Senior Fullstack Engineer

As Senior Full Stack Engineer (m/f/x) you won't just be "coding tickets" or maintaining legacy systems. We look for people with an engineering mindset and entrepreneurial ownership - you build it, you own it. You'll work close to product and data, take responsibility for what you ship, and see the impact of your work in production.

If you're excited by complex systems, high traffic, data-driven decisions, and the chance to grow by solving challenging problems, we want to hear from you.
