If you are a Senior Front-End Developer, who is motivated, who wants to learn and to have a vote on how things are done, this is your chance to get it. 

But it will not come without responsibilities, you will have to find solutions to make our applications efficient, good looking and stable. You will have the chance to decide but also the responsibility of doing it well. You will also have to mentor others and to be open to listen other's opinions.

We want someone who's willing to constantly learn and improve, someone who will support our project(s) and that will be supported by our company in exchange.

We will be offering in exchange a competitive remuneration and an opportunity to keep evolving and growing. 

Which technologies are we working with right now?

We are mainly using React and React Native in the front-end and Redux for the state management. In the back-end we use NodeJS, C#, Python (Django, FastAPI, Pandas, Tensorflow, Numpy), C, RabbitMQ, PostgreSQL, TimescaleDB, Redis, MongoDB and others. And we hope our newcomers will bring us the chance to try new things that perform even better than the ones we are using now!
