Senior Software Engineer (m/f/d)

The Senior Software Engineering Role We’re hiring a final core engineering team member to help us rebuild an industry stuck in the early 2000s. Property managers across Germany still run on outdated desktop software with clunky workflows and zero automation. You’ll work closely with our founders and a handpicked team in Berlin to design and build the product this market has never had and always needed. Do not apply if 1. You're looking for a regular job. This is for company builders. 2. You don't want to work from our office in Berlin. 3. You're looking for a large team with established processes. What we're looking for Founder-type talent, matching our intensity, focus on outcomes and excellence. Proven experience in building and shipping production-ready web applications. Strong proficiency in TypeScript, React, and Node.js (or comparable modern stacks). Ability to take features from concept to production independently. Solid understanding of modern web architecture (APIs, state management, data flows). What you'll do Build and ship features end-to-end. Own parts of the product and drive architectural decisions. Improve performance and reliability across our core systems. Work closely with product and design to turn real workflows into simple software. Shape our engineering culture as we grow.
