Задачи

• Architecture and technology selection: assess and choose the most suitable Big Data / NoSQL engine for high-frequency market data and trade execution logs.
• Infrastructure ownership: take responsibility for installation, configuration, scaling and long-term operation of the database environment.
• Design: define the schema and storage strategy for very large datasets, ensuring high availability and resilience.
• Query and performance tuning: write and optimize complex time-series queries (execution quality and liquidity metrics) so that real-time monitoring tools respond in under a second.
• Knowledge sharing: act as the subject matter expert and coach front-end developers and teammates on efficient ways to query and use the data layer.
• Collaboration: work closely with the team lead and UI developers so the data infrastructure fully supports product needs.

• Deep expertise in at least one leading Big Data or time-series database (for example ClickHouse, InfluxDB, or ScyllaDB/Cassandra)
• Proven experience operating high-velocity data environments (streaming ticks, execution logs, order book events)
• Strong skills in writing and tuning complex queries over very large datasets (billions of rows)
• Extensive experience in Linux-centric environments, with a focus on system-level performance and low-latency tuning
• Ability to turn business metrics into efficient data structures, without necessarily writing application-level code
• Excellent English communication skills
• Experience in financial markets or trading technology (e.g. FIX protocol)
• Background in high-performance hardware/software integration
• Automation scripting (Python, Bash)
