The role

You will build the AI that turns a sketch or a prompt into a 3D building. This is core to letting anyone construct on the digital Earth: the model, the safety layer and the pipeline that gets generated geometry into the world.

What you'll do

Build and fine-tune sketch-to-building and text-to-3D generation models.
Design prompt-safety and refusal behaviour so the generator stays on-rails.
Own the inference pipeline: latency, cost and quality at scale.
Collaborate with the 3D squad to make outputs game-engine ready.

What we're looking for

3+ years in applied ML, with generative models shipped to production.
Strong Python and PyTorch; comfortable with diffusion or transformer architectures.
Experience with 3D representations (meshes, voxels, point clouds, NeRF/Gaussian).
You ship pragmatic models that work, not just papers.
