You will guide architectural decisions, ensure performance, reliability and scalability, and work closely with product teams in a fast-paced, real-time environment.

You will mentor engineers, improve CI/CD, observability and incident response while aligning technical work with business goals. English is the working language and collaboration is key.

Qualifikationen

• Experience designing, building and operating distributed systems at scale, owning complex backend systems end-to-end in production.
• Strong backend expertise in Java (21+ preferred), with a solid understanding of JVM internals, concurrency and multithreading.
• Hands-on experience with Reactive Programming and non-blocking systems using Spring Boot and/or Vert.x.
• Hands-on experience with Apache Kafka and event-driven architectures; familiarity with Redis and other streaming/messaging technologies.
• Experience with Redis for caching and low-latency data access, and with SQL and NoSQL databases (e.g. PostgreSQL, MariaDB, MongoDB).
• Experience with observability and monitoring platforms such as Datadog, Grafana or Kibana, and with debugging complex production incidents.
• Strong system design and architectural decision-making, balancing latency, throughput, consistency and maintainability.

Aufgaben

• Lead architecture and design discussions for scalable, resilient distributed systems.
• Drive simplification while maintaining performance and code quality.
• Identify risks before production and lead root cause analysis when incidents occur.
• Improve observability, monitoring and operational readiness; reduce technical debt.
• Promote best practices around event-driven architectures, performance, testing and CI/CD.
• Mentor engineers through design reviews, code reviews, pair programming and guidance.
• Partner with Product, Engineering Managers and Architects to translate business problems into practical solutions.

Jobbeschreibung

About The Role

LeoVegas Group is building a world-class Sportsbook platform. Within the Sports domain, we work in a high-volume, real-time environment where speed, correctness, scalability and reliability are critical, building the services that transform incoming sports, trading and pricing data into experiences used by millions of customers.

We are looking for a highly experienced Staff Backend Engineer to help lead the design, development and evolution of these distributed systems. You will provide technical leadership across architecture, engineering practices and platform evolution while remaining hands-on, helping teams make better technical decisions, raise engineering standards, simplify complex systems and balance business needs with long-term platform health.

This role suits someone who enjoys understanding the technical and business context behind problems rather than implementing solutions mechanically. We value engineers who are curious and proactive, comfortable with ambiguity, and who lead through collaboration and ownership rather than authority.

What You'll Do

• Lead architecture and design discussions for scalable, resilient and maintainable distributed systems, evaluating options through spikes, experiments and proofs of concept.
• Drive simplification of complex systems while holding a high bar for performance, reliability and code quality.
• Identify scalability, resiliency and operational risks before they reach production, and lead root cause analysis when incidents occur.
• Improve observability, monitoring and operational readiness, and drive down technical debt across the platform.
• Promote best practices around event-driven and reactive architectures, performance optimisation, testing, automation and CI/CD.
• Mentor engineers through design reviews, code reviews, pair programming and technical guidance.
• Partner with Product, Engineering Managers and Architects to translate business problems into practical solutions, and help shape and break down technical initiatives.
• Contribute to a culture of ownership, collaboration, continuous improvement and engineering excellence.

Essential Skills

What We’re Looking For

• Proven experience designing, building and operating distributed systems at scale, owning complex backend systems end-to-end in production.
• Strong backend expertise in Java (preferably 21+), with a solid understanding of JVM internals, concurrency and multithreading.
• Hands-on experience with Reactive Programming and non-blocking systems using Spring Boot and/or Vert.x.
• Hands-on experience with Apache Kafka and event-driven architectures; familiarity with streaming and messaging technologies such as Redis or NATS.
• Experience with Redis for caching and low-latency data access, and with SQL and NoSQL databases (e.g. PostgreSQL, MariaDB, MongoDB).
• Experience with observability and monitoring platforms such as Datadog, Grafana or Kibana, and with debugging complex production incidents.
• Strong system design and architectural decision-making, balancing latency, throughput, consistency, operational complexity and maintainability.
• Ability to influence technical decisions and communicate effectively with engineers, architects, product managers and other stakeholders.

NICE TO HAVE

• Experience with Kubernetes, AWS and/or GCP, and cloud-native architecture patterns.
• Experience with OpenSearch and/or Elasticsearch for search, analytics and operational troubleshooting.
• Experience building internal platforms, shared frameworks or developer productivity tooling, with a strong SRE mindset.
• Experience within sports betting, gaming or other real-time, data-intensive domains.

What Success Looks Like

• Teams rely on you for technical direction and practical problem-solving, and move faster thanks to the foundations, tooling, standards and guidance you help establish.
• The platform becomes more reliable, scalable and easier to operate over time, with fewer production incidents.
• Technical decisions are made with greater clarity, consistency and long-term sustainability.
• Cross-team dependencies are better coordinated, reducing friction and improving delivery.
• Engineers grow technically through your mentorship, feedback and leadership.
