LLM Algorithm Engineer

Manus is a general-purpose AI agent that bridges mind and action, handling complex tasks from start to finish. It enables people to delegate entire workflows across deep research, data analysis, and software development, turning advanced AI into reliable, practical results.

About the Role

Improve LLM and agent capabilities through post-training research and experimentation. Work across data strategies, training methods and evaluation to diagnose task performance issues and bring research improvements into products.

Responsibilities

Research and refine LLM post-training methods and training recipes, designing experiments around target tasks to improve performance and generalization. Build and iterate on training data, adjusting quality, distribution and usage strategies in response to capability goals and experimental results. Design benchmarks and evaluations that cover target capabilities and practical use cases, providing a consistent basis for comparing training approaches.

Analyze model behavior and recurring failures, formulate improvement hypotheses, and test them through training experiments while documenting results and their conditions. Work with product, engineering and model partner teams to incorporate application feedback into data, training and evaluation, and assess results on real tasks.

Requirements

Solid foundations in machine learning and LLMs, with research or practical experience in large-scale foundation model training or post-training and familiarity with SFT, reinforcement learning or preference optimization. Proficiency in mainstream deep learning frameworks, with the ability to set up experiments independently, analyze training results and diagnose problems.

Understanding of how data and training methods affect model performance, with the ability to plan improvements based on evaluations and practical use cases. Active engagement with relevant research and independent research judgment, with the ability to formulate testable hypotheses from open-ended problems and evaluate them rigorously.

Manus excels at various tasks in work and life, getting everything done while you rest at Manus AI.
