(Senior) Product Engineer (w/m/d) - Berlin

Vision and intuition vs. testing and validating

Remember when software still felt magical? Good software used to be an experience. It used to radically change how we live and work. It made us feel like we lived in the future.

Today, software is everywhere. But truly great software has become incredibly rare - especially in the real estate industry. Most software at the end of the 90s and has barely updated since. Most software companies in the space make their money not with licenses - but with seminars teaching how to use the software. This leads to an ugly incentive to make software more complicated to sell more seminars.

At Buena we are going back to the essentials that lead to category-defining companies: courageous, first-principled, visionary products. In doing so we step away from the incremental testing-culture that gets all too easily stuck on local maxima.
