(Senior) Fullstack Engineer (w/m/d) (Remote)

Vision and intuition vs. testing and validatingRemember 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.

Where could the Buena journey lead?In the medium and long term, we will expand in all directions: Depth: We will increasingly handle and improve more property management tasks through our software solutions. What started with accounting expanded into AI-enabled ticketing and remote owner’s meetings.Breadth: We will enter new, adjacent business areas—from brokerage to deposit management - all led by productized workflows. Every vertical offers new opportunities to build on a green field and shape our property management operations through software - and you could take the lead.Global: Germany is only our MVP (minimum viable product). While we can become a unicorn (company valued at $1 billion) in the German market alone, we aim to enter the US market. Whoever has conquered Germany can either expand linearly through the EU… or take another leap and go to the US.

Your first week at Buena Mon 9:00 You arrive and receive your Macbook Pro with maxed out specs - and set it up.Mon 9:10 Upon logging into your Buena Email, Slack and Linear you find the Linear onboarding template to get you started. It includes the docs from previous board meetings, our benefits platform (free lunches, 50€ fitness budget/mo, etc.), our VSOP platform (all full-time positions come with equity) and how to get started with the code base.Mon 9:35 While you defer most of the onboarding tasks to a later time, you are now set up and ready to dive into the code. As mentioned above, we don’t believe in preemptive learnings, so Daniel comes by to kick-off your first project. Daniel is an integration manager, he manages six of our portcos (portfolio companies, i.e. property management companies we bought and are now digitalizing) and one of them has had a sophisticated array of templates in their previous software so to onboard them successfully we need to allow them to quickly reply to repetitive emails.

Nikita, one of our senior engineers leads the project and you’ll be working with him.
