  • Develop production-quality code in Rust and/or C++
  • Optimize pipelines for performance, reliability, and scalability
  • Collaborate with quant, infra, and trading teams to ensure systems meet performance requirements

Key Qualifications:

  • Strong experience with stream processing frameworks (e.g., Flink, Kafka, NATS)
  • Hands-on experience with Rust or C++ in production environments
  • Familiarity with data lake and analytics engines like ClickHouse, RisingWave, or Arroyo
  • Understanding of real-time or low-latency system architecture
  • Bonus: Experience with Solana or other blockchain infrastructure
  • Bonus: Familiarity with Geyser plugin system or Solana RPC indexing

Preferred Qualifications:

  • Experience with Rust
  • Experience with blockchain technologies
  • Familiarity with real-time data processing
