• Knowledge of Data Lake and Lakehouse architectures.

• Python programming skills for data processing and automation.
• Experience working in Agile environments.

What we offer:

• We are open and honest and we solve problems instead of generating them.

• A small team
• An international working environment and international projects
• Private medical care
• Sports card
• Training courses
• Work that is 100% remote (unless you prefer another system)

We have an office in Krakow, but if you like to work remotely, that’s absolutely fine. We are OK with fully remote work. For us, you can be located anywhere. :)

Why it’s a good idea to work with People More?

• If you are not satisfied with your work or your tasks, we’ll find a way out together!
• If you get bored, we will offer you a new product and new, fascinating tasks
• We will work on your brand together: you will get an opportunity to attend conferences, including as a speaker, and we will help you publish in recognized magazines and online
• We will facilitate your access to challenges that are usually difficult to get
