Think of it as talking to a stylist who truly gets you. We’re a small, fast-growing, VC-backed startup reshaping how people discover fashion online. Our founding team includes two former DoorDash and Airbnb product leaders, data scientists and engineers, who are also fashion influencers and photographers. Plush launched in 2024 and has already gained meaningful traction, with tens of thousands of high-intent users and strong early revenue traction.

Exploring social discovery features: Power community-driven recommendations and enhance product discovery (e.g., “people with similar taste loved this” or “you and your friend share a love for minimalist tailoring”). Establishing evaluation pipelines: Measure and improve search and LLM performance—tracking relevance, coverage, latency, and output quality. You Might Be a Great Fit If 3+ years of experience working on machine learning, search, and recommendation systems. Comfortable designing both quick prototypes and scalable infrastructure. Strong product intuition and care about what users experience. High ownership, clear communication, and thrive in fast-moving environments.
