Full stack developer (on site)

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 across the entire stack — frontend, backend, infrastructure, testing and tooling.

• Design and implement features from idea to production.

• Improve and evolve core domain abstractions as the business grows.

• Collaborate directly with warehouse operations, commerce, service, finance and product teams.

• Take ownership of deployments and production systems — everyone ships.

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

• Understand relational databases and SQL in depth.

• Have solid fundamentals in algorithms, data structures and system design.

• Care about code quality and long-term maintainability.

• Enjoy working close to the business and solving real-world operational problems.

• Are comfortable taking responsibility for production systems.

Bonus points for:

• Experience with React or React Native.

• Experience operating systems serving a large user base.

• Strong Linux fundamentals.

• 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.
