Sportsbook - Performance Architect — Betsson Group

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.

• Partner with Solution Architects, Platform Architects, and DevOps to identify performance bottlenecks across: Infrastructure, Networking, Cloud and Kubernetes environments, APIs and backend dependencies

• Contribute to architectural decisions and roadmaps to ensure long‑term scalability and performance sustainability.

### Analysis, Measurement & Improvement

• Define and promote performance measurement standards, tooling, and dashboards.

• Lead performance analysis, load testing, and capacity planning activities together with relevant teams.
