Our Software team is actively developing and maintaining existing mobile applications and websites, and are gearing up to an entirely new platform which will eventually encompass our existing offerings.

What you can expect from us

  1. A challenging position in a young, fast-growing and ambitious FinTech company where you can leave your suit at home (because you cannot play table football with it).

  3. Freedom to take your own initiative and responsibilities.
  4. Weekly drinks in our own bar, daily fresh fruit and the best coffee (with a cookie) you could wish for.
  5. A brand new office! Yes, we are moving to Adam Smith Building in Amsterdam Riekerpolder in November 2018 so there is more space for new colleagues. It will be a great place for work that is fresh, light, warm, transparent, connected, welcoming and flexible.
  6. The right laptop for you. Do you prefer MacOS, Windows or Linux? You choose.
  7. 26 holidays. And you can buy more holidays if you promise to come back.
  8. Money. If you are the perfect candidate, we expect that we have to pay you a salary of approx 80K EUR per annum. We also provide a mobile phone, public transport card and contribute to your pension scheme.

We don’t just want to be a bank, but a personal assistant for all your financial affairs. Knab helps people make the most of their money. Effortlessly. Quite a promise?
