The Senior Full-Stack Engineer, AI Platform is a peer-level technical contributor who owns the complete product surface: from React and Angular UI components through NestJS service modules to Python FastAPI route handlers. This individual operates as a primary engineer across all four repositories, participates in architectural decision-making, and upholds the quality standards of the Crucible SDLC framework. The role is hands-on and delivery-focused — the expectation is production-grade code shipped on schedule, sprint over sprint. ### Key Responsibilities Frontend Architect and deliver React applications as the primary frontend framework for new products, from initial project setup through production deployment - Maintain and extend the existing Angular 17 application — standalone components, reactive forms, RxJS streams, and Angular Material component library - Build performant, accessible user interfaces that surface AI outputs: streaming chat and RAG response displays, document upload and processing status, and structured data visualization - Integrate frontend applications with NestJS and FastAPI backends via REST APIs, Server-Sent Events (SSE) for streaming AI responses, and multipart file upload pipelines Author unit, component, and integration tests across React (Jest) and Angular (Karma/Jasmine) contexts, maintaining meaningful coverage without being directed to do so Instrument frontend applications with Azure Application Insights; own frontend observability, error tracking, and performance monitoring Backend — NestJS Middleware - Design and implement feature modules in the NestJS middleware layer: DTOs, controllers, services, and providers following established module patterns Integrate Azure Cosmos DB, enforce JWT authentication guards, and instrument all new code with OpenTelemetry distributed tracing Author and maintain Swagger/OpenAPI documentation for all new and modified endpoints - Apply parameterized Cosmos DB queries and structured Ogma logging consistently across all contributions Backend — Python FastAPI Contribute production-ready route handlers, Pydantic models, and async service logic to the RAG orchestration service and the doc-parser-api document processing pipeline - Implement and extend Azure AI Search integrations, embedding pipelines, and document ingestion workflows - Execute quality gates on all Python contributions: ruff linting, mypy static type checking, pytest with a minimum 80% coverage threshold, and bandit security scanning Cross-Cutting - Participate in code reviews across all four repositories; provide substantive technical feedback and uphold Conventional Commits and Semantic Versioning standards Leverage agentic coding tools — Claude Code, GitHub Copilot, and their successors — as daily productivity multipliers within a disciplined engineering workflow - Collaborate with AI/ML engineers, UX designers, and product managers to translate complex AI capabilities into intuitive, production-ready user experiences - Contribute to architectural decisions spanning state management patterns, API contract design, CI/CD pipeline configuration, and cross-repo dependency management ## Qualifications ### Required Qualifications 7–10 years of professional software engineering experience delivering production systems at meaningful scale React — deep proficiency with hooks, context, and state management libraries (Redux, Zustand, or equivalent); demonstrated ownership of a React codebase from inception through production TypeScript — rigorous typing discipline in both frontend and Node.js backend contexts; strong preference for candidates who leverage the type system rather than work around it NestJS or an equivalent Node.js backend framework (Express, Fastify) — experience designing RESTful services, middleware, and modular application architecture Python — comfortable authoring production-grade FastAPI services with Pydantic data models and async route handlers Azure ecosystem — practical experience with managed identity (DefaultAzureCredential), Key Vault, Cosmos DB, Blob Storage, and Application Insights Async data patterns — REST, Server-Sent Events, streaming responses, and observable/promise-based data flow across frontend and backend contexts Testing discipline across the full stack — Jest, Karma/Jasmine, and pytest; writes tests as an intrinsic part of delivery, not a post-hoc addition Git workflow fluency — feature branching, pull request workflows, code review participation, and CI/CD integration Proven delivery track record — demonstrable history of shipping features into production environments on schedule ### Nice to Have Angular 17+ — standalone components, RxJS, Angular Material, and route guards Azure AI Search, OpenAI API, or hands-on experience designing RAG architectures Agentic coding assistants — Claude Code, GitHub Copilot, or equivalent tools used as a genuine workflow accelerant OpenTelemetry instrumentation — distributed tracing across polyglot service boundaries AI-adjacent UI patterns — LLM streaming interfaces, markdown rendering, document viewers, and file processing pipelines Regulated industry exposure — insurance, financial services, or healthcare environments where compliance and auditability shape engineering decisions Open-source contributions demonstrating depth of craft Chubb Canada does not use artificial intelligence (AI) tools to assess, screen, or select applicants.
