- Bureau à Spain
We are on a mission to pioneer the world’s next era of play. As we grow across Europe and Latin America, we’re building The Playstack - the technology powering the next generation of sports, gaming, and fan experiences. Join us, and help make it the most widely used platform in the world! From operations, to marketing, to product, we are looking for talented people who will shape how millions of customers play, watch, and connect every day.
Super is building the future of entertainment across Europe and Brazil. Within the Core Experience area, the Explore tribe drives the experiences that help players find what they love — from the homepage and navigation to search and discovery systems. As a Senior or Staff Backend Engineer, you will design and scale a unified search platform that powers discovery across all of Super's product verticals, working at the intersection of backend systems, data pipelines, and relevance engineering.
What the role involves
- Design and implement distributed backend services that power real-time search and discovery across multiple product verticals.
- Build and optimise indexing, retrieval, and ranking pipelines (e.g., combining BM25 keyword retrieval with vector embeddings and personalisation signals).
- Partner with ML, Infrastructure, and Product teams to evolve search relevance, ranking, and experimentation frameworks.
- Architect and evolve API contracts to support multiple clients (web, mobile, internal tools) with low-latency, high-availability performance.
- Drive technical direction for Search — influencing architecture, observability, scalability, and cost efficiency.
- Contribute to a shared Search platform that other verticals (Sports, Casino, etc.) can extend and build upon.
- Mentor engineers across the Explore tribe, raising the bar for backend design and operational excellence.
What we are looking for
- 6+ years of backend engineering experience, preferably in distributed systems, data platforms, or search domains.
- Deep knowledge of one or more backend languages (Python, Kotlin, Java, Go, Elixir) and proficiency in API design and microservice architecture.
- Experience with search technologies such as OpenSearch, Elasticsearch, Lucene, or vector databases (e.g. Pinecone or FAISS).
- Familiarity with indexing pipelines, ranking models, embeddings, or relevance tuning.
- Hands-on experience with streaming and data processing frameworks (Kafka, Spark, Flink, Airflow, or similar).
- Solid understanding of scalability, caching, and performance optimisation in high-traffic systems.
- Experience integrating backend services into CI/CD pipelines and monitoring via Datadog, Grafana, or similar tools.
- Strong communication and collaboration skills, with the ability to work effectively in cross-functional teams.
- Bachelor's or Master's degree in Computer Science or a related field.
Nice to have
- Experience designing or operating multi-tenant or cross-domain platforms.
- Background in search relevance, feature stores, or personalisation pipelines.
- Exposure to experimentation and A/B testing frameworks.
- Comfort with infrastructure-as-code (Terraform, AWS CDK) and container orchestration (Kubernetes).
What we offer
- Medical / Health Insurance
- Open Annual Leave
- Employee Assistance Programme
- Training & Learning Development
Additional benefits vary by country and will be shared during the hiring process.
