Buena's Mission Buena makes 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 third-largest property manager with less than 25 full-time team members at our HQ.

The Product Engineering Role We’re hiring a final core product 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 Property managers across Germany still run on outdated desktop software with clunky workflows and zero automation.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 won’t just build features, you’ll deeply understand user problems, design better systems, and ship solutions end-to-end. You’ll work closely with our founders and a handpicked team in Berlin to define, build and iterate on the product this market has never had, but always needed.
