Senior Digital Twin Engineer — Vehicle Modelling & AI

Rivian and Volkswagen Group Technologies; Irvine (CA); On-site; USD 150,000 - 190,000; Full time

Job summary

Rivian and Volkswagen Group Technologies in Irvine, CA, seeks a Systems Design Reliability Engineer to advance AI‑assisted, model‑driven systems for vehicle subsystems. You will build and operate Digital Twin infrastructure, create co‑simulation environments, and own end‑to‑end features from plant models to test pipelines.

The role combines hands‑on systems engineering with AI tooling, requiring Python expertise, experience with OpenModelica/Simulink, and a practical mindset for rapid

Qualifications

• BS/MS in Electrical, Computer, Mechanical, or Systems Engineering, or related field — or equivalent demonstrated experience through projects.
• Strong Python skills — data processing, prototyping AI workflows, automation scripts, or microservices.
• Practical experience building LLM applications: RAG pipelines, semantic search, structured reasoning, or agent frameworks.
• Systems-minded: able to decompose a physical product into subsystems, behaviors and interfaces — and reason about how they interact.
• Comfort iterating quickly from prototype, to production, using modelling in a fast‑paced engineering environment.

Responsibilities

• Digital Twin development & operation for multi‑fidelity plant models (FMU), vehicle subsystems.
• Develop and run co-simulation environments to pair vECUs with plant models.
• Model-to-code simulation to validate control requirements before production code.
• SIL regression tests with nightly CI to catch regressions and broaden coverage.
• Field issue replay to verify fixes virtually before shipping.
• Correlate models with real vehicle and fleet data.
• Build LLM pipelines for requirement drafting, test scripts, and coverage analysis.
• Deploy semantic search and RAG over SE artifacts; integrate AI into GitLab & CI/CD.
• Author requirements and test cases; participate in architecture and safety reviews.
