• Background in trading platforms, fintech, low-latency applications, or other performance-critical environments is a plus.
• Strong ownership, communication, collaboration, and problem-solving skills, with the ability to thrive in an ambiguous and rapidly evolving environment.

Responsabilidades

• Own key architecture and decisions across backend systems for scalability and reliability.
• Build and operate real-time data pipelines handling order book updates, trades, and market events.
• Design, develop, and maintain API infrastructure including GraphQL and WebSockets.
• Work with PostgreSQL, Redis, ClickHouse to support high-volume trading data.
• Optimize queries, caching, schemas, and data access patterns as data grows.
• Instrument services with metrics, monitoring, alerting; participate in on-call rotations.
