Full Stack Software Engineer - Remote (f/m/x)

Your mission

This is a company built for growth.

At exmox, you’ll work on real systems on a big scale. We build high-performing consumer products used by millions of users, operating in a highly competitive, global mobile gaming ecosystem.

Our products are data-driven by design - powered by event-driven architectures, complex business logic, and fast feedback loops. Decisions are informed by data, experimentation, and measurable impact, not gut feeling.

We’re scaling fast and building one of the most exciting innovations in mobile gaming: rewarded user acquisition. That means distributed systems, evolving architectures, and problems that don’t have textbook answers.

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.
