Our goal is to integrate generative models with evaluation/simulation/experimental data to form an iterative, deliverable R&D workflow. You will develop key modules across the stack—from data to models to decision-making layers—and work closely with domain experts to turn scientific constraints into computable optimization objectives. Responsibilities： You will work end-to-end along the core loop: Data → Generation → Evaluation → Iteration: Data & Representations：Integrate public datasets and internal data sources (experiments, computations, literature). Perform cleaning, standardization, deduplication, and data quality assessment. Build high-quality datasets for training and benchmarking. Generative Model Development：Design, train, and optimize generative model (e.g., Transformers/GPT, Diffusion, Flow Matching). Support structure generation and optimization for chemistry/materials objects. Multi-objective & Constrained Generation：Translate multiple property targets and physical/chemical constraints into computable conditions. Enable controllable generation and trade-off optimization across multiple metrics. Evaluation & Decision Layer：Build reliable evaluation and decision modules (scoring, filtering, re-ranking, uncertainty estimation). Improve validity, robustness, and reproducibility of generated results. Engineering & Cross-functional Delivery：Collaborate with domain experts and experimental/simulation teams. Build reproducible pipelines (training/inference/evaluation/monitoring). Deliver actionable candidates and milestone reports to support closed-loop iteration. Requirements： M.S. degree or above (Ph.D. preferred) in CS/ML/computational chemistry/materials science or related fields. Strong deep learning fundamentals; proficiency with PyTorch/TensorFlow; ability to write clean, modular, maintainable research/production code. Hands-on experience with at least one class of generative models: Transformer/GPT, Diffusion, or Flow Matching (training, tuning, inference, evaluation). Strong data/system skills: able to independently build data pipelines, manage experiments, design metrics, and perform error analysis. Strong cross-disciplinary collaboration skills: able to abstract domain constraints into algorithmic problems and drive implementation. Preferred Qualifications： · Applied experience in AI for Science (chemistry/materials/biology/physics). Familiarity with RDKit, molecular/materials structure toolchains, GNNs, and/or reinforcement learning. Experience with distributed training, inference acceleration, and industrial-grade tuning/experiment tracking (e.g., Weights & Biases, MLflow, Optuna). Experience integrating models into real R&D workflows (service deployment, reliability, monitoring, regression testing).
