Founding Engineer

Reyn is an app that knows a home's whole story and gets anything fixed in a tap, with trusted vendors. Your real estate agent gives it to you at closing. That keeps them in touch and able to help you with your house, and in return they get your repeat business and referrals.

Full-time · Equity + Revenue share · Remote (PST hours)

Overview

Owning a home is overwhelming. We're here to make it simple.

We need a founding engineer to build it with us.

Our product is in production and a brokerage is piloting it right now. One of our advisors is a broker manager who'll help put it in real estate agents' hands across the industry. We sold out our pilot in one hour after we launched it.

You'll receive meaningful equity and revenue share and be able to shape product direction. You have a chance to build something in the emerging category of agentic home care while tapping into two markets that move hundreds of billions a year: real estate referrals and home services.

What we're building

We're building Reyn, an app that helps homeowners and real estate agents be lazier, but get better results.

Homeowners want an easier path to repair something, to take care of the yard, to figure out if it's a good time to make that improvement on their house. They want to know what they should maintain, and they want to not think about it.

The real estate agent wants more business. They want to get the referral they earned, or to keep the client they worked hard to get.

This is what we're building.

The app becomes memory for the home. We turn a pile of messy home data (inspection PDFs, disclosures, warranties, permits, receipts, property records, product recalls) into advice a homeowner can act on, making it easier for them to confidently know what to focus on next, and the network to make it easy.

The role

You'll be the first full-time engineer, working straight with the founder. You'll own engineering for the whole product: the web app where homeowners, real estate agents and brokers do their work, the admin panel our team runs the business from, the marketing site, the Postgres database all three share, and the AI infrastructure (including agentic) that reads home documents and answers homeowners' questions. You'll help us flesh out the web app, then build the mobile app.

You'll own entire areas from idea to deployment, and set the bar for everyone who comes after you. The first three to six months are a grind, you and the founder are finding product-market fit.

After that you choose if you want to grow with the role (own security, privacy, and the vendors and partners we work with, on the path to a real leadership seat) or step back into a lighter seat and keep your revenue share.

Who you are

We're not hiring a staff engineer who's done everything at scale. We're hiring a founder who happens to be an exceptional engineer.

  • Love the craft. You take pride in clean, maintainable code and you sweat the details, because the product carries someone's name and money.
  • Extreme ownership. This is for you if you almost want to start your own thing but aren't quite there yet.
  • Range. You can take a feature from an empty Postgres table to a working screen by yourself, and you've put LLMs into a real product and know how they fail.
  • Taste. You have opinions about what's worth building, not just how to build it.
  • You've shipped your own thing into production and kept it running. You know the pager comes with the territory, and for a while that pager is yours.
  • Use AI well, own the fundamentals. You move fast with AI tools but can explain every line, debug when it breaks, and make the call without waiting for a model to tell you what's right.

Required

  • 5+ years building and shipping production web and mobile applications
  • The ability to have healthy rational debates, and commit to building the best thing for users and the business we're building
  • Deep knowledge of the stack: TypeScript, React, Next.js, Node, Postgres, and the ability to easily use our tools (Supabase, Vercel, Stripe, Resend, Twilio, Gemini, Claude, GitHub, Google Workspace, Notion)
  • Real experience putting LLMs into production
  • Unstructured data processing and relational database design
  • Scheduled and event-driven systems: cron jobs, webhooks, retries, idempotency
  • Extreme comfort with ambiguity

Nice to have

  • An extraordinary ability to build an antifragile product, as well as maintain it
  • Shipped a React Native / Expo app to the App Store and Play Store and kept it alive: EAS builds, OTA updates, push notifications, deep links, and the review-submission gauntlet
  • Real estate, fintech, or proptech background
  • First or only engineer somewhere before
  • Extreme DevOps ownership
  • Bias towards automation
  • Product taste

Current stack

  • The app. Next.js (App Router), React, TypeScript and CSS Modules on Vercel, for homeowners, real estate agents and brokers.
  • The admin panel. React on Vite, with its API in Vercel functions.
  • The marketing site. Next.js, with the blog written in Markdown.
  • Data. One Supabase project shared by all three: Postgres with row-level security, Auth, Storage, Realtime, and cron jobs that run inside Postgres and call our API routes.
  • AI. Google Gemini reads home documents, answers homeowners in Ask Reyn with sources from their own records and Google Search, and powers research in the admin panel. Anthropic's Claude reads appliance labels from photos.
  • Services. Stripe for billing, Resend for email, Twilio for text messages, Google Maps and Places for addresses, and RentCast for property records.
  • Tests. Vitest in the app and the admin panel.

Compensation

This is a founding partnership role. You'll receive highly competitive equity and revenue share.

We're building a lean, hyper-profitable machine. You're taking co-founder risk, so you're getting co-founder upside. You'll get paid directly from the cash flow we generate together.

The founder

Adam Fry-Pierce, formerly at Google, DocuSign, and InVision. He's a power operator from the product and UX side, with 17 years building businesses, programs, and software. He started this company because he got tired of watching people (including himself) buy a home and then make costly mistakes afterward. There's a better way to own and manage a house, and Reyn is the answer.

The binder you get at closing is a poor record. It's unsearchable, hard to add to, easy to lose. Too much guessing. It's time the home had a digital record, one that also helps you figure out what to focus on next.
