This role offers a unique opportunity to build foundational models trained on vast clinical data and drive innovation in a highly meaningful domain.

Job Responsibility:

  • Lead the development, training, and deployment of large language and multimodal foundation models tailored to clinical and biomedical domains
  • apply and refine state-of-the-art techniques such as supervised fine-tuning (SFT), reinforcement learning-based methods (e.g., RLHF, RLVR), parameter-efficient fine-tuning (PEFT), prompt tuning, and retrieval-augmented generation (RAG)
  • Collaborate cross-functionally with researchers, clinicians, and engineers to design ML-driven solutions that improve healthcare delivery and outcomes
  • Build scalable infrastructure for distributed training of large models (TPU/GPU clusters, multi-node orchestration)
  • Design and evaluate models for robustness, bias mitigation, factual consistency, and explainability in healthcare contexts
  • Stay current with the latest research in generative AI and contribute back to the community through publications and open-source initiatives

Requirements:

  • 6+ years of experience in software engineering or machine learning (3+ years with a PhD)
  • Experience designing and training LLMs or large-scale generative models (e.g., GPT, PaLM, LLaMA, Claude, Gemma)
  • Deep expertise in NLP, sequence modeling, and transformer architectures
  • Proficient in Python and ML libraries such as PyTorch or TensorFlow
  • strong engineering skills in building scalable ML pipelines
  • Experience with RL-based fine-tuning (e.g., Reinforcement Learning from Human Feedback) and evaluation of generative systems
  • Proven ability to lead technical projects and collaborate across teams
  • Bachelor's degree in Computer Science, Engineering, or a related technical field

Nice to have:

  • PhD or equivalent experience in Machine Learning, NLP, AI, or a related field
  • Experience in healthcare, biomedical informatics, or clinical data modeling
  • Familiarity with multi-modal foundation models (e.g., text-image, text-structured data) and cross-modal alignment techniques
  • Hands-on experience with vector databases, semantic search, and retrieval-based generation
  • Publications in top-tier ML conferences (NeurIPS, ICML, ACL, EMNLP, ICLR, etc.)
  • Experience building trustworthy AI systems and applying model interpretability, fairness, and safety frameworks
What we offer:
  • Interesting and meaningful work for every career stage
  • Great benefits package
  • Comprehensive benefits with strong medical, dental and vision insurance plans
  • 401K plan
  • Professional development & training opportunities for continuous learning
  • Work/life autonomy via flexible work hours and flexible paid time off
