Tools : RabbitMQ and Kafka for messaging, PostgreSQL and Redis for data storage. Environment : Linux servers. Observability : OpenTelemetry, Prometheus, Grafana and Zabbix. Requirements Must‑Haves Strong background in software development, with strong experience with Python. A degree in Computer Science or a numerical subject from a top university.
