Google Cloud Principal Architect - GenEMR; AI & Cloud

The Project

We are embarking on an ambitious journey to redefine healthcare technology by building a "Gen3" Electronic Medical Record (EMR) system. Moving beyond traditional monolithic systems, this next-generation platform will be cloud-native, event-driven, and fundamentally infused with Generative AI to drastically reduce clinical burden and unlock unprecedented data insights.

As the Principal Architect for the Gen3 EMR, you will act as the technical nucleus of the initiative. Your primary focus will be the rigorous discovery of existing application landscapes and defining the architectural blueprint for the new system. You will champion the integration of advanced AI workloads using an Anthropic/Lang Chain stack into a highly scalable microservices environment.

This is a highly visible leadership role requiring a balance of deep technical expertise in modern AI/Cloud architectures and exceptional communication skills to manage stakeholder expectations and produce definitive technical documentation.

Application Discovery & Strategic Roadmap (Primary Focus)

• Lead comprehensive technical due diligence and application discovery phases to understand legacy workflows and data models.
• Define the transition strategy from current state to a target "Gen3" state based on microservices, event-driven architecture (EDA), and serverless principles.
• Create detailed architectural blueprints, system interaction diagrams (Plant
  
  UML), and whiteboards (Miro) to communicate the vision.
• Design and act as the Technical Lead for the platform’s AI capabilities, moving beyond simple API calls to complex, stateful AI agents.
• Architect solutions utilizing Anthropic Claude models tailored for clinical data processing.
• Define the standards for LLM orchestration using Lang Chain and complex agentic flows using Lang Graph
  .
• Implement robust observability, evaluation, and tracing for AI workflows using Lang Smith
  .
• Design the retrieval architecture (RAG), integrating vector databases like Qdrant with relational data (Postgre
  
  SQL) for context‑aware AI outputs.

Core Architecture & Google Cloud Platform Cloud Leadership

• Architect the infrastructure on Google Cloud Platform
  , specifically focusing on GCP LZA Design, GCP Networking and Integration, Security and Governance.
• Define the standards for a polyglot microservices backend, leveraging Java for core transactional services and Python for data/AI services.
• Design high-throughput, asynchronous data backbones using Apache Kafka for real‑time event streaming across the EMR.

Technical Governance, Reporting & Communication

• Serve as the primary technical point of contact for executive leadership and project stakeholders.
• Translate complex architectural decisions into clear business value propositions through regular technical reporting.
• Maintain rigorous technical documentation and architectural decision records (ADRs).

Technical Mentorship & Team Enablement

• Provide high‑level guidance to Frontend teams, ensuring the React/Type Script/Vite architecture aligns with backend APIs and AI capability exposure.
• Steer Backend teams on service boundaries, API contracts, and data access patterns.
• Drive the adoption of modern development tools, including AI‑assisted coding (Cursor, VS Code) to accelerate development velocity.

Must‑Have Technical Experience

• 15+ years of software engineering experience with 5+ years in a Principal or Chief Architect role handling enterprise‑scale distributed systems.
• Proven track record in Application Discovery: Experience analyzing legacy systems and defining modernization strategies for complex domains.
• Deep GCP Expertise: Demonstrable experience architecting cloud‑native solutions on Google Cloud, particularly GKE.
• Production AI/LLM
  
  Experience:
  
  Hands‑on experience architecting GenAI solutions using the Lang Chain ecosystem (Lang Chain, Lang Graph, Lang Smith) and integrating LLMs like Claude
  .
• Experience with vector databases such as Qdrant
  , Pinecone, or Weaviate in a RAG context.
• Strong background in event‑driven architecture using Apache Kafka
  .
• Expertise in designing polyglot microservices environments (Java and Python preferred).
