Role Descriptions & Responsibilities

As a MBSE Java Developer, you will play a key role in shaping the future of Model-Based Systems Engineering (MBSE) by contributing to MagicDraw, one of the most advanced modeling platforms in the world, part of the Dassault Systèmes CATIA ecosystem. You will operate at the intersection of language design, complex system modeling, and high-performance engineering tools. Your work will directly impact how leading organizations such as NASA, Boeing, Airbus, BMW, and Renault design and validate complex systems. You will be expected to own problems end-to-end, influence technical direction, and contribute to the evolution of the SysML v2 standard implementation. Some more of your responsibilities will include the following:

• Drive the design and implementation of core SysML v2 modeling capabilities

• Take ownership of complex, ambiguous problems and deliver robust, scalable solutions

• Contribute to technical architecture decisions and long-term product direction

• Deeply understand and help shape the implementation of the SysML v2 standard

• Improve system performance, memory usage, and model scalability for large-scale engineering models

• Analyze product metrics and real-world usage to guide engineering improvements

• Collaborate across teams (R&D, QA, Customer Success) to resolve complex technical challenges

• Advocate for and implement engineering best practices (clean code, TDD, code reviews, CI/CD)

• Build and maintain automated testing strategies for complex modeling scenarios

Qualifications

• Master’s degree in Computer Science, Engineering, or related field

• This position will require you to be onsite at our Plano office.

• 4+ years of experience in Java and complex software systems

• Strong expertise in Core Java and system-level design

• Strong experience with Git and collaborative development workflows

• Experience with CI/CD pipelines (Jenkins, TeamCity, etc.)

• Proven ability to design and debug large, complex, object-oriented systems

• Experience with performance optimization, memory management, and scalability

• Solid understanding of TDD, JUnit, and testing strategies for non-trivial systems

• Comfortable working in Agile environments, but able to operate independently

• Familiarity with modeling languages (SysML/UML) or domain-specific languages is a strong plus

• Excellent communication skills, able to explain complex ideas clearly

• High ownership mindset, you take responsibility for outcomes, not just tasks

• What Success Looks Like:

• Work on deeply technical, intellectually challenging problems (not CRUD apps)

• Influence the evolution of next-generation engineering standards (SysML v2)

• Build software used to design real-world complex systems — aircraft, vehicles, space systems

• High level of autonomy and technical ownership

• Collaborate with top-tier engineers and domain experts globally

• Continuous growth through complex challenges, architecture work, and peer learning

• Be part of a stable, innovation-driven company with a long-term vision #LI-HYBRID Shape your career with3DS! #WeAre3DS
