Job Description Position Overview

At Takeda, we are building the next generation of intelligent R&D platforms by integrating Generative AI and agentic AI systems into drug discovery. We seek a Senior Scientist with deep expertise in AI model development to lead efforts in designing foundation models and autonomous agents that drive innovation across our therapeutic areas, including oncology, neuroscience, and inflammatory diseases.

This execution-focused role centers on the development and deployment of LLMs, generative protein models, and autonomous reasoning agents within an AI-first computational biology group. The ideal candidate will be a builder someone who can translate cutting-edge research in generative modeling into scalable, drug-discovery tools and autonomous pipelines.

Key Responsibilities

• Design and implement next-generation generative AI models for biologics discovery, including LLMs, protein language models, diffusion models, and multi-modal architectures.
• Build and refine agentic AI frameworks (e.g., tool-using agents, retrieval-augmented generation (RAG), memory-augmented LLMs) to autonomously plan and optimize designmaketestanalyze (DMTA) cycles.
• Collaborate with bioinformatics, automation, and wet-lab teams to build lab-in-the-loop systems , enabling AI agents to initiate hypotheses, request experiments, and iterate based on outcomes.
• Develop reusable AI pipelines that integrate multi-objective optimization (e.g., binding affinity, immunogenicity, developability, manufacturability) from in vitro and in silico data sources.
• Lead or contribute to the development of internal foundation models for biological design, including fine-tuning of LLMs on proprietary sequence, omics, and experimental datasets.
• Prototype and deploy agentic AI solutions using industry-standard frameworks such as LangChain, OpenAI API, Hugging Face Transformers, or similar.
• Stay current with advancements in transformer architectures, RLHF, memory systems, cognitive planning agents , and apply these innovations to real-world therapeutic discovery challenges.
• Clearly communicate ideas to cross-functional stakeholders and contribute to internal and external scientific knowledge-sharing.

Required Qualifications

• PhD degree in Computer Science, Computational Biology, Machine Learning, Bioinformatics, or related field (or equivalent) with 2+ years relevant experience, or MS with 8+ years relevant experience, or BS with 10+ years relevant experience Demonstrated expertise in developing large-scale deep learning models , including LLMs, generative models (e.g., diffusion, VAEs, autoregressive transformers), or multi-modal architectures.
• Proficiency in Python and modern ML frameworks (e.g., PyTorch, Hugging Face, JAX, LangChain); strong software engineering and reproducibility skills.
• Experience applying machine learning to biological sequences, experimental data, or computational biology pipelines (e.g., protein or antibody engineering, `omics analysis, etc.).
• Experience working with large datasets (NGS, high-throughput screens, bioassays) for supervised or unsupervised model training and evaluation.
• Deep familiarity with agentic AI design : planning agents, tool-using agents, memory-augmented LLMs, or lab automation interfaces (e.g., lab robots, simulation frameworks, or autonomous workflows).
• Proven ability to integrate AI models into production environments and iterative workflows, preferably within a pharmaceutical or biotech context.
• Excellent interpersonal and written communication skills; thrives in collaborative, interdisciplinary environments.

Preferred Qualifications

• Prior experience fine-tuning or training foundation models (e.g., ESM, ProGen, ProtGPT2, OpenFold, GPT-style LLMs) on biological or scientific data.
• Familiarity with retrieval-augmented generation (RAG) , tool-use planning, graph-enhanced reasoning, or long-context transformers for scientific applications.
• Knowledge of wet-lab feedback integration for DMTA cycles or closed-loop experimental platforms.
• Experience with cloud-based model deployment, distributed training, and model evaluation pipelines.
• Understanding of key drug-like properties (e.g., immunogenicity, aggregation risk, developability) and how to model them computationally.
• Demonstrated thought leadership (e.g., peer-reviewed publications, open-source contributions, patents) in GenAI or AI for biology.
