About the team
Our team works on large-scale recommendation systems for various offerings under TikTok and its affiliates, focusing on developing recommendation algorithms/models/strategies.
Responsibilities
- Work on recommendation systems, involving contents of various forms ranging from products, short videos to live streams, with each unified recommendation model fulfilling heterogeneous Ecommerce scenarios/goals across multiple countries.
- Optimize ecommerce recommendation models at massive scales, using deep learning/transfer learning/multitask learning techniques.
- Data mining and analysis to improve the quality of recommended contents.
- Conduct research on various topics, which aim to optimize content recommendation circulation, ranging from ensuring diversity and new discovery in recommendation contents, to coldstart problem for new users/items and discovery of highquality products/live streamers.
- Develop innovative and stateoftheart ecommerce models and algorithms
- Support the production of scalable and optimised AI/machine learning (ML) models
- Focus on building algorithms for the extraction, transformation and loading of large volumes of realtime, unstructured data to deploy AI/ML solutions from theoretical data science models
- Run experiments to test the performance of deployed models, and identifies and resolves bugs that arise in the process
- Work with the relevant software platforms in which the models are deployed
Qualifications
- Strong in data structures and algorithms, with excellent problemsolving ability and programming skills
- Experience in applied machine learning, familiar with one or more of the algorithms such as Collaborative Filtering, Matrix Factorization, Factorization Machines, Word2vec, Logistic Regression, Gradient Boosting Trees, Deep Neural Networks etc.
- Experience in working with main components of recommendation systems(recall, sort, reranking, coldstart problem), with good understanding of mainstream recommendation models used in the industry
- Experience in C++ and Python; at least one of the Big Data tools (For eg. Hive sql/Spark/Mapreduce; at least one of the Deep Learning tools(For eg. Tensorflow/Pytorch)
- Possess strong communication skills, positive mindset, good teamwork skills, and eagerness to learn/implement new technology and experiment
Preferred Qualifications
- Experience in personalized recommendation, online advertising, information retrieval or related fields.
- Publications at KDD、NeurIPS、WWW、SIGIR、WSDM、CIKM、ICLR、ICML、IJCAI、AAAI、RecSys and related conferences
- Excellent performance in data mining, machine learning, or ACM-ICPC/NOI/IOI competitions
- Developed widelyrecognized machine learning project(s) on github or personal webpage
To achieve that goal, we are committed to celebrating our diverse voices and to creating an environment that reflects the many communities we reach.
We are passionate about this and hope you are too.More jobs from NodeFlair
