Senior Software Engineer, AI

Role Description

Our client is a pioneering, seed-stage startup on a mission to revolutionize the delivery of pharmacy care worldwide. They build a category-creating product suite of proprietary LLMs, AI agents, and cloud tools that empower pharmacists to focus entirely on patient care and remedy the unsustainable situation of chronic pharmacy understaffing in a world of aging populations and declining graduation rates.

The client’s product suite leverages AI, particularly LLMs and intelligent search, to deliver context-aware clinical decision support in the pharmacy setting. It effectively acts as an on-demand clinical assistant, helping pharmacists quickly navigate vast amounts of drug information and patient data. External observers have described the company as a “developer of AI infrastructure for pharmacy and life science companies” that provides powerful contextual search through millions of documents within seconds. This capability enables pharmacists to obtain precise answers and insights rapidly, thereby improving both efficiency and the quality of patient care.

Key Responsibilities

• Machine learning engineering: Design, train and fine-tune LLMs for pharmacy-specific tasks, and build and maintain the integration layers that connect these models to external systems such as REST APIs and vector databases for reliable, production-grade data retrieval and inference.
• Data pipeline engineering: Build and optimize scalable pipelines that ingest unstructured medical data, apply OCR, cleaning, and normalization steps, and transform the results into standardized, high-quality datasets for both model training and real-time inference while ensuring scalability, accuracy, and regulatory compliance.
• Backend software development: Write, test, and maintain scalable backend services and APIs using Python (FastAPI) and TypeScript (Node.js), ensuring clean, maintainable code, robust testing, and seamless integration with the AI platform.
• Cloud infrastructure & DevOps: Manage and optimize deployments on GCP, containerize applications with Docker, and orchestrate Kubernetes clusters to ensure reliable, scalable, and secure infrastructure.
• Customer collaboration: Engage directly with pharmacy partners and clinical stakeholders to gather feedback, diagnose real-world workflow challenges, and ensure development cycles deliver maximum value for customers.

Tech Stack

• Back-end & APIs: Python (FastAPI), TypeScript (Node.js), Vector databases
• Machine Learning: PyTorch; Retrieval-Augmented Generation (RAG) pipelines; LLM fine-tuning
