About The Position

We are seeking a Senior Simulation Software Engineer for the Digital Twin team with deep expertise in at least one major simulation environment (Unity, Unreal Engine, or NVIDIA Isaac Sim) and a willingness to learn others. In this role, you will design, build, and scale core software services and high‑performance 3D simulation environments, program NPC behaviors, and support automation workflows for autonomous robotics development. You will combine 3D programming with strong platform engineering to deliver reliable, low-latency simulations at enterprise scale.

Requirements

• Bachelor’s or Master’s degree in Computer Science, Game Development, Robotics, or a related field
• 5+ years of software engineering experience, including 3D simulation development or game engine programming
• Expertise in at least one of: Unity3D, Unreal Engine, or NVIDIA Isaac Sim, with a willingness to learn others
• Proven experience productizing 3D software systems (e.g., rendering pipelines, physics, simulations, or digital twins)
• Strong skills in NPC programming and behavior scripting
• Proficiency in C#, C++, or Python, with strong foundations in computer graphics and linear algebra
• Solid CI/CD, version control (Git), and agile development practices

Nice To Haves

• Experience with robotics simulation and autonomous systems
• Knowledge of physics-based simulation and AI-driven behaviors
• GPU/compute expertise (HLSL/GLSL/Compute Shaders), materials/shaders, and graphics debugging tools (e.g., RenderDoc, PIX, Nsight)
• Experience in manufacturing, automotive, or industrial domains
• Knowledge of cybersecurity best practices for connected systems

Responsibilities

• Develop and maintain simulation environments using Unity, Unreal Engine, or NVIDIA Isaac Sim
• Implement NPC programming and behavior logic to enable realistic interactions
• Own end-to-end features: requirements, architecture, implementation, testing, deployment, and observability
• Build high-performance 3D simulation modules (rendering, physics, spatial indexing) for scalable, real-time execution and integrate them with platform services
• Develop asset pipelines and tooling for ingesting, transforming, and optimizing complex 3D assets (e.g., USD, glTF) and scene graphs for real-time use
• Collaborate with robotics engineers and software developers to integrate simulation with automation pipelines
• Contribute hands-on to coding and code reviews, promoting clean code practices and secure development standards
• Troubleshoot and resolve technical issues in simulation frameworks
• Document workflows, tools, and best practices to enable cross-team adoption
