Fullstack developer - Medior

Knihobot is a re-commerce platform where over 5 million books have already changed hands. Every day, we send around 12,000 books to new homes and gain 10,000 new customers — figures we plan to double within the next year. We're among the top 10 fastest-growing tech startups in the CEE region and have won the Heureka ShopRoku award for 2021, 2022, and 2023.

We operate in four European markets (CZ, SK, AT, and DE) and have big plans, especially in Germany. In our high season, we spread the idea that a second-hand book makes a great holiday gift—and together, we aim to make second-hand the new European standard. A new warehouse in Prague's Hostivař and €4 million from our latest funding round will help us on this journey. Sounds exciting? Take a look at the position and join us in conquering the European book market!

• We dedicate time to technical debt and code clean-up.
• Our team currently consists of 14 members (13 developers + CTO).

What we offer:

• Collaborate with awesome people like Product Manager Filip, Designer Štěpán, internal systems guru Simon, and CTO David. The team is full of good vibes, and sometimes we go for a beer or rock climbing.
• Listen to a podcast with David (CTO) & Simon to get an even better understanding of how our development team works and what we’re currently tackling.
• We build our entire system in-house, meaning there’s a wide variety of problems to solve and endless opportunities to learn and create.
• You’ll see the results of your work immediately—when we rework or optimize a process, it typically has visible positive effects, not just on the website but also in the warehouse, shipping, customer support, or intake. If something goes wrong, you'll hear about it within minutes!
• Everything we create is tailored in-house.
• An amazing opportunity to have a significant impact on the future of Knihobot, and to grow with us exponentially.
• Multisport card, employee discounts on buying and selling books, plus partner discounts.
