, safety, and security for government and commercial customers worldwide.

We are seeking a Lead System Architect to work directly with Government mission leaders and independently governed program teams delivering elements of a critical space mission capability. Each participating organization may hold a different architecture vision, acquisition path, technical baseline, funding profile, and delivery schedule. This role creates trusted relationships and shared technical evidence needed to bring those efforts together.

The MILSATCOM Systems Engineering, Integration, and Test (MSEIT) effort provides leading edge Systems Engineering & Integration (SE&I) for the Space Force’s Space System Command. We support the Space Force’s acquisition of state of the art Military Satellite Communications systems, providing global secure, survivable, and protected communications for our nation’s warfighters. We seek technical individuals who will thrive in a highly collaborative work environment of small teams, using the most modern tools and methodologies to tackle the challenges of integrating complex space and ground communications systems.

Primary Responsibilities:

• Serve as the Lead System Architect for MBSE, providing technical leadership, direction, and oversight for system modeling activities across the program

• Develop and maintain the program's MBSE strategy, modeling approach, architecture, governance, and roadmap in alignment with program systems engineering objectives and Digital Engineering initiatives

• Define and maintain the overall model architecture, including model organization, decomposition, viewpoints, relationships, naming conventions, modeling standards, and modeling patterns

• Lead development and maintenance of integrated system models representing system architecture, requirements, behaviors, functions, interfaces, verification relationships, and other elements of the technical baseline

• Establish and maintain traceability between mission needs, operational capabilities, system architecture, requirements, interfaces, verification activities, and supporting engineering artifacts

• Define the approach for integrating and, where appropriate, federating models and engineering data produced by government organizations, development contractors, support contractors, and other stakeholders

• Evaluate contractor-developed models and modeling approaches for consistency with program architecture, requirements, technical baseline objectives, and established modeling standards

• Manage the configuration of a Teamwork Cloud database employing multiple Project Usages

• Manage the data connectivity between Cameo System Modeler and IBM Rational DOORS

• Work closely with requirements engineers to establish and maintain relationships and traceability between modeled architecture and authoritative system requirements

• Work with interface engineering teams to ensure system interfaces, logical and physical connections, exchanges, and dependencies are consistently represented within the model

• Work with verification and test organizations to incorporate verification methods, relationships, evidence, and system behavior into the modeling environment as appropriate

Qualifications Required

• Bachelor’s degree in engineering, computer science, or related technical field

• At least 5 years of experience in satellite systems, spacecraft development, or aerospace engineering, including at least 4 years of hands-on experience with Cameo Systems Modeler/MagicDraw or comparable enterprise MBSE environments.

• Demonstrated experience leading MBSE efforts for complex systems

• Strong working knowledge of systems engineering principles across architecture, requirements, interfaces, verification, validation, and configuration management

• Demonstrated experience developing and managing complex system models using SysML

• Experience developing model structures, modeling conventions, viewpoints, relationships, and reusable modeling patterns

• Experience establishing traceability among system architecture, requirements, interfaces, behaviors, and verification information

• Experience with model configuration management, baselining, version control, and model governance

• Ability to assess complex system models
