About the role

As Sieve's first roboticist, you'll own the physical side of our physical AI data: the robots, capture rigs, and teleoperation stations that generate the datasets we deliver to frontier labs. You'll take each system from parts on a table to a setup that records clean, synchronized data at a partner site, and you'll handle both the hardware and the software along the way. Found on 1752vc Careers, the job board for startup and VC roles.

More about this role

Sieve is a multi-modal lab curating the world's highest-quality training datasets — spanning video, audio, images, text, and 3D. We combine exabyte-scale data infrastructure and novel multimodal understanding techniques that push the frontier of foundation models. Video alone makes up 80% of internet traffic, and across modalities, data has become the enabling medium powering creativity, communication, gaming, AR/VR, and robotics. Sieve exists to solve the biggest bottleneck in the growth of these applications: high-quality training data.

We partner with top AI labs and did $XXM last quarter alone, as a team of ~30 people. We also raised our Series A from Tier 1 firms such as Matrix Partners , Swift Ventures , Y Combinator , and AI Grant .
