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, ensuring agents are grounded in claims data, and maintaining our existing Java/Spring Cloud microservices.
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
- Dual-Stack Support: Act as a lead developer for the claims pod, balancing Python-first AI development with the maintenance and extension of our Java/Spring Cloud microservices.
- Data & Messaging: Expert in SQL/PostgreSQ/AlloyDB/BigQuery and experienced in managing high-throughput data via Kafka.

- Expert Python Developer: Exceptional skills in building production-grade applications using frameworks like LangChain, LangGraph, or PydanticAI.
- Gemini & Vertex AI: Hands-on experience building with the Gemini model family and the Google Agent SDK (ADK).
- Prompt Engineering: Proven ability to engineer high-performance prompts that mitigate hallucinations and ensure deterministic outputs in regulated environments.
- 8+ years of Full-Stack experience with a heavy focus on backend systems.
- Java Proficiency: Strong working knowledge of Java and Spring Cloud, capable of supporting and extending existing microservice architectures.
- AI-First SDLC: Mastery of AI-enhanced development tools (e.g., Cursor, WindSurf, GitHub Copilot) to drive team velocity.
- Healthcare Data: Familiarity with healthcare interoperability standards and claims-related data structures.
- Fine-Tuning Expertise: Practical experience in fine-tuning LLMs for specific industry nomenclature or structured output formats.
- AI & LLMs: Gemini, Vertex AI, Google ADK, Python, LangChain.
- Existing Backend: Java, Spring Cloud, Spring Boot.
- Data & Messaging: PostgreSQL, Kafka, Spark, AlloyDB, BigQuery
- Infrastructure: GCP (Vertex AI, GKE, Cloud Run), Kubernetes, Docker.
