Sometimes you'll work with your direct colleagues, sometimes with developers from the client, and sometimes with colleagues from our office in Bulgaria. Besides working on our vibrant campus in Amsterdam, partial remote work or working on-site at our clients' locations is also possible.

Together, you and your team will be responsible for the entire project lifecycle, working closely with each client and inspiring each other to continuously grow and improve.

  • Fluent in Dutch and proficient in English.
  • A team player with strong communication skills and a sense of responsibility.
  • Curiosity about the client's business and proactive thinking about the platform.
  • Minimum HBO working and thinking level.

What We Offer
