Perks of joining NN

  • We operate in a hybrid way. Most of the time you can work from home, but the team meets in the office at least once a week. NN will contribute to your HO expenses. However, during the probation period it would be better to be in the office more frequently to make onboarding easier

  • Enjoy 5 weeks of vacation, 5 well-being days, extra paid time off for personal events, and a volunteering day

  • On top of your salary, you'll get a meal allowance, up to CZK 20,000 in Cafeteria benefits, a MultiSport card option, pension contributions, and a discount on life insurance

How does our hiring process work?

There are usually two rounds. First, you'll have a chat with Veronika (Talent Acquisition Specialist) and the engineering manager - we'll tell you about the team and ask about your experience and what you're looking for. Next up is a technical talk with some of the team, just to see what you know in practice. If things go well and we're a good fit for each other, you'll have a quick call with the CDC team manager to get to know each other a bit more.
