ResponsibilitiesAbout the teamThe Seed LLM Code Generation Team is dedicated to comprehensively enhancing the model's coding capabilities and building a bridge for AI to interact with the digital world. Currently, the team focuses on key technologies such as large-scale automated synthesis of coding competitions/engineering problems, reinforcement learning for code agents, and construction of high-quality code pre-training datasets.We're building a Scientific Coding Agent—an LLM-driven system that plans, writes, debugs, and executes scientific code to accelerate physics/chemistry/Biology research. As a Research Intern, you'll help define how we evaluate scientific coding agents and explore agent evolution mechanisms that enable new scientific discoveries.PhD internships at ByteDance provide students with the opportunity to actively contribute to our products and research, and to the organization's future plans and emerging technologies. Our dynamic internship experience blends hands-on learning, enriching community-building and development events, and collaboration with industry experts.Applications will be reviewed on a rolling basis - we encourage you to apply early. Please state your availability clearly in your resume (Start date, End date).Responsibilities

• Benchmarking for scientific coding (core)
• Design a principled benchmark suite spanning tasks with literature-grounded coding and issues solving for existing codebase.
• Curate tasks/datasets and write robust unit tests with compliance of scientific knowledge.
• Implement evaluation metrics and build a clean, extensible evaluation pipeline with baselines.
• Language evolution for new scientific discovery (core)
• Prototype loops where agents propose/refine scientific language and tie these to executable code & simulations.
• Build workflows (multi-agents, planning, tool-use, self‑critique), integrate code execution sandboxes, retrieval, and experiment runners.
• Compare LLMs and inference strategies; run ablations and produce clean research artifacts (plots, tables, write-ups).

QualificationsMinimum Qualifications:

• Currently pursuing a PhD in Computer Science, Machine Learning, Programming Systems, Physics, Chemistry, Biology, Applied Math, or related field.
• Strong Python and software engineering: Git, testing (pytest), packaging, comfort with Linux/containers.
• Working knowledge of LLMs (prompting, fine‑tuning or adapters, evaluation) and at least one ML framework (eg. PyTorch).
• Solid foundations in physics and/or chemistry (e.g., classical/quantum/thermo/stat mech; physical chemistry, molecular modeling) and numerical methods (ODE/PDE, optimization, linear algebra).

Preferred Qualifications:

• Reinforcement Learning (PPO/DPO, reward modeling, curriculum learning).
