Channel3 is building a database of every product on the internet. Our API lets any AI app or agent add shopping capabilities and earn commission on sales.
Requirements
- Experience building AI systems from scratch
Responsibilities
- Write code to understand 100M products. Develop multimodal pipelines that extract structured attributes from PDPs, resolve canonical products across merchants, and link variants like size and color. We stitch together the latest language, embedding, image, and segmentation models to build a true understanding of each and every product.
- Build world-class search. Developers should be able to find “outdoor grills from Weber, less than $1000, with 4 burners,” “running sneakers under 300g, size 12,” or “this couch [image] but in green.”
- Engineer for reliability and cost. Create evals to measure drift, and guardrails to prevent regressions and hallucinations. Be clever and scrappy to reduce costs everywhere we can.
Other
- Students graduating in 2026/2027
- CS Majors with relevant extracurricular experience
- US citizen/visa only
- In-person in Manhattan, five days a week
- Ideally will convert to a full-time offer after graduation
