AI-Native UI React Engineer

Read this first We are betting the engineering org on agentic coding. Our team has already made the transition. Cursor is our primary development environment, and we hire engineers who orchestrate AI agents to ship at multiples of traditional velocity — not engineers who use AI to autocomplete the occasional function. We use agentic coding to ship faster, but the bar is not speed alone — it’s turning complex data into experiences that feel obvious, elegant, and useful. If “I use Cursor for everything now” describes you, keep reading. If you are still warming up to agentic workflows, this isn’t the role. About PropertyRadar PropertyRadar is the hyperlocal lead generation platform that property-centric small businesses use to discover, understand, and connect with new opportunities. We turn complex public records data into actionable insights for real estate investors, agents, lenders, and home services pros. We’ve been doing this since 2007. We’re profitable, owner-operated, and small enough that what you ship matters — every release moves the business. We’re investing in a modern data and frontend platform to power the next decade of growth, and we’re hiring engineers who can help us build it. The role You will build a UI/UX that delights end users by combining chat-based interactions with rich, embedded product experiences. The bar is a highly intuitive experience that keeps users focused on their goals instead of forcing them to stop and learn how PropertyRadar works. You’ll create the composable React widget framework and reusable, data-rich interfaces that bring PropertyRadar’s property and owner data into new contexts. This is greenfield frontend work with direct visibility to the VP of Engineering, CEO, and Founder, and you’ll work closely with all three on scope and tradeoffs. Why this is a rare role Greenfield, with revenue behind it. You get the blank slate of a startup with the distribution and cash flow of an 18-year-old profitable business. Small team, large surface area. You own end-to-end delivery, not a slice of a slice. Real users, real data. Property and owner data is one of the richest, messiest, most useful datasets in the small-business economy. You’ll build the user experience of making this messy, high-value data feel intuitive and actionable. AI-first by mandate. You’re joining an engineering culture where agentic coding is the standard, not the experiment. The stack React 18, TypeScript, Tailwind, Radix primitives Vite as the bundler for both widgets and the host shell OpenAI component kit JSON-RPC 2.0 over for iframe ↔ host communication, following emerging AI-host bridge standards Sandboxed iframes with strict CSPs and well-understood cross-origin behavior What you’ll build A composable React widget framework designed to run across multiple embedding contexts — sandboxed iframes, web components, shadow DOM — with a consistent component model and clean developer ergonomics. Property and owner data experiences: profile views, owner detail panels, interactive maps, lead-gen flows, and outreach actions, all designed to be embedded and reused. AI-powered features within the widgets, integrating LLM capabilities to make data exploration and lead workflows faster and more intuitive. A reusable component library with strong UX, pixel-accurate polish, and accessibility built in. What we expect of you Bring product taste and craft. You care about the difference between “it works” and “this feels great to use,” and you can implement at a pixel level. Ship at agentic-native velocity. We’re hiring engineers who deliver materially faster than traditional React teams because Cursor (and other agentic tools) are the primary way they work. Own the spec. Ask sharp clarifying questions, make sound tradeoffs, and ship. We don’t hand you tickets. Raise the team’s ceiling. Share patterns, prompts, and orchestration techniques that make everyone faster. About you — non-negotiable User Experience You know how to make dense, data-heavy interfaces feel clear through hierarchy, defaults, progressive disclosure, and state design. You sweat the details: empty states, loading states, error states, interaction polish, and accessibility are part of the product, not cleanup work. You bring deep experience with component libraries and/or design-system engineering, with a strong eye for consistency, usability, and polish. You've supported customer bases of thousands to millions. Agentic-native development Cursor (or Claude Code) is your primary IDE — not a tool you reach for occasionally. You can describe specific recent projects where agentic coding meaningfully changed your output velocity and quality — with examples. You have opinions on agent orchestration: how to scope work for agents, when to break it up, how to review agent output, when to step in manually. Bonus: you’ve built or contributed to agent workflows, custom Cursor rules, or developer tooling for AI-assisted engineering. Expert React + TypeScript Deep working knowledge of React 18, TypeScript, Tailwind, and Radix primitives. Production experience with Vite as a build tool for libraries, applications, or both. You architect complex React frontends comfortably and reach for the right pattern, not the familiar one. You’ve built data-heavy UIs at scale — complex tables, filters, maps, sorting, pagination — and you know how to make them performant. You’ve integrated REST and GraphQL APIs with thoughtful loading, error, and edge-case handling. Embedding and iframe craft You’ve built or shipped against sandboxed iframe architectures and understand the security model end-to-end. You can write and reason about Content Security Policies without reaching for documentation. You’ve implemented protocols between iframe and host — ideally JSON-RPC 2.0 over or a similar structured pattern — and you understand origin checks, message validation, and the failure modes. Cross-origin behavior, third-party cookie restrictions, and the practical workarounds for embedded apps are familiar territory. Ownership and judgment You don’t wait for perfect specs. You drive clarity. You communicate concisely in writing — important on a remote, async team. Bonus points Hands-on experience with the OpenAI component kit, or comparable embedded-app component libraries. This is a magnet bonus. You’ve shipped widgets or embedded apps that run inside a third-party host environment. Mapping libraries: Mapbox, Leaflet, Google Maps. PropTech, real estate data, or products built for small businesses. You've owned a design system or component platform used across multiple products or embedding contexts. You’ve already been through an AI-first eng transformation at another company — you can help us avoid mistakes. How we work Remote-first, async-friendly, US-based hours. Small senior team — direct access to VP of Engineering, CEO, and Founder on this initiative. EOS as our operating framework — clear quarterly Rocks, weekly accountability, no surprise priorities. Profitable, owner-operated, no VC pressure. We move fast because we choose to, not because a clock is ticking. Apply To This Job
