Senior Applied Scientist, Generative AI (GenAI)

We are seeking a Senior Applied Scientist, Generative AI (GenAI) to lead the development and deployment of advanced AI models that power critical clinical applications. This role will balance hands-on model development with close collaboration with engineering teams to ensure seamless integration and optimization of AI models in production environments. You'll play a pivotal role in driving innovation across multiple AI initiatives, from clinical report generation to agentic workflows that utilize natural language commands. 

Ideally, this person would be able to work out of our San Francisco office but remote from the United States also works. If remote, we'd like this individual to be able to fly into the San Francisco office as needed to collaborate with other scientists, engineers and executives during key strategic planning sessions.  This would likely be 3-4 days in total over the course of a quarter. The first week of employment would include onsite onboarding in our San Francisco office.

Key Responsibilities:

• Design, develop, and fine-tune generative AI models for clinical applications, including semi-automated medical report generation, patient data summarization, and clinical decision support.
• Implement robust evaluation pipelines to benchmark model performance, detect drift, and ensure continuous improvement.
• Prototype and integrate AI models into real-world healthcare applications, collaborating with product and engineering teams to push models into production.
• Conduct research and experimentation to optimize LLMs, NLP models, and multimodal approaches for healthcare tasks.
• Explore and prototype agentic workflows that leverage natural language voice commands to enhance clinical workflows.
• Evaluate and integrate third-party algorithms and AI models, leveraging LLMs to improve functionality and system performance.
• Stay on top of emerging trends and advancements in AI, with a focus on identifying opportunities for innovation in clinical applications.
  

• PhD in Data Science, Computer Science, Machine Learning, Computational Linguistics, or related fields; or Master's degree combined with equivalent relevant industry experience.
• Strong expertise in traditional machine learning techniques (supervised/unsupervised), statistics, and hypothesis testing.
• 8+ years of experience applying machine learning and AI to real-world problems, with a focus on NLP and LLMs.
• Proficiency with Python, SQL, and popular data science libraries such as pandas, NumPy, scikit-learn, and PyTorch.
• Proven experience with generative AI and NLP methods, including prompt engineering, embeddings/vector databases, retrieval-augmented generation (RAG), LLM evaluation, and fine-tuning techniques.
• Strong track record in deploying AI models to production and conducting rigorous model performance evaluations. Hands-on experience fine-tuning closed and open-source models and integrating them into production systems.
• Strong understanding of model deployment pipelines and experience maintaining AI models in a production environment.
• Ability to communicate effectively with both technical and clinical teams, translating complex AI concepts into actionable insights and performant models.

• Healthcare domain experience, especially in clinical workflows and regulated environments.
• Computer vision experience or experience developing multimodal models that combine text, imaging, and structured clinical data.
• Experience building or fine-tuning LLMs from scratch, with a focus on healthcare data.
• Strong engineering background with the ability to set up, maintain, and optimize AI infrastructure (open and closed source).
• Contributions to open-source AI frameworks or libraries.

• Make a Real Impact: Your work will directly affect patient outcomes and improve clinical workflows for healthcare providers.
• Work with Cutting-Edge AI: You'll be at the forefront of applying AI innovations in a high-stakes domain.
• Collaborate with Top Talent: Join a passionate, multidisciplinary team of AI experts, engineers, and clinicians.
• Opportunity to Grow: We're a startup—there's room for you to grow and lead as we continue to scale
