Principal Software Engineer - Simulation & Digital Twin Architect

Job Description At General Motors, our product teams are redefining mobility. Through a human-centered design process, we create vehicles and experiences that are designed not just to be seen, but to be felt. We're turning today's impossible into tomorrow's standard -from breakthrough hardware and battery systems to intuitive design, intelligent software, and next-generation safety and entertainment features. Every day, our products move millions of people as we aim to make driving safer, smarter, and more connected, shaping the future of transportation on a global scale. The Role We're hiring a Principal Simulation & Digital Twin Architect to lead the software architecture for GM's manufacturing Digital Twin & Simulation Platform. You'll set the technical vision, connect best-in-class simulation engines and plant systems, and drive a multi-year roadmap that shapes how GM designs, validates, and runs our factories. What you'll do Own the end-to-end architecture for GM's manufacturing Digital Twin & Simulation stack (plant models, AMR/cobot and equipment simulation, material flow, and integrations with PLM, CAD, MES, and data platforms). Define and maintain enterprise reference architectures, APIs, and data contracts used across plants and business units. Architect scalable data schemas and pipelines for ingesting and managing plant and floor data for both simulation and operational twins. Design modular, distributed simulation architectures that balance fidelity and cost across cloud and on-prem environments (e.g., Kubernetes, GPU clusters, data lakes). Lead cross-functional, multi-team initiatives; align teams and vendors to shared architectures and standards. Act as a principal technical voice for Digital Twin & Simulation, mentoring senior/staff/principal engineers and influencing technical direction across GM. What you bring Master's or PhD in Computer Science, Software Engineering, Robotics, Electrical/Computer Engineering, or related field. 10+ years of software engineering experience, including principal-level architecture or technical leadership for large-scale, multi-team platforms or systems. Deep experience with at least one major 3D or manufacturing simulation environment (e.g., Unity, Unreal, NVIDIA Isaac/Omniverse). Proven track record integrating systems across PLM/CAD, MES/production, PLC/controls, and data/analytics platforms. Strong programming skills in C++, C#, Python, or similar, with experience designing APIs, services, and data models. Experience with cloud and on-prem environments (e.g., Kubernetes, GPU clusters, data lakes) for high-scale simulation and Digital Twin workloads. Nice to have Experience with manufacturing and industrial automation: material-handling systems, AMRs, cobots, virtual commissioning, or PLC/HMI-driven digital twins. Familiarity with Teamcenter, Siemens Technomatix Process Simulate, or similar manufacturing engineering tools. Experience with SiL/HiL setups, scenario-based testing, and CI/CD-integrated simulation workflows. Understanding of cybersecurity and data governance for connected factory systems. This role is categorized as remote. This means the selected candidate may be based anywhere in the country of work and is not expected to report to a GM worksite unless directed by their manager. The selected candidate will be required to travel
