In most companies a developer gets a ticket, builds it and moves on to the next one. Someone else talked to the customer, someone else decided what gets built, and whether it actually helped is someone else's question.
We're looking for developers who want to do the whole job: talk to the people who use the software, decide what to build, build it and stay on it until it works for them. That's what we mean by product engineer. We took the term from PostHog, who describe it well in their Product Engineer Handbook .
About us
hausverwalter.ai is software for property management companies in Germany. Inbox, CRM, documents, telephony, video calls, team chat and AI agents in one platform, so property managers can do their daily work in one place. We're a small team based in Worms, Germany, working fully remote. We're self-funded and profitable.
What a product engineer does here
• You talk to customers. You read the support requests and feedback for your area, look at how customers use it and talk to them directly. Nobody filters it for you.
• You decide what to build. For your area you decide what comes next, based on what customers need and what matters for the company. You write down why, so the team can follow and give feedback.
• You ship early. The first version goes to a few customers as soon as it's useful. Then you improve it based on what they say and do.
• You build all of it. Data model, backend, frontend and UI. The result has to be clean, simple and intuitive to use, not only working.
You do support for your area. When something breaks or a customer is stuck, you fix it and tell them it's fixed.
• You check whether it worked. Your job isn't done when the feature is live. You look at whether customers use it and whether it solved their problem.
• You automate what you can. When a customer asks a support question, you add the answer to our knowledge base and update our internal agent, so next time it's handled automatically. A lot already runs on its own here, bug fixes are already processed semi-automatically, and we keep automating more.
Examples of what you could work on
• A customer wants to bring their old file storage into our document management, with their own folder structure and thousands of documents, and it should be fast and AI-supported. You look at how they've organized their files, build the import as a general feature for all customers, set it up for them and test it with their folder structure. Then you check whether the AI assigned every document to the right building, apartment or contact and fix what doesn't fit.
• A customer reports that the inbox agent gave a tenant a wrong answer. You look at what the agent did, fix the tool or its instructions and let the customer know.
• Only a few customers build their own agents in the sandbox. You find out why, by looking at the data and talking to customers, make the setup simpler and check whether more customers use it afterwards.
• Property managers do the same task fifty times a day and it takes too many clicks. You notice it, talk to them about how they work and make it faster.

What we look for
• You care more about whether customers can get their work done than about the perfect implementation.
• You have a good eye for aesthetics and UI design. You don't just ship whatever the AI generates. You keep working on the interface until it's clean and as simple and intuitive as possible for the people using it.
• You finish things. A feature that's 80% done doesn't help anyone, so you stay on it until it works well.
• You have an opinion on what to build and back it up with what customers say and do. When the feedback says otherwise, you change your mind.
• You take feedback well and give honest feedback yourself.
• You write clearly. As a remote team we work a lot in writing: issues, short proposals, PR descriptions.
• You understand the basics of the business: who our customers are, what they pay for and why they stay.
• You write almost all of your code with AI and understand architecture well enough to judge what it writes.
• You'd rather automate a task than do it twice.
• You're a generalist and learn new things quickly.
Nice to have
• You've built your own product or side project that real people used, or you've worked directly with customers before.
• Experience designing databases and optimizing query performance & cost
• Experience building production agents, queues and long-running workflows
This role is not for you if
• you want someone else to decide what you build and hand you tickets
• you'd rather not deal with customers or support
• you want to polish code for weeks before anyone sees it
• you like to move on to the next idea before the last one really works
