Applied AI Scientist presso Pieces

At Pieces, one of our core value statements is that our customer’s mission is a sacred mission… and it's a hard mission. Our hope is to apply advanced AI to make the work of our customers – patient care – easier in as many ways as possible. We use cutting-edge approaches in AI such as agentic AI with clinician-in-the-loop, to help hospitals and healthcare providers reduce documentation and administrative burden, improve communication efficiency, capture revenue, and improve patient outcomes. 

Responsibilities

As an Applied AI Scientist, you will be pivotal in advancing the responsible AI development, deployment, and optimization of our healthcare AI products. The role demands full-stack AI responsibilities and a proactive collaboration with various teams to develop and manage solutions that incorporate a holistic approach to AI system architecture, key generative AI tools, effective data representation, advanced modeling, AI evaluation, adversarial AI strategies, clinical knowledge graphs, and clinician-in-the-loop AI-user interaction. You'll play a vital role in ensuring that our AI systems enhance outcomes for both hospital systems and patients, and uphold our commitment to responsible innovation in healthcare.

Duties and responsibilities include but not limited to:

• Develop the AI evaluation modules under the large language model operations (LLMOps), which includes the components of LLM observability, benchmark datasets, standardization of metrics, evaluation of complex LLM workflow, knowledge graph, etc  

• Implement strategies of AI safety for adversarial detection AI, comprehensive model evaluation, and error analysis, incorporating human feedback for continuous AI model improvement

• Maintain and continuously improve existing data models and AI Engine pipelines, including monitoring performance, resolving production issues, optimizing for scalability, and ensuring robust dataflows across the AI/ML and application stack.

• Apply LLM observability tools, such as LangFuse, Arize Phoenix, Braintrust, etc, for LLM traces, latency and cost awareness, evaluation, and prompt management/deployment.

• Develop data pipelines in AI engine to support a generic data store and data representation, including a meta-data layer for clinical semantics and a vector database for downstream applications

• Develop generative and predictive AI modules and necessary data transformation modules in AI engine alongside agentic AI systems

• Support agentic AI systems development using LangGraph and/or other agentic AI frameworks for the use cases such as AI assistants in both internal applications (e.g. SafeRead) and external ones (e.g. SmarterNotes)

• Collaborate with clinical domain experts and product management teams to translate clinical guidelines into AI modules, ensuring that the developed products align with clinical needs and user requirements.

• Stay updated with the latest AI advancements in the generative AI era, integrating new knowledge into practical applications and contributing to the AI community through professional engagements.

Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.
