This role is focused on the development and delivery of our Agentic AI strategy turning architectural blueprints into production-ready systems.
The ideal candidate will be the primary engine for building Python-based AI agents using the Google Cloud (GCP) ecosystem to automate complex claims workflows. You will be responsible for implementing sophisticated LLM behaviors using Gemini.
What you will do:
- Execute Agentic Workflows: Build and deploy sophisticated AI agents using Google Vertex AI and the Google Agent SDK (ADK) based on provided architectural specifications.
- Develop and optimize agent behaviors using Gemini (Pro/Flash) with a focus on reliable tool-calling and multi-step reasoning; implement RAG and grounding strategies to ensure AI agents provide factual data-driven responses derived from internal claims databases and policy documents.
- Design and implement complex system instructions few-shot prompting and Chain-of-Thought reasoning to ensure agents handle claims logic with high precision performing Supervised Fine-Tuning on Gemini models to improve domain-specific performance in adjudication and medical coding
- Data & Messaging: Expert in SQL/PostgreSQ/AlloyDB/BigQueryUnderstand architectural decisions and actively drive reusable patterns for cloud-native AI-enabled backend systems.
- Design and implement Stateful Orchestration patterns that incorporate human review breakpoints ensuring agents can pause persist state and resume workflows after auditor approval.
