Job description

Recommendation System Architecture Engineer‑ Soaring Star Talent Program

Responsibilities

Team Introduction: The ByteDance Recommendation Architecture Team is responsible for the design and development of the recommendation system architecture for ByteDance's related products. It ensures the stability and high availability of the system, optimizes the performance of online services and offline data streams, resolves system bottlenecks, and reduces cost overheads. The team also abstracts the common components and services of the system, builds the recommendation middle‑office and data middle‑office to support the rapid incubation of new products and enable ToB services.

Project Challenges

• Strategy Management and Optimization: Build an intelligent system to achieve standardized definition of recommendation strategies, long‑term and offline evaluation, automatic identification and retirement of ineffective strategies, and removal of related code configurations.
• Adaptive Tuning and Fault Diagnosis: Leverage large model capabilities to optimize parameters and configurations of systems and underlying components for diverse business loads in recommendation systems. Explore adaptive fault diagnosis solutions to provide global perspective for fault tracking, localization, and analysis.
• Cost‑Efficiency Balance: Address the high costs of model training and operation when applying generative technologies to recommendation systems, balancing costs and efficiency to achieve effective recommendation within limited resources.
• Cross‑Domain Data Processing: Handle massive heterogeneous data in horizontal cross‑domain scenarios (e.g., e‑commerce), improve and ensure data quality and accuracy, standardize data supply for cross‑domain recommendation models, and enable low‑cost cross‑terminal services. Meanwhile, ensure data privacy, security, and compliance.
• Data Storage and Quality Enhancement: Develop low‑cost, high‑performance storage engines, design flexible Schema Evolution mechanisms, achieve high‑concurrency real‑time data writing and training‑inference consistency. Deeply explore the quantitative relationship between data quality and model prediction performance, and build data‑model correlation analysis tools and automated training data processing pipelines based on the DCAI (Data‑Centric AI) concept.
• Multimodal Data and Heterogeneous Computing: Construct a multimodal data heterogeneous computing framework for recommendation systems to solve challenges in data reading, framework integration, and high‑performance operator orchestration, improving data processing and model training efficiency. Establish a developer ecosystem centered on Python.
• Large‑scale computing Model Efficiency Optimization for Recommendation: With continuous breakthroughs of large models in CV/NLP/multimodal fields and even towards AGI, large computing‑driven recommendation scenarios enable models to more comprehensively and profoundly understand user preferences, thereby better interpreting user needs, excavating latent interests, and delivering superior user experiences. Larger‑scale recommendation models demand greater computing. To balance computing overhead and effectiveness gains requires in‑depth Co‑Design by architecture and algorithm engineers.

Qualifications

• Got a doctor degree.
• Preferred fields: Artificial Intelligence, Computer Science, Mathematics, and related interdisciplinary majors.
• Academic achievements: Priority will be given to candidates with in‑depth research results and extensive practical experience in relevant fields, such as outstanding performance in natural language processing, computer vision, data modeling, or algorithm optimization.
• Coding skills: Excellent programming abilities with a strong command of data structures and fundamental algorithms. For traditional coding roles, proficiency in C/C++ is required; for intelligent coding roles, proficiency in Python is required. Candidates are required to use these languages to implement complex algorithms and build iterative models. Candidates should also have a strong engineering mindset with the ability to balance performance and cost.
• Machine learning skills: Strong foundation in machine learning, familiarity with commonly used models (e.g., decision trees, support vector machines), and the ability to build, train, and optimize machine learning models. Candidates should also be familiar with the latest AGI technologies, with the ability to quickly validate and explore their applications in e‑commerce generative recommendation.
• Communication and collaboration: Ability to effectively communicate and collaborate with team members, such as algorithm engineers, data analysts, and product managers, to explore new technologies and drive innovation in e‑commerce generative recommendation systems.
