The Hartford is seeking aStaff Software Engineer (UI & Applied AI)to join theInnovation Value Streamwithin Personal Lines-an area where engineers helpset the trend for AI platforms across the PL business. This is a rare opportunity to work on agreenfield initiative, shaping how The Hartford designs and delivers nextgeneration AIenabled user experiences. In this role, you will define and build theUI foundation for emerging AI and agentic capabilities, including chat experiences, AI assistant panels (copilots),fileupload for RAG pipelines, agent tools, MCPbased interactions, and integration with API gateways exposing agent ADK runner . You will work directly with acollaborative, productbased teamthat values: • Rapid prototypingto prove ideas early • Enterprise best practicesand alignment with EA and AI governance • Continuous learning and experimentation • Deliveringcuttingedge experiencesthat create measurable value forcrossfunctional Personal Lines users(pricing analysts, CSRs, inspection contractors, underwriting, and product partners) This role offers the opportunity to make asignificant strategic and technical impact, influencing the future of AIdriven application experiences across the Personal Lines organization. Responsibilities • Define and evolve the UI platform strategy, ensuring extensibility, futureproofing, and readiness for rapidly emerging AI capabilities (interact with agent workflows, interactive chat, Agent 2 Agent, agent tool use selection, RAG workflows). • Provide technical leadership, maintaining architectural alignment and the integrity of the UI platform and application environment. • Collaborate with platform teamsto safelyleverage AI and agentic capabilities through stable, versioned APIs and shared governance. • Champion innovation, experimenting with modern frameworks, architectures, and AI-driven enhancements that improve user experience and accelerate delivery. • Partner withProduct, Design, Architecture, Data Science, and Platform teamsto evolve ideas from POCs MVPs scalable production experiences. • Design humanintheloop workflows(approve/override/rollback, review gates, clear status indicators) to ensure safe and transparent AI decision-making. • Planintegration patternsfor GCP Agent SDK/Agent Builder, AWS Bedrock/Anthropic, Snowflake/data products, and retrieval/embedding pipelines using typed SDKs/APIs. • ArchitectAI UX patternssuch as copilots, chat flows, inline recommendations, tool-triggering actions, and tokenstreaming guidance with cancel/retry and partial updates. • Defineprompt templates, guardrails, and explainability signals(confidence, sources, metadata) for safe AI usage directly in the UI flows. • Leadhandson UI developmentin TypeScript using Angular and/or React, delivering modern single-page applications acrossCSR, SSR, and hybrid rendering models (Angular Universal, Next.js). • BuildAI-driven user interaction surfaces:side panels, chats, inline instruction flows, streaming experiences, and contextual tool invocation. • Developfile-upload and documentmanagement interfacesintegrated with RAG pipelines, presenting detailed ingestion lifecycle statuses (uploaded queued extraction embedding retrieval-ready processed). • Integrate UI components withMCP (Model Context Protocol), agent tools, and API gateways, supporting multi-step agent workflows (planning executing tool call validating complete error). • ImproveUI performancethrough modular routing, lazy loading, optimal async patterns, reduced bundle sizes, efficient rendering, and clean component architecture. • Applystrong engineering practices: unit tests, integration tests, E2E, visual regression, prompt regression, and streaming/real-time test harnesses. • Monitor realworld performance and reliability usingDynatrace, Google Analytics, Cloud Logging, and Splunk,ensuring resilience and responsiveness. • Track behavior of AI workflows, tool interactions, streaming performance, and user flows to ensure correctness and minimize latency or failure modes. • Conductcode reviewsfocused on accessibility, maintainability, reliability, and adherence to engineering best practices. • Mentor junior engineers andraise overall engineering craftsmanshipacross the team. • Communicaterisks, issues, decisions, and technical trade-offsproactively to stakeholders and leadership. • Provide ongoing support for platform evolution, architectural governance, and new AI capability onboarding. Qualifications Required • 8+ yearsbuilding complex, production singlepage applications withTypeScript. • Expertise withAngular (v14+) and/or React, including hooks, state management, routing, forms, and component architecture. • Hands-on experience withSSR/CSRpatterns and frameworks (Angular Universal, Next.js). • Hands-on LLM integration:retrieval/embeddings,tool/function calling,streaming responses, andassistant/chat UIs. • Familiarity withMCP, agent tools, andAPI gateways exposing runnables. • Cloud-native experience withGCP and/or AWS; integration withSnowflake/data products, CI/CD pipelines, and feature flags. • Production performance engineering experience: modular routing, lazy loading, async state patterns, bundle control, render efficiency. • Monitoring and observability withDynatrace,Google Analytics,Cloud Logging, andSplunk. • Strong foundational skills in HTML, CSS, JavaScript/TypeScript, REST APIs. Nice to Have • Micro-frontends (Module Federation). • Schema-first API contracts (OpenAPI, GraphQL). • Real-time UX patterns (SSE/WebSockets). • Experience with P&C Insurance workflows (rating, underwriting, CSR, inspections). • Background working with document ingestion pipelines, RAG, or agentic document workflows. Soft Skills & Practices • Excellent analytical, problem-solving, communication, and collaboration skills. • Experience in Agile/Scrum environments. • Curiosity, initiative, and a passion for learning modern technologies and participating in internal communities.
