As a Staff Applied Scientist, you will play a crucial role in developing, improving, and exploring the capabilities of multimodal LLMs to solve complex real-world problems geared towards building automation and Conversational AI products enabling increased productivity and magical experiences for our customers.

The ideal candidate should be passionate about applying AI/ML science to difficult problems and develop scalable customized solutions. We want people who like working in a collaborative team environment and enjoy creating practical, efficient, and high-performance software that leverages Large Language Models (LLM), Multimodal Language Models(MLM), and other ML models and techniques to build amazing capabilities for our customers, partners, and employees. Most importantly, we are a mission-oriented, high-growth startup, and we are looking for folks that are excited to be part of our journey to make lasting impact towards transforming healthcare.

Responsibilities:

• Investigate the latest LLM MLM models and evaluate and compare accuracy and efficiency for our in-domain use cases.

• Collaborate with product managers, engineers, and other stakeholders as a specialist and subject matter expert in Artificial Intelligence and Machine Learning science.

• Develop tools and processes to create data pipelines for ML training and customization

• Finetune LLMs for the healthcare domain on our data.

• Help develop and productionize machine learning (ML) solutions leveraging our customized models in the fields of Document understanding, Search and QnA, GenAI, Virtual Agents, etc.

• Work across the complete lifecycle of ML model development, including problem definition, data exploration, feature engineering, model training, validation, and deployment.

• Participate in code reviews, testing, and quality assurance processes.

• Troubleshoot and resolve technical issues related to AI model, integration, deployment and backend services.

• Document and communicate research and development processes, and architectural decisions.

• Ensure the security and compliance of healthcare data, adhering to HIPAA regulations.

• Solve technical problems of the highest scope and complexity for the team.

• Exert influence on the overall objectives and long-range goals of the team.
