Software Engineer - Crowdsourcing Platform

About us:

Calder is solving the data bottleneck for embodied AI and world models. Today's AI models lack the real-world, 4D data needed to reason on spatial problems and operate in physical environments. We capture, process, and deliver high-fidelity human-generated spatial data at scale, providing the substrate that trains the next generation of generalizable models for manipulation, navigation, and interaction.

About the role:

The Task Platform connects people worldwide with opportunities to collect and contribute data for Physical AI. Demand across a wide range of customers and use-cases are mapped in real-time to a globally distributed supply leveraging heterogeneous sensor sets and collection modalities.

Physical AI is the largest economic opportunity since the industrial revolution and we aim to provide an economic opportunity for anyone, anywhere, while helping autonomous vehicles, manufacturing robots, and humanoids learn to operate in the real world.
