Hi Guys, we are co-founders of "Petsy" - a marketplace start-up dedicated to dog/cat owners and pet sitters. We just secured a PLN 1m pre-seed financing round for the next 12 months, so we're building the MVP. Right now, we're looking for the Senior Full Stack Developer to join us, with the potential of becoming a future CTO. We seek someone who wants to "blow off steam" technologically and builds something in a way he/she wants, literally from the scratch. We need a Full Stack, our working hypothesis is to use Python & React, but we are open for discussion if you're really good:) and can persuade us to different languages. The concept of start-up itself is validated in the US market - a company Rover.com just went public as a unicorn. In a nutshell, we want to start with a similar concept in Europe, and then expand product-wise to become a "Tamagotchi 2.0" - a one-stop-shop for all the services and products for your pets. For details about this offer please visit Petsy.pl. Cheers!
