What we offer

• A highly competitive compensation package.

• Premium equipment of your choice.
• Budget for conferences, certifications, and continuous professional development.
• Enterprise AI tooling, including Claude Team/Enterprise, NotebookLM, Linear, GitHub, and modern engineering tools.
• Direct collaboration with the CTO, Architect, Product leadership, and senior engineering team.
• The opportunity to design and evolve the platform's Casino & Sportsbook integration architecture from the very beginning.
• Real ownership, fast decision-making, and long-term career growth within a modern regulated technology platform targeting multiple European markets.

Why you'll enjoy this role

This is more than another integration project.

You'll build the services that connect the platform with leading Casino and Sportsbook providers, working on high-volume transaction flows, real-money systems, and critical platform functionality.
