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.
The mission Today, our search experience is fragmented – each vertical (Sports, Casino, Superscore, Supersocial) maintains its own implementation, leading to inconsistent behavior, higher maintenance costs, and missed opportunities for discovery and conversion.
You’ll work at the intersection of backend systems, data pipelines, and relevance engineering — shaping how users find and explore content across products, platforms, and geographies.
Design and implement distributed backend services that power real‑time search and discovery across multiple product verticals.
Architect and evolve API contracts to support multiple clients (web, mobile, internal tools) with low-latency, high-availability performance.




Contribute to a shared Search platform that other verticals (Sports, Casino, etc.) Mentor engineers across the Explore tribe, raising the bar for backend design and operational excellence.
You’ll have significant technical ownership and leadership visibility, collaborating directly with senior engineers, data scientists, and product leaders.
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 (OpenSearch, Elasticsearch, Lucene, or vector databases such as Pinecone or FAISS).
~ Hands‑on experience with streaming and data processing frameworks (Kafka, Spark, Flink, Airflow, etc.).
~ Solid understanding of scalability, caching, and performance optimi
