Role Overview

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. We're based in NYC, backed by Matrix, Ludlow, and Y Combinator.

Responsibilities

  1. Write code to understand 100M products.
  2. Develop multimodal pipelines that extract structured attributes from PDPs, resolve canonical products across retailers, and link variants like size and color.
  3. 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."
  4. Engineer for reliability and cost. Create evals to measure drift, and guardrails to prevent regressions and hallucinations.
  5. Be clever and scrappy to reduce costs everywhere we can.

Requirements

We're moving fast: We're up and running, with 500+ developers building on our API, customers eagerly awaiting features, enterprises inbounding, and millions of products processed every day. You'll have direct ownership of technical and infrastructure decisions, roadmap, and prioritization. You'll help us grow the team and build our culture from the ground up. We're backed by the best: We just closed a $6M seed round led by Matrix (Apple, FedEx, Afterpay) with participation from Ludlow (Honey, StockX), Y Combinator, and Paul Graham.

Setup and Perks

In-person in Manhattan, five days a week. Company laptop. Health insurance. Dinner provided in the office Monday-Thursday.
