Job description

At VLGE, we are building the data infrastructure for physical AI, robotics, and spatial intelligence.

As AI expands beyond text and images into the physical world, the next generation of models requires something synthetic data can't replace: authentic human experience, judgment, and technique.

VLGE captures how people create, navigate, interact, and make decisions inside 3D and real-world environments, converting intuitive human expertise into rich, rights-cleared data for training AI systems.

Through our proprietary spatial and behavioral data layer, we turn human craft, motion, and interaction into structured intelligence,fueling world models, robotics, embodied AI, and digital twins across luxury, retail, entertainment, and enterprise environments.

VLGEAI is looking for a Senior Unity Developer to work closely with our AI engineers on developing the platform's core systems.

This role is highly hands-on and includes the most complex Unity and systems-level work currently built on VLGE. Over time, this role evolves into full technical ownership of the game engine features of the VLGE AI platform. The ideal candidate is comfortable architecting systems and writing scalable production Unity code aligned with the product roadmap.
