Senior AI Software Engineer

City National Bank of Florida is seeking a hands-on Senior AI Software Engineer to architect, develop, and deploy secure, scalable, production-grade AI applications and agentic workflows. This role is focused on Python-based backend services, LangGraph and LangChain orchestration, and enterprise RAG implementations on Azure with an emphasis on production operations.

Responsibilities

• Design and implement production-grade AI applications and backend services using Python, FastAPI, and modern engineering practices.
• Lead technical implementation of stateful, multi-step agentic workflows using LangGraph and LangChain v1.
• Implement graph state management and workflow controls including conditional routing, checkpointing, retries, recovery, idempotency, and controlled execution.
• Build enterprise RAG architectures covering ingestion, chunking, embeddings, Azure AI Search, hybrid retrieval, reranking, metadata filtering, and source-grounded generation.
• Integrate Azure OpenAI, enterprise APIs, document repositories, databases, and internal systems using secure API contracts.
• Design and implement MCP servers and tools, including authentication, authorization, input validation, and appropriate access controls.
• Create reusable application components, API interfaces, shared libraries, and common AI engineering patterns.
• Implement human-in-the-loop approval gates, workflow state persistence, audit trails, and safeguards to prevent unauthorized downstream actions.
• Establish automated quality gates for unit testing, integration testing, retrieval evaluation, agent behavior, security, and regression testing.
• Engineer for reliability, scalability, latency, cost, observability, and maintainability.
• Implement secure cloud application patterns using Azure identity, managed identities, Key Vault, network controls, and secrets management.
• Containerize and deploy services via CI/CD pipelines to Azure Container Apps (ACA), using Azure Kubernetes Service (AKS) where workload requirements justify it.
• Integrate Azure Monitor and application telemetry for logs, metrics, tracing, incident investigation, and operational support.
• Review code, guide implementation decisions, troubleshoot complex production issues, and mentor other engineers while remaining an active developer.
• Partner with AI leadership, application teams, architecture, cybersecurity, model risk, legal, and business stakeholders to deliver governed banking AI solutions.

Requirements

• Approximately 8 years of professional software engineering experience, including substantial hands-on Python development.
• Strong understanding of software architecture, design patterns, SOLID principles, concurrency, asynchronous programming, API design, and distributed systems.
• Experience with FastAPI (or equivalent), Pydantic, SQL, Git, pytest, and automated code-quality practices.
• Demonstrated ability to design, implement, test, deploy, and troubleshoot production services.
• Hands-on experience delivering LLM-powered applications beyond proof-of-concept.
• Practical knowledge of LangGraph and LangChain (direct LangGraph experience strongly preferred).
• Experience with stateful workflows, tool calling, conditional execution, structured outputs, retries, failure recovery, and human approval patterns.
• Strong knowledge of end-to-end RAG, embeddings, vector and hybrid search, reranking, grounding, and retrieval evaluation.
• Experience designing repeatable LLM evaluation and regression-testing strategies.
• Ability to diagnose hallucinations, retrieval failures, prompt-injection risks, tool misuse, and inconsistent agent behavior.
• Hands-on experience with Azure OpenAI and preferably Azure AI Search.
• Experience with Azure identity and security services, including managed identities and Key Vault.
• Experience with Docker, CI/CD, cloud deployments, automated testing, monitoring, and production troubleshooting.
• Experience building secure APIs and integrating enterprise systems.
• Strong understanding of authentication, authorization, least privilege, data protection, and auditability.

Technologies

• Python, FastAPI, LangGraph, LangChain v1, Azure OpenAI, Azure AI Search, MCP
• Pydantic, SQL, Git, pytest, Docker, CI/CD
• Azure Container Apps (ACA), Azure Kubernetes Service (AKS)
• Azure Monitor, Azure identity, managed identities, Key Vault, Azure Database for PostgreSQL, PostgreSQL
• OpenTelemetry

Preferred Qualifications

• Production experience implementing MCP servers and secure enterprise tools.
• Experience with Azure Container Apps and Azure Kubernetes Service.
• Experience with PostgreSQL or Azure Database for PostgreSQL, persistent workflow state, and object storage.
• Experience with enterprise document processing and financial data extraction.
• Experience with OpenTelemetry, distributed tracing, AI observability, latency optimization, and token-cost management.
• Banking or other regulated-industry experience, especially credit, lending, fraud, or risk workflows.
• Experience with model governance, explainability, human oversight, and responsible AI practices.
