Parallel Domain builds the platform that validates the next generation of autonomous systems in high-fidelity virtual environments. Our content and rendering pipeline is how that platform earns its credibility with customers. The virtual environments we build have to hold up under physical, geometric, and sensor-level scrutiny—they are the testbeds against which our customers' autonomous systems are validated. Building environments at that level of fidelity and scale demands techniques that go beyond a typical AAA game pipeline. Gaussian splat scene reconstruction, neural rendering, AI-assisted content workflows, and modern procedural systems are reshaping what a tech artist's day looks like. We're hiring a Principal Technical Artist to bring the next generation of these workflows into production at Parallel Domain. This is a senior individual contributor role: you'll work alongside our rendering, simulation, and content engineers on open-ended content and pipeline problems. You'll move fluently between Unreal Engine, Houdini, Python, shader code, and modern AI tooling, and your judgment will shape how our team builds the environments that train and validate autonomous systems.
