High-quality video, audio, image, and interaction data for frontier AI. Backed by Y Combinator and AI Grant.
About the role
As part of our Business Operations team , you'll work directly with our executive team to translate strategic priorities into operational reality. This isn't a scheduling or note-taking role, you'll own ambiguous, cross-functional problems end-to-end, stand up new functions from scratch, and bring rigor to how the company operates as it scales. Work directly with leadership team to identify, prioritize, and drive the company's strategic initiatives
What they're looking for
- 2-5 years of experience in a high-ownership, cross-functional role, chief of staff, business operations, strategy & operations, management consulting, or founding a company
- Experience at a hyper-growth startup, ideally one that scaled quickly and required building new functions and processes from scratch
- Some technical fluency — comfortable having technical conversation, especially in the multi-modal data space, understanding basic infrastructure or model training concepts, or working directly with engineers, even if you're not an engineer yourself
- Strong business operational instincts: comfort with financial models, dashboards, and translating ambiguous goals into concrete plans
- High agency and a bias toward action. You should be comfortable picking up unfamiliar problems and driving them to resolution without much guidance
- Strong organizational skills and the ability to manage multiple concurrent work-streams without dropping details
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.
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. We're growing fast, and the systems, processes, and functions that got us here won't be the ones that get us to the next stage. You'll join at the point where you can have outsized leverage: close enough to leadership to shape decisions, hands-on enough to build the functions that don't exist yet.
