Sportsbook - Performance Architect

We are looking for a Performance Architect to join our Sportsbook Technology organization and take end‑to‑end ownership of performance as a first‑class architectural concern across our platform.

This role has a strong focus on frontend performance, while also requiring solid understanding of infrastructure, networking, and distributed systems, enabling close collaboration with other Architects, DevOps, and engineering teams.

The Performance Architect will work across current and future Sportsbook initiatives, ensuring that performance, scalability, and responsiveness are built in by design, not treated as an afterthought. Previous Sportsbook or high‑traffic real‑time systems experience is considered a strong advantage.

It may not be for the faint-hearted, but if you thrive on innovation, enjoy pushing boundaries and want to be part of a diverse, international team, then you’ll fit right in at Betsson.
