Join our Digital Technology team and play a key role in driving digital transformation across our global Supply Chain organization while collaborating with talented professionals around the world.

We are looking for a Senior Principal Engineer to lead and mature our Model-Based Systems Engineering (MBSE) capability. The role owns the end-to-end system model, from requirements through architecture to simulation-based verification, using Cameo Systems Modeler and SysML.

You will define modeling methodology, guide project teams, and connect the system model with multi-domain simulation (MATLAB/Simulink) and the wider digital thread, enabling traceable, reusable and product-line-ready engineering.

• →Lead requirements modeling and architecture modeling (structure, behavior, interfaces, allocation) for complex multi-domain systems in Cameo and SysML.
• →Define and govern MBSE methodology, modeling standards, profiles, patterns and reusable libraries across programs.
• →Develop and maintain the full set of SysML views in Cameo: Requirement, Block Definition, Internal Block, Parametric, Package, Activity, Sequence, State Machine and Use Case diagrams.
• →Integrate and co-simulate Cameo models with MATLAB/Simulink to validate requirements and establish bidirectional requirements traceability and linkage between system models and simulation models.
• →Establish and drive product line engineering practices: variability modeling, feature models, configuration of product variants and reuse of model assets.
• →Contribute to the digital thread by linking MBSE artifacts with PLM, ALM, simulation and test data so that traceability is maintained across the lifecycle.
• →Perform trade studies, impact analysis, verification and validation planning, and design reviews using the system model as the single source of truth.
• →Mentor and coach engineers, run MBSE training and workshops, and act as technical authority in reviews with internal and external stakeholders.
• →Evaluate emerging standards and tools (including SysML v2 and its API) and recommend adoption of roadmaps.
• →Define guidelines for the safe, governed use of AI/GenAI in MBSE (requirements quality checks, model generation and review, traceability, model debugging), with human validation of every AI output.
• →Technology proposal preparation and funding opportunity exploration, leading efforts in innovation, filling invention disclosure, external paper publication, productivity savings through automation, models.

• →Aerospace architecture requirements: You will gain depth in the emerging system architecture needs of aerospace systems and learn how to capture and model them in a way that is traceable, verifiable and reusable across programs. You will develop the methods that can be easily adaptable in other business unit and mature the same before handing it over the business unit.
• →Innovation beyond project delivery: Alongside your regular project execution, you will get exposure to proposal development, business development opportunities and invention disclosures, learning how to turn technical ideas into funded work and protectable intellectual property.
• →Mentoring and coaching: You will learn to coach, train and guide young engineers in MBSE methods and tools, building the skills to grow technical talent, run workshops and set modeling standards for a team.
• →Technical leadership: You will learn to act as a technical authority, influencing design decisions and stakeholders across disciplines and programs.

• B.E./B.Tech in Mechanical, Electrical, Electronics, Aerospace, Automotive, Mechatronics, Instrumentation/Controls or Computer Science.
• M.E./M.Tech/MS in Systems Engineering, Systems and Control, Mechatronics, Aerospace/Automotive Engineering, or a related discipline. A PhD in a relevant area is an advantage.

• 13–15 years of experience in systems engineering, with a substantial portion in hands-on MBSE & PLE.
• Expert-level proficiency in Cameo Systems Modeler (MagicDraw) and SysML v1.x, with working knowledge of all diagram types.
• Strong experience in requirements engineering and requirements modeling, including derivation, decomposition, allocation and verification traceability.
• Proven experience in architecture modeling: functional, logical and physical architectures, interface definition and behavior modeling.
• Hands-on experience integrating or co-simulating Cameo with MATLAB/Simulink (for example via Simulation Toolkit, FMI/FMU or Simulink integration) for requirements validation and traceability.
• Experience in product line engineering: variability management, feature modeling, and tools or methods such as 150% models, Pure::variants or equivalent.
• Basic understanding of the digital thread concept and of integration with PLM/ALM tools (for example Teamcenter, Windchill, DOORS, Jama, Codebeamer).
• Solid grounding in systems engineering lifecycle processes (ISO/IEC/IEEE 15288, INCOSE SE Handbook) and in V&V practices.
• Excellent communication, stakeholder management and technical leadership skills.
• AI/LLM, Agentic workflows, RAG models for requirements checking, debugging and verifying AI outputs.
• Knowledge of SysML v2 (textual and graphical notation, KerML, standard API).
• Experience with Cameo add-ons such as Cameo Simulation Toolkit, Cameo Collaborator, Teamwork Cloud, and OpenAPI/Open MBEE integrations.
• Scripting or automation for modeling (Java, Python, Groovy, Cameo OpenAPI, SysML v2 API).
• Domain experience in automotive, aerospace, defense, industrial or energy systems.
• Familiarity with safety and reliability analysis in the model (FMEA, FTA, hazard analysis) and standards such as ISO 26262 or ARP4754A.
• Exposure to digital twin and model-based testing.
• Working knowledge of AI/GenAI-assisted MBSE (requirements analysis, model generation and review, traceability, and model debugging).
• INCOSE ASEP / CSEP / ESEP (Associate, Certified or Expert Systems Engineering Professional)
• OMG Certified Systems Modeling Professional (OCSMP), Model Builder level, preferably Intermediate or Advanced
• Other recognized systems engineering credentials, such as Dassault/No Magic Cameo certifications or equivalent
• MATLAB/Simulink certifications (for example MathWorks Certified Associate/Professional)
• Product line engineering certification (for example Pure::variants or BigLever training)
• SAFe, PMP or similar, for leading cross-functional programs
• Systems thinking and the ability to simplify complexity into clear models
• Technical leadership and influence without direct authority
• Strong ownership, curiosity and a mindset of continuous improvement
• Collaboration across mechanical, electrical, software, controls and test teams, mentoring and training young engineers.

We at ART develop technologies which are needed for the business unit to adapt to the product line, we are the central organization supporting all other business units for developing technology and methodologies. We own the technology in early research or TRL’s and mature the proof of concept and hand it over to the engineering process excellence team which can be adoptable into the BU product line or process. We work with global ART stakeholders and BU stakeholders in developing the technology and understanding the requirements, we align with collings key technology strategies and BU technology roadmaps.
