About the Role. 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., * 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, MagicDraw, 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

Why This Role Matters

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.

Ideal Candidate: 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.

## Description

* Develop and maintain Java-based plugin functionality for Cameo Systems Modeler / MagicDraw
 * Implement SysML model generation capabilities including Block Definition Diagrams, Internal Block Diagrams, and Activity Diagrams
 * 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

Collaboration & Quality (30%)

 * 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
