Video already accounts for ~80% of internet traffic and has become the dominant medium for creativity, communication, gaming, AR/VR, and robotics — and truly modeling it depends on high-quality training data, which is what Sieve builds. They combine exabyte-scale video infrastructure, novel video-understanding techniques, and dozens of diverse data sources to produce datasets that push the frontier of video modeling, earning the trust of frontier AI labs, Fortune 100s, and fast-growing generative‑AI startups. They did multiple millions in revenue last quarter alone with a team of ~15. Founded: 2022 | Team size: ~15 | Stage: Series A (Matrix Partners, Swift Ventures, Y Combinator, AI Grant) | Total funding: Not disclosedIndustry: AI Tools / Video DataWebsite: sievedata.comOffice: San Francisco, CA Why Candidates Should Join Frontier customer base: Work directly with the most technically demanding organizations in the world — frontier AI labs and Fortune 100s. Genuine generalist scope: A role that spans product, applied research, customer engagement, and operations — high leverage, real company-level exposure. Early and proven: ~15-person team already doing multiple millions in quarterly revenue, scaling fast. The Role Sieve is hiring a Research & Product Lead to be a high-leverage generalist operator across the company — combining deep technical fluency with strong relationship skills to manage Sieve's most important customer accounts, drive cross-functional execution, and contribute wherever the company needs leverage. It sits at the intersection of product, applied research, customer engagement, and operations. The role exists because Sieve's customers are the most technically demanding organizations in the world and the team is scaling fast; managing those relationships and the operations behind them requires someone who can operate as a peer with the engineers and researchers they work with while building the systems that let the company scale. The team is open to two profiles: Senior track: experienced operators with existing AI-lab relationships or a background at a human-data company (Scale, Surge, Sapien, Mercor, Invisible, Toloka, Snorkel, Defined.ai, or similar). Generalist track: 1–2 years out of consulting (MBB or top tier), banking, or as an APM at an AI company, paired with an engineering degree and demonstrable technical curiosity. Across both tracks, the universal filter is high curiosity and high EQ.

Background at a human data company (Scale, Surge, Sapien, Mercor, Invisible, Toloka, Snorkel, Defined.ai). Direct adjacency to Sieve’s market and customer base. For the junior track: 1-2 years out of consulting (MBB or top tier), banking, or as an APM at an AI company, paired with an engineering degree. Scrappy, high curiosity, high EQ. Comfortable debugging a data pipeline question and navigating a commercial expansion conversation in the same hour. Treats relationship management as a craft. Prior early-stage startup experience, especially as an early hire who saw a customer-facing function get built from zero.
