AI-Native UI React Engineer (Remote)

Job Description Senior Frontend Engineer (React) – Agentic AI-First Role

• Location: Truckee, CA
• Remote (US-based hours)
• Company: PropertyRadar – hyperlocal lead generation platform for property-centric small businesses (real estate investors, agents, lenders, home services pros). Profitable, owner-operated since 2007.
• Team: Small senior team; direct visibility to VP of Engineering, CEO, and Founder.

Role Overview

Build a delightful UI/UX combining chat-based interactions with rich embedded product experiences. Greenfield frontend work: create a composable React widget framework, reusable data-rich interfaces for property & owner data, and AI-powered features. End-to-end ownership, not a slice.

Why This Is Rare

• Greenfield with revenue backing (profitable 18-year-old business).
• Small team, large surface area – you own delivery end-to-end.
• Real, messy, high-value property and owner data.
• AI-first by mandate – agentic coding is standard, not experiment.

Tech Stack

• React 18, TypeScript, Tailwind, Radix primitives
• Vite (bundler for widgets & host shell)
• OpenAI component kit
• JSON-RPC 2.0 over postMessage for iframe host communication
• Sandboxed iframes with strict CSPs

What You’ll Build

• Composable React widget framework for multiple embedding contexts (sandboxed iframes, web components, shadow DOM)
• Property/owner data experiences: profile views, owner detail panels, interactive maps, lead-gen flows, outreach actions
• AI-powered features within widgets for faster data exploration and lead workflows
• Reusable component library with pixel-perfect UX and accessibility

Expectations (Non-Negotiable)

User Experience

• Make dense, data-heavy interfaces clear via hierarchy, defaults, progressive disclosure, state design.
• Sweat details: empty/loading/error states, interaction polish, accessibility.
• Deep experience with component libraries/design-system engineering.
• Supported customer bases of thousands to millions.

Agentic-Native Development

• Cursor (or Claude Code) is primary IDE, not occasional tool.
• Can describe specific projects where agentic coding changed velocity/quality.
• Opinions on agent orchestration: scoping, breaking up work, reviewing output.
• Bonus: built/contributed to agent workflows, custom Cursor rules, or dev tooling for AI-assisted engineering.

Expert React + TypeScript

• Deep knowledge of React 18, TypeScript, Tailwind, Radix primitives.
• Production Vite experience (libraries/apps).
• Architect complex React frontends; reach for right pattern.
• Built data-heavy UIs at scale (tables, filters, maps, pagination).
• Integrated REST/GraphQL APIs with thoughtful error handling.

Embedding & Iframe Craft

• Experience shipping against sandboxed iframe architectures; understand security model end-to-end.
• Can write/reason about Content Security Policies without docs.
• Implemented structured iframe-host protocols (ideally JSON-RPC 2.0 over postMessage); understand origin checks, message validation, failure modes.
• Familiar with cross-origin behavior, third-party cookie restrictions, practical workarounds.

Ownership & Judgment

• Drive clarity without perfect specs.
• Communicate concisely in writing (remote, async team).

Bonus Points

• Hands-on with OpenAI component kit or comparable embedded-app component libraries (magnet bonus).
• Shipped widgets/embedded apps inside third-party hosts.
• Mapping libraries: Mapbox, Leaflet, Google Maps.
• PropTech, real estate data, or small-business products.
• Owned design system/component platform across multiple products/embedding contexts.
• Experience in AI-first engineering transformation at another company.

How We Work

• Remote-first, async-friendly, US-based hours.
• EOS operating framework – clear quarterly Rocks, weekly accountability.
• Profitable, owner-operated, no VC pressure.
