🇩🇪 Fullstack-Developer (100% Remote / German-Speaking)

Fluent German is required for this role. Our customers are property management companies in Germany.

We're looking for Junior and Senior Developers for our fully remote team who want to be responsible for a part of the product: talking to the property managers who use it, deciding what to build next and making sure it works for them.

About Us

Hausverwalter.ai is an all-in-one platform for property management companies with features like an Inbox, CRM, Documents, Telephony, Video Calls, Team Chat and AI-Agents. We want to automate as much of a property manager's daily work as we can.

What you'll do

You'll build with Claude and work on your own area of the product. Which one depends on where you fit best. Our work splits roughly like this:

• Product (Full-Stack). Work on the software property managers use all day. Talk to them about where they lose time, decide what to improve, own new features and refine them until they're as easy to use as the Uber app.

• Integrations (Backend). Handle every way data gets into our platform. Email, phone calls (Twilio & Vonage), WhatsApp. The other half is moving customers off whatever they used before. You work on this directly with the customer: importing years of email, hundreds of thousands of documents, and every record on their buildings, apartments, contracts and contacts, plus syncing with systems a customer still runs alongside us.

• Agents (Backend). Improve the agent platform behind hausverwalter.ai with 200+ tools and a built-in knowledge base. Customers build and train their own agents in a sandbox or use agents we've already built for them. Both text and voice. When an agent gets something wrong for a customer, you find out why and fix it.

Our minimalistic tech stack

Everything is TypeScript. From our database schema to the frontend.

Backend: Convex (Database & serverless functions)

Frontend: Next.js, React, Tailwind, shadcn/ui

For a closer look at what we're building, check out our YouTube channel — heads up, it's in German.

You are:

• fluent in German and English.

• a seasoned developer with more than a year of experience shipping production code

• a builder first. You'd rather get the first iteration of a feature in front of fifty customers than spend three weeks fretting over a perfect PR. You ship.

• used to working independently and taking full responsibility for your area, also after it goes live.

• writing almost all of your code with AI.

• comfortable talking to customers and turning what they tell you into product decisions.

• quick to learn new things and consider yourself a generalist, not a specialist.

Your techstack:

is not important to us, since AI will be writing 100% of your code.

Nice to have:

• Solid backend and systems-design experience – experience designing a database from the ground up (tables, relationships, indexes) and also with optimizing query performance & cost

• Experience building production agents

• Comfort with queues and long-running workflows
