Responsibilities
Team Introduction
The mission of our AML team is to push next-generation machine learning algorithms and platforms for the recommendation system, ads ranking and search ranking in our company. We also drive substantial impact on core businesses of the company.
Responsibilities:
1. Resource Efficiency Optimization in Distributed Orchestration and Scheduling：
- Develop and extend distributed orchestration frameworks within the Kubernetes/Godel ecosystem. Select appropriate frameworks based on different business scenarios, and optimize cluster utilization and load balancing strategies according to the specific characteristics of each scenario;
- Integrate and expand AutoScaling and automatic parallelization capabilities for various models and tasks. Employ load modeling and analytic methods for different models to automatically optimize resource requests, achieving large-scale improvements in resource usage efficiency and global optimality;
- Responsible for preemption and re-scheduling mechanisms for services with different prioritties, and manage automatic resource multiplexing across different clusters and resource types; handle scheduling and load adaptation across multi-datacenter, multi-region, and multi-cloud environments.
2. Building Training System Architecture for Next-Generation Ultra-Large and Ultra-Deep Recommendation Models:
- Develop a flexible, elastic and robust distributed training runtime focused on hyper-scaled embeddings and large-scale GPU training;
- Design and optimize distributed computing APIs and runtimes geared towards future recommendation and ads model paradigms (e.g., reinforcement learning, fine-tuning and/or distillation);
- Collaborate with platform teams to enhance the diagnosability and usability of distributed training systems.
3. Constructing Online Orchestration Architecture for Next-Generation Recommendation Systems:
- Build a robust distributed model inference architecture for online learning scenarios involving hyper-scaled embeddings;
- Optimize the usability of online recommendation and ads model architectures and MLops workflows.
