任职资格

1、数学、统计、计算机等相关专业硕士及以上学历；

2、熟练使用至少一种主流机器学习框架（如Tensorflow,Pytorch,Scikit-learn)，精通Python编程语言;熟练掌握SQL;

3、熟悉业界常用的机器学习算法、推荐排序算法和技术。熟悉黑盒模型的可解释性方法;

4、良好的逻辑思维能力，对数据敏感，能够发现关键数据、抓住核心问题，学习能力强，有强烈的责任心，良好的沟通协调能力；

5、具备强烈的业务意识和数据驱动思维，能独立完成从业务理解到模型上线的完整闭环。

Job Description

You will be more than just an engineer building models — you'll need to deeply understand users and products, translate business problems into algorithmic challenges, and leverage advanced machine learning techniques to drive business metric improvements.

Key Responsibilities:

Business Insight & Problem Definition: Develop a deep understanding of business scenarios and work closely with product, operations, and other teams to identify core pain points and opportunities in recommendation, ranking, preference prediction, and related areas. Translate ambiguous business requirements into clear, quantifiable, and solvable algorithmic problems.

Algorithm & Model Development and Optimization: Design, implement, and optimize model algorithms and strategies, including but not limited to classical machine learning models, embeddings, sequence models, deep learning models, and multi-objective modeling.

System Deployment & Performance Evaluation: Drive the deployment of algorithmic models in production systems, A/B testing, and performance monitoring; design and analyze A/B experiments to scientifically evaluate the impact of algorithm iterations on business metrics, and clearly communicate data-driven insights to non-technical teams; continuously monitor online model performance, rapidly diagnose and resolve model anomalies.

Qualifications:

Master's degree or above in Mathematics, Statistics, Computer Science, or a related field.

Proficient in at least one mainstream machine learning framework (e.g., TensorFlow, PyTorch, Scikit-learn); expert-level Python programming skills; strong proficiency in SQL.

Familiar with industry-standard machine learning algorithms, recommendation and ranking algorithms, and related technologies. Familiar with interpretability methods for black-box models.

Strong logical thinking skills and data sensitivity — able to identify key data signals and pinpoint core problems. Fast learner with a strong sense of ownership and excellent communication and collaboration skills.

Strong business acumen and data-driven mindset; capable of independently driving the full lifecycle from business understanding to model deployment in production.
