Principal Software Engineer - Simulation & Digital Twin Architect

Role Description

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.

Qualifications

• 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.

Requirements

• 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.

Benefits

• This role is categorized as remote. 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 <25% for this role.
• This job may be eligible for relocation benefits.
