Senior Backend-Developer / AI-Developer 100% Remote

We're seeking experienced Backend or Fullstack Developers with a strong systems-design mindset to join our fully remote team. If you like complexity, enjoy thinking hard about data, scale and reliability, want to implement AI-solutions and enjoy working with Claude/Cursor/Codex, this could be the right role for you.

Our product

You'll be working on hausverwalter.ai – our AI-first, all-in-one platform for German property management companies, which enables customers to set up, train and measure AI agents to automate any task they want. It is an ambitious project consisting of modules for ticketing, project-management, documents, knowledgebase & team-communication. Currently property managers use on average 5-10 software tools daily. We are building a single software to replace (and automate) them all.

What you'll do

• Develop and maintain our web application

• Design and own our data layer – schema and table design, relationships and indexing, and query/load optimization that holds up as the system grows

• Design queues, background jobs and long-running workflows that stay correct and reliable under heavy load

• Contribute to architecture decisions, the direction of our stack, and the overall product vision

• Build robust pipelines for document- & email processing and 3rd-party-integrations that handle volume spikes gracefully

• Build and optimize agents for our growing template-library

• Extend our RAG / knowledge base system (embeddings, semantic search, reranking)

• Operate in an AI-first development setup powered by Claude/Cursor

• Manage version control and team collaboration via GitHub

Our techstack

• Backend: TypeScript

• Frontend: Nextjs, React, Tailwind, shadcn/ui

• Database: We don't want to disclose this publicly at the moment

What we're looking for

• Solid backend and systems-design experience – you can design a database from the ground up (tables, relationships, indexes) and reason about database load, query performance and data growth, not just write CRUD against an existing schema

• Comfort with queues, background jobs and long-running workflows, and the judgment to make the hard design trade-offs they involve

• You treat reliability, scalability and maintainability as default concerns. If you've read "Designing Data-Intensive Applications" (Kleppmann) – or simply think that way – you'll feel right at home here

• AI-first mindset – make use of multiple Claude / Cursor / Codex subscriptions depending on your needs

• A software that our customers are genuinely excited about

• Modern tech stack – you'll work exclusively with cutting-edge technologies

• Fokus on building, instead of long meetings
