[Remote] Student Researcher [Seed LLM - Code Generation] – 2026 Start (PhD)

Note: The job is a remote job and is open to candidates in USA. ByteDance is a pioneering company dedicated to advanced AI foundation models. The Seed LLM Code Generation Team is looking for a PhD intern to enhance coding capabilities through research and development in AI, focusing on code generation and reinforcement learning.

Responsibilities

• Develop methods for code generation and editing using large language models, including improving performance on tasks such as synthesis, repair, documentation, and test generation
• Conduct research on self-evolving agents that can learn to write, edit, and optimize code over time with minimal supervision
• Explore multi-agent reinforcement learning settings where agents collaborate, compete, or communicate to solve complex programming tasks
• Investigate instruction tuning, multi-turn prompting, retrieval-augmented generation, and RL for program synthesis
• Build benchmarks and tools for evaluating model performance in code understanding, collaborative reasoning, and long-horizon programming scenarios

Skills

• Currently pursuing a PhD in Computer Science, Machine Learning, Programming Systems, or a related field
• Research experience in code generation, program synthesis, or LLMs for software engineering
• First-author publications in top venues such as NeurIPS, ICLR, ICML, PLDI, or OOPSLA
• Familiarity with LLM toolchains (e.g., HuggingFace, PyTorch) and structured code/data handling
• Experience with reinforcement learning or agent-based learning in structured environments
• Background in multi-agent coordination, curriculum learning, or self-improving systems
• Understanding of software reasoning tasks such as static analysis, refactoring, or automated debugging
• Familiarity with open code benchmarks (e.g., HumanEval, MBPP, CodeContests, SWE-bench)

Benefits

• Interns have day one access to health insurance
• Life insurance
• Wellbeing benefits and more
• Interns also receive 10 paid holidays per year
• Paid sick time (56 hours if hired in first half of year, 40 if hired in second half of year)
