The Claims team is evolving from traditional rule-based adjudication to an intelligence-driven platform. We are seeking a Lead Software Engineer who excels at high-level technical execution. This role focuses 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.

• 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/Postgre
  
  SQL/Alloy
  
  DB/Big Query and experienced in managing high-throughput data via Kafka.
• Understand architectural decisions and actively drive reusable patterns for cloud-native, AI-enabled backend systems.

• Expert Python Developer:
  Exceptional skills in building production-grade applications using frameworks like Lang Chain, Lang Graph, or Pydantic
  
  AI.
• 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, Wind Surf, Git Hub 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, Lang Chain.
• Existing Backend:
  Java, Spring Cloud, Spring Boot.
• Data & Messaging:
  Postgre
  
  SQL, Kafka, Spark, Alloy
  
  DB, Big Query
• Infrastructure: GCP (Vertex AI, GKE, Cloud Run), Kubernetes, Docker.
