Technical Recruitment Sourcer

About Us 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 also raised our Series A from Tier 1 firms such as Matrix Partners , Swift Ventures , Y Combinator , and AI Grant .

Sieve is one of the most capital-efficient teams in AI - roughly 30 people serving the world's leading AI labs across every major data modality. You'll join early, own problems end-to-end, and the hires you make will help define the future of multimodal models.

As a Full-Cycle Technical Recruiter, you'll own recruiting for engineering and product roles across Sieve. You'll source technical candidates via LinkedIn and web-based sourcing, run screening calls, manage our Ashby pipeline, coordinate interviews, and close offers. This isn't a back-office role - you'll work directly with hiring managers to understand what we need, own the candidate experience end-to-end, and build the processes and templates that make recruiting scalable as we grow.
