G2 Ops supports mission-critical defense and technology initiatives by solving complex operational and engineering challenges. We are seeking a motivated, collaborative Software Engineer / MBSE Plug-in Development, Mid to support Java-based modeling tool capabilities, SysML model generation, and AI-assisted engineering workflows.

In this role, you’ll contribute to software engineering, model-based systems engineering, and digital engineering capabilities while working alongside a team that values innovation, technical excellence, and continuous growth.

• Develop and maintain JAVA-based software components and software application extensions
• Implement software capabilities for automated data processing, visualization, and workflow generation including, but not limited to: system architecture, component relationships, and process workflows
• Build and maintain parsers and data models for structured JSON inputs that drive model generation
• Use and extend internal utility libraries wrapping modeling APIs for semantic and presentation element creation
• Collaborate with AI engineering teams to align plugin behavior with LLM output expectations and improve robustness of AI-assisted generation workflows

• Diagnose and resolve issues across UI, parsing, API integration, and backend generation logic
• Contribute to code quality improvements, validation logic, and testing strategy across multi-repository codebase
• Support iterative feature delivery and coordinate with cross-functional teams to ensure plugin capabilities align with modeling workflows

• Bachelor's degree in Computer Science, Software Engineering, or related technical field
• 3+ years of professional Java development experience
• Experience designing and maintaining object-oriented systems in production codebases
• Strong proficiency with JSON parsing/serialization and schema-driven data models
• Ability to debug complex workflows across UI, parsing, API integration, and backend logic
• Experience integrating software with REST or HTTP-based APIs
• Strong communication skills and ability to collaborate across technical teams
• Ability to obtain and maintain required security clearance

• Experience building plugins for Cameo Systems Modeler, Magic Draw, or similar modeling tools
• Familiarity with SysML, MBSE, and model-based engineering concepts
• Experience with modeling tool APIs, sessions/transactions, and diagram automation
• Experience with Eclipse-based plugin environments or JavaFX/Swing UI development
• Experience integrating AI/LLM capabilities into engineering workflows
• Familiarity with prompt/schema design for structured LLM output

Your code will directly enable systems engineers to rapidly develop high-quality models for defense systems that protect national security. You'll work on technically challenging problems at the intersection of software engineering, AI integration, and model-based systems engineering.

A pragmatic Java engineer comfortable working in a specialized engineering domain who understands how structured data maps into model elements and diagrams, can debug issues across repository boundaries, and delivers features iteratively while maintaining technical rigor.
