Knihobot & Bookbot is the largest re-commerce bookstore in the Czech Republic. Every day, we return pre-read books back into circulation, helping to protect the environment. So far, we've processed over 5 million books. Currently, we operate in four markets (DE, AT, CZ, SK), with ambitious growth plans, especially in Germany. Our success is directly tied to our expertise in data.
We have over a million books in our warehouse, and every day we receive another 20,000 while sending out about the same amount. This is why we need to leverage data fully. We aim to get books—with all the right information and prices—onto our e-shop as quickly as possible, ensuring they reach the right customers efficiently.
We work at a fast pace, with minimal bureaucracy. Sustainability and positive environmental impact are core to what we do. You'll see the results of your work daily and play a crucial role in driving the company's growth.
What to expect:
- You’ll be part of an internal data team of 5–8 people, working closely with IT, BizDev, Marketing, and Product teams. You’ll collaborate with key people like Markéta (Head of Data), Mikuláš (Product Owner, Books), and Patrik (AI Engineer).
- Delivering data products for projects across the entire Knihobot world.
- Developing in the cloud, building data warehouses and pipelines capable of handling tens of millions of records daily.
- Your main focus will be on web analytics and marketing data. Pinpointing where marketing spend has the greatest impact. Analyzing customer journeys through our websites. Identifying which product changes drive results, and which do not.
Example projects you’ll work on:
- Analyzing no-result searches on our website to identify potential content gaps and high-demand terms that should be supported.
- Fine-tuning our marketing attribution models to determine which channels drive the most impact.
- Optimalization of product feeds to marketing platforms.

- Familiarity with data development best practices: version control (GitHub), testing, automated QA.
- AWS experience is a plus.
- Experience working with big data is a plus.
- You are independent, proactive, and take ownership of your tasks, but also enjoy working in a team.
