Our work spans key areas including community recommendation, search, AI-powered search, translation, and multilingual foundation models. In early 2025, our LLM-powered translation technology gained widespread attention, showcasing the team's technical capabilities and impact. Global expansion calls for a fundamental rethinking of how we build products. Unlike mature businesses focused on continuous optimization, rednote offers us a genuine 0-to-1 opportunity: fewer legacy constraints, greater potential for innovation, and the chance to reshape search and recommendation algorithms through an AI-native approach. Here, you'll tackle some of the most challenging algorithmic problems in real-world global business scenarios, including multilingual understanding, cross-cultural relevance, cold-start challenges, and cross-domain understanding. If you're eager to explore uncharted territory and solve complex technical challenges, join us in building the next generation of community products for users around the world. 【Job Responsibilities】 1. Recommendation Algorithms Drive the implementation and development of recommendation technologies at rednote. Deliver technical breakthroughs in personalized recommendations, content distribution strategies, user understanding, and content understanding. 2. Search Algorithms Drive the implementation and development of search technologies at rednote.
