Full Job Description
Commerce is building a new team to deliver a suite of conversational AI agents spanning the B2B commerce lifecycle - Product Discovery, Pricing & Quoting, Order Automation, Fulfillment & Delivery, and Post-Sale Support. These agents will let B2B buyers and sellers work through complex commerce workflows in natural language, built on an established internal agent platform (Go/Python, Google ADK, Gemini, AG-UI, Braintrust). As the Senior Frontend Engineer on this team, you will own the unified agent frontend: a single streaming, generative-UI experience through which merchants and buyers interact with all five agents. This is a greenfield product built on proven platform patterns - you'll shape the user-facing surface of an entirely new product line. What You'll Do
  • Design and build the unified agent frontend, delivering real-time streaming conversational experiences over SSE (AG-UI protocol)
  • Build and extend a library of generative UI components (product cards, cart and order summaries, quote views, escalation flows) rendered dynamically from agent output
  • Deliver the merchant-facing control panel settings and shopper-facing views for the agent suite
  • Own frontend architecture decisions: component structure, state management for streaming data, theming and embedding strategies across storefront environments
  • Collaborate closely with backend agent engineers on the client9server event protocol and client-executed tools
  • Partner with product and design to deliver intuitive, useful, and delightful conversational experiences
  • Quickly build proof-of-concept solutions to validate user stories, then harden them for GA
  • Mentor other engineers and raise the bar on frontend quality across the team
Who Are You
  • 5+ years of frontend or full-stack software development experience
  • Education: Preferred minimum Bachelor's degree in CS, EE, SW, CE, MIS; or equivalent experience
  • Expert-level Javascript skills
  • Experience building real-time or streaming UIs (SSE, WebSockets) and managing the state challenges they create
  • Experience building conversational or AI-assistant UIs (chat, generative UI, copilots)
  • Strong product sense and demonstrated ability to own a user-facing surface end-to-end
  • Experience integrating frontends with complex backend APIs
  • Excellent problem-solving skills and comfort in a fast-paced, exploratory environment
  • Strong collaboration and communication skills in cross-functional teams
  • Strong preference toward execution and delivery
Preferred:
  • Experience with e-commerce platforms or SaaS product development
  • Familiarity with design systems and embedding UIs into third-party or themed environments
  • Exposure to LLM-based products and their frontend patterns (token streaming, tool-call rendering, approval flows
  • Experience with automation tools or AI copilots
