We are a fungible mix of front-end, back-end, and ML/AI engineers driving higher customer conversion through AI-powered onboarding, building a suite of AI capabilities into our consoles — LLM agents, personalization, recommendations, and experimentation — and unifying our platform at the architectural level. On the front end, that means rendering streamed agent responses and tool-call progress in real time, designing human-in-the-loop confirmation flows for agents that act on a customer's behalf, building bounded-choice wizards that collapse a dozen decisions into one guided path, and instrumenting conversion funnels and A/B experiments so we can prove each change is better for customers. Our consoles are built in TypeScript and React on Cloudscape (the AWS design system) and are moving toward a federated console architecture.
At Amazon, we hire the best minds in technology to innovate and build on behalf of our customers. As a Front End Engineer II, you'll own features end to end — from UX collaboration and design through implementation, testing, launch, and operation — on surfaces that directly move customer conversion. You'll work alongside senior engineers on the harder, more ambiguous problems, participate in design and code reviews, and partner with UX designers, applied scientists, and backend engineers to bring agentic experiences to customers. Because the harness is a multi-product platform, what you build is reused by every team shipping AI experiences on it.
Key job responsibilities
Build the conversational and agentic wizard surfaces of the harness — streaming chat UI, tool-call and progress rendering, result cards, and human-in-the-loop confirmation and hand-off flows — in TypeScript/React on Cloudscape in the WorkSpaces Console.
Build guided onboarding and provisioning experiences (Quick Setup, Create WorkSpace, catalog management) where the agent recommends and the customer confirms, with clear paths back to the full console for everything else.
Instrument the customer journey end to end — feedback capture, recommendation acceptance, funnel events — and build the front-end side of our A/B experimentation, so agent quality and conversion are measured, not guessed.
Help define the front-end contract with the harness backend: typed interfaces for agent responses, tool results, and streaming, co-designed with backend engineers so new expert agents render correctly without bespoke UI work.
Deliver accessible (WCAG), localized, and performant experiences — streaming latency, bundle size, perceived responsiveness — and share in operational excellence for the console surfaces (availability, client-side error monitoring, on-call readiness).
Contribute reusable components and patterns to the shared platform and to our federated console architecture so product teams can build agentic surfaces consistently.
Write well-tested, maintainable code; participate in design and code reviews; and help onboard new engineers and interns.
A day in the life
You might spend the morning building the streaming response renderer for a new expert agent and wiring its confirmation step, pair with a UX designer at midday to iterate on the Create WorkSpace recommendation card against customer feedback, and in the afternoon add funnel instrumentation and read out an A/B experiment with an applied scientist — then ship it behind a feature flag. You'll operate in an agile environment where development cycles are measured in weeks, see your work reach customers quickly, and learn from senior engineers tackling the hardest parts of the platform.
WorkSpaces Forefront owns the admin experience across the WorkSpaces Consoles (Personal, Applications) and the WorkSpaces SDK. We're building an agentic control plane for Console and programmatic experiences — an agentic harness (LLM agents, routing, ranking, personalization, memory, knowledge bases, MCP tools, and evaluation) plus experimentation and closed-loop learning — while unifying key infrastructure toward a federated console architecture.
