Senior Simulation Software Engineer

Job Description

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.

What You'll Do (Key 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

Your Skills & Abilities (Required Qualifications)

• 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

What Can Give You a Competitive Edge (Preferred Qualifications)

• 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

This role is categorized as hybrid. This means the selected candidate is expected to report to a specific location at least 3 times a week {or other frequency dictated by their manager}.

The selected candidate will be required to travel <25% for this role.
