Requirements:- Experience building and running production services in Python, including performance optimization;

- Understanding of ML and A/B testing well enough to work on equal terms with DS;
- Ability to understand business context, gather requirements and own technical decisions;
- Experience with high-load or low-latency systems, ad tech, or mobile games is a plus;
- B2+ level of English;
- Fluent Russian is required. Benefits: Besides the engaging tasks, support from experienced colleagues, challenge, and drive, we offer:
- Full support in relocating to countries where our offices are located;
- High-end market salary with performance bonuses;
