Job description

Why Sabel Systems

Sabel Systems designs and delivers digital engineering ecosystems for DoD programs, enabling teams to connect data, systems, and personnel within secure, scalable environments. Our solutions empower programs to make faster decisions, close sustainment gaps, and meet the digital acquisition requirements.

Sabel Systems designs and delivers digital engineering ecosystems for DoD programs, enabling teams to connect data, systems, and personnel within secure, scalable environments. Our solutions empower programs to make faster decisions, close sustainment gaps, and meet the digital acquisition requirements.

Rather than simply proposing transformation, we implement and operate it at scale. Our method is clear: we orchestrate existing tools into a governing system of record, ensuring government ownership of infrastructure and traceable decisions. There's no vendor lock, no proprietary baselines, and no need for ATO rebuilds during transitions.

Sabel Systems is redefining modern defense acquisition. If you seek to solve complex challenges at scale and want your work to directly accelerate military capability while reshaping the DoD's approach to digital engineering, this is the place for you.

Complexity Simplified. Mission Amplified.

What You'll Do

• Assess existing customer data models and architectures, determining necessary modifications for implementing compliant SysML and/or UAF models in accordance with industry standards, DoD directives, and MBSE Style Guides
• Develop and maintain prototype software pipelines and data transformation workflows that support automated SysML and/or UAF model generation and validation
• Utilize Cameo to propose, develop, and iterate on behavioral and structural diagrams supporting Business Process Model Notation (BPMN) workflows, mission threads, operational scenarios, and program data in accordance with SysML and UAF standards
• Lead quality assurance, validation, and refinement of SysML and UAF outputs to ensure models are fit for purpose, technically accurate, compliant with applicable style guides, and support customer decision-making
• Collaborate directly with internal teammates, sister organizations, and customers via MS Teams, video conferences, and email to understand modeling requirements, validate assumptions, and provide technical guidance
• Participate in requirements elicitation sessions, design reviews, and trade studies with systems engineers, program managers, and domain experts to ensure models capture operational intent and stakeholder needs
• Provide remote and in-person product demonstrations and training to customers, presenting model outputs and recommending improvements in clear, accessible language
• Attend daily stand-ups, sprint planning sessions, sprint reviews, retrospectives, and other team meetings on time; actively contribute to continuous process improvement
• Manage individual work tasks and deliverables within project management systems (Jira); provide accurate status updates and elevate risks and issues proactively
• Operate in compliance with DoD security requirements, handling classified and controlled unclassified information (CUI) appropriately
