Our developers build the systems our customers use to shop for groceries — as well as the software that runs our warehouses, supports last-mile, and helps our purchasing and commerce teams operate effectively.

Crisp is de boodschappen-app waarmee je heel gemakkelijk producten in huis haalt vol smaak, volop in het seizoen, voor een goede prijs en zonder onnodige toevoegingen. Onze missie is beter eten bereikbaar te maken voor meer mensen. En daarbij kunnen we jouw hulp goed gebruiken!

What you'll do

We build software in a lean and pragmatic way, and care about choosing the right abstractions for our domain and continuously balance delivery speed against long-term complexity.

Our stack includes Typescript, React Native, modern PHP and PostgreSQL. We prefer to work with people who have seen—or want to learn—different technologies, as we consider our tools a means to an end.

You will:

  • Work with a small team of product owners and product designers to implement new app features.

  • Help validate features work as intended, from analysing technical telemetry to joining customer interviews.

  • Code across our stack — frontend and backend.

  • Ship often and take responsibility for your code “in the field”.

We invest heavily in automated testing and code readability. Refactoring is part of the job. Abstractions are revisited when the business changes.

We use LLMs as productivity tools where appropriate, but every line of code shipped to production is understood and owned by the developer who commits it.

What you bring

You likely:

  • Have several years of experience with developing for mobile.

  • Have real experience with a general-purpose language (Python, JavaScript, PHP, Go, ...).

  • Care about code quality and long-term maintainability.

  • Enjoy working directly with product designers and our customers.

  • Are comfortable taking responsibility for production systems.

Bonus points for:

  • Experience with React Native.

  • Experience chasing and solving delicate performance issues on Android or iOS.

  • Experience operating systems serving a large user base.

  • Speaking Dutch professionally (B1+).

Don’t worry if you don’t match every point above. We hire for long-term potential, curiosity and the ability to learn quickly.

What we offer

  • The chance to leave your mark on our food system and have real impact with your commitment and experience.

  • Working with the best: a high-profile team experienced in building and scaling ventures from the ground up, with diverse backgrounds.

  • The ability for you to learn quickly from others on the team.

  • A team culture based on modesty, openness and excellence.

  • Plenty of opportunity to take responsibility from day one.

  • The opportunity to shape the culture of a well established company in a new, vibrant location.

  • A competitive salary and equity/stock.

  • Regular hackweeks to work on anything you find worthwhile.

  • Time to get to know your colleagues during sports, events and tastings.
