What you'll do

• Search algorithm design and optimization: Responsible for designing and developing efficient search algorithms suitable for the entire APP content, to meet users' precise search needs for various texts, images, videos, etc. Thoroughly analyze the characteristics of the APP's entire content and user search behaviors, optimize the search ranking algorithm, improve the relevance and accuracy of search results, and ensure that users can quickly obtain the required information.
• Recommendation algorithm design and optimization: Lead the research and development of content community recommendation algorithms, based on users' behavior data (browsing, liking, commenting, following, etc.), interest preferences, and content features, to build personalized recommendation models. Through optimizing the recommendation algorithm, increase the diversity, novelty, and user satisfaction of recommended content, increase user stay time and interaction frequency in the community, and have rich experience in recall-sorting full-chain modeling.
• Data processing and model training: Responsible for collecting, organizing, and analyzing the massive data of the APP's entire content, including user behavior data, currency information data, content metadata, etc. Through data mining technology, extract valuable features to provide high-quality data support for search and recommendation algorithms.
• Algorithm evaluation and effect improvement: Establish a scientific and reasonable algorithm evaluation system, use multiple indicators (such as accuracy, recall rate, click rate, conversion rate, etc.) to conduct regular evaluation and analysis of algorithm effects. Through A/B testing and other methods, compare the effects of different algorithm strategies, promptly identify problems and conduct targeted optimizations.
• Cross-departmental collaboration and business support: Work closely with product, operation, and development departments to deeply understand the business goals and user needs of APP search and content community. Integrate search and recommendation algorithms deeply with product functions to ensure that algorithms can effectively support business development, such as conducting precise recommendations in conjunction with operation activities to increase activity participation.

What you'll need

• Bachelor's degree or above, majoring in computer science, mathematics, statistics, artificial intelligence, etc.
• Have a solid theoretical foundation in machine learning and deep learning, familiar with common search algorithms (such as inverted index, BM25, etc.) and recommendation algorithms (such as collaborative filtering, content-based recommendation, deep learning recommendation models, etc.). Those who are familiar with natural language processing and computer vision basics are preferred, as it will help better handle multi-dimensional data in large-scale search.
• Have more than 3 years of experience in search or recommendation algorithm-related work, and have project experience in fields such as cryptocurrency APP search recommendation, content communities, social media or information platforms, etc.
• Proficient in Python programming, proficient in at least one deep learning framework (such as PyTorch, TensorFlow) or machine learning library (such as Scikit-learn), and able to independently complete the development, training and optimization of algorithm models.
• Familiar with data processing and analysis tools, such as SQL, Pandas, etc., and have the ability to handle large-scale data sets. Those who are proficient in big data processing frameworks such as Hadoop and Spark are preferred, to cope with the challenges of massive data from large search data sources.
• Have good algorithm implementation and code optimization skills, able to write efficient and maintainable code. Familiar with common development tools and version control systems, such as Git.
• Have strong research capabilities and innovative consciousness. Those who have published papers on search, recommendation or related fields in well-known academic conferences or journals are preferred, or those who have achieved excellent results in related competitions are preferred.
• Have a good team spirit and communication skills, able to effectively collaborate with personnel from different professional backgrounds to achieve project goals. Be able to quickly understand business requirements and convert them into feasible technical solutions, have good problem-solving abilities and the ability to analyze complex problems.
