Senior Software Engineer (m/f/d)

What Buena Does

Buena (backed by GV) makes everything real estate as simple and transparent as buying an ETF. Whether it's finding, buying, or financing an apartment. We do this by acquiring property managers across Germany and turning them into technology companies.

Throughout the past 2 years we have become Germany's second-largest property manager. We manage 70,000+ units, across 12 locations, and 30+ acquired companies. The property management market is €15+ billion in Germany, fragmented across 22,000 small firms, and 96% still run on pre-cloud software.

We're changing that with currently 22 full-time employees in our HQ.
