Senior Software Engineer, Frontend

About Ruxlo

Linked In is your professional network. Facebook and Instagram are your social networks.

Ruxlo is your Home's Network.

Your Home. Your Neighborhood. Your Town.

Everything a user knows about Ruxlo, they learn through a screen we built. The map, the property profile, the search box, the confirmation flow, the credit meter — that's the product, as far as anyone outside the company is concerned.

You’ll own that layer.

This is a multi-platform role, and that is the whole point. Our mobile apps are Flutter/Dart on iOS and Android; our web app is Next.js/React. We're not looking for someone deep on one who's willing to learn the other — we want an engineer who has genuinely shipped and operated both native-mobile and modern web frontends, and who has the judgment to know what should be shared across them (design language, data contracts, product logic) and what costs more to share than to simply build twice.

You're building at parcel scale, on a map. 150M+ properties, a map-first interface, AI-assisted search that streams its answers, and a freemium meter running underneath. The hard problems here are rendering performance, state, and the honest handling of slow and non-deterministic responses — not CRUD screens.

And SEO is a product requirement, not an afterthought. A profile page for every property in America only compounds if those pages rank — in search engines and increasingly in AI answer engines. Web rendering strategy, structured data, and Core Web Vitals are part of your mandate, not someone else's.

This is a senior IC role building on real foundations, not from zero. There's a monorepo, a web app, and mobile apps already in production. But the component architecture, the shared design system, the rendering and performance bars, and the release process are still yours to set — and the product's appetite is growing faster than any of them. The standards you set early become how Ruxlo does frontend as it scales.

You're hands-on and pragmatic. You'd rather ship a fast, accessible screen than write a framework proposal about one. You care about what the user actually feels — time to first pixel, scroll jank on a three-year-old Android, what happens when the network drops mid-flow — and you use AI-assisted tooling so your time goes to interaction design and performance rather than boilerplate.

• Own the client layer across platforms. Set the component architecture, state model, navigation, and shared design language across the Flutter/Dart apps and the Next.js/React web app — one product, three surfaces, and a frontend strategy other engineers build on.
• Ship the map. The map is the primary interface, not a widget on a page. Own tile and marker rendering, clustering, viewport-driven queries, and the interaction performance that makes 150M+ parcels feel instant.
• Build for search and AI answer engines. Own web rendering strategy — server rendering, incremental static regeneration, structured data, sitemaps — and the Core Web Vitals that decide whether our property pages rank or disappear.
• Make AI features feel good. Streaming responses, honest loading and uncertainty states, optimistic updates, and a credit meter and paywall the user understands. Non-deterministic backends demand interfaces designed for them.
• Own the design system. Partner with Design to turn Figma into tokens and reusable components that hold up across web and mobile, so the product stays coherent as surfaces multiply.
• Own the release trains. App Store and Play review, code signing, staged rollouts, feature flags, forced-upgrade paths, and web continuous delivery — plus the crash and regression response when something slips through.
• Hold the bar on real devices. Performance and accessibility measured on mid-range Android and flaky networks, not on your laptop. You use production signals to catch regressions early.
• Set the standard. Make the build-vs-buy and cross-platform sharing calls, and let the patterns you establish become the team's default.
