We are building a complex, high-load system based on a microservice architecture, where reliability and performance are critical. This is not a legacy support project - it's about continuous development of new modules, handling real-time data streams, and optimizing high-throughput architecture.

You will join our Sources team, which is responsible for integrating and processing high-volume sports data from multiple external providers — turning raw real-time feeds into reliable event streams that power the entire platform.

Our teams are small, autonomous, and focused (4-6 engineers). We operate with high ownership, build with purpose, and look for senior engineers who actively identify system or process bottlenecks, take ownership, and continuously drive technical improvements.

• Python 3.11+ (asyncio, FastAPI, Ariadne GraphQL, Pydantic v2)
• Kafka
• RabbitMQ
• MongoDB
• Docker
• Kubernetes
• Prometheus
• Grafana
• ELK
