Praha 9, CZ  Programmer Full time job Education is not essential

Knihobot is a re-commerce platform where over 5 million books have already circulated. Every day, we send around 12,000 books to new homes and gain 10,000 new customers. We aim to double these numbers within a 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 we have ambitious plans, especially for Germany. In the high season, we’re introducing the idea that a second-hand book makes a great Christmas gift. Together, we’ll create a world where second-hand has become the new European standard. To help us achieve this, we’ve recently secured €4 million in our latest investment round, and a new warehouse in Prague’s Hostivař will help expand our operations. Sound good? Check out this position and join us to conquer the European book market!

  • Cost optimization.
  • Building Next.js with static file offload to S3 + routing.
  • Optimizing the PR environment.
  • Developing Manticore autoscaling.
  • Setting up alerts and dashboards for everything—we need to know about infrastructure issues before they happen, or at least before customer support does.

  • We work from offices near Kolbenova metro station, with occasional home-office flexibility.
  • We’re straight-talking and often share a laugh, even about inappropriate jokes.

What we offer:

  • Work with awesome people like Filip (Product Manager), Simon (internal systems guru), and David (CTO). The team has a great atmosphere—we sometimes grab a beer or go rock climbing.
  • We build everything in-house, so there’s always a wide range of problems to solve and plenty of opportunities for innovation.
  • An incredible opportunity to have a significant impact on Knihobot’s success and grow along with it at an incredible pace.
  • One extra week of vacation after one year of cooperation, two extra weeks after two years.
  • MultiSport card, employee discounts for buying and selling books, parking at the office, and partner discounts.
