Job Description:

Software Engineer – Distributed Market Data Systems

We are partnering with a leading hedge fund to build out a greenfield Tick Data Platform, focused on designing a globally distributed, low-latency market data system from first principles.

Role

  • Design and implement distributed, event-driven systems for real-time market data ingestion and dissemination
  • Develop horizontally scalable architectures with strong guarantees around reliability and data integrity
  • Work on in-memory processing, batching, and efficient serialization strategies to optimise performance
  • Collaborate with quant teams to deliver data abstractions and access patterns for research and execution

Profile

  • Strong academic background in Computer Science from a top-tier university, with demonstrated excellence through honours such as Dean’s List and participation in high-level competitive programming (e.g. ICPC, Codeforces)
  • Strong experience with distributed systems (e.g. partitioning, replication, consensus, fault tolerance)
  • Hands-on exposure to real-time streaming architectures (Kafka, pub/sub systems, or custom event pipelines)
  • Experience building high-throughput systems (networking, I/O, backpressure handling, load distribution)
  • Language-agnostic – all backend languages considered (Python, Java, Scala, C++, Rust, etc.), with the team currently leaning towards Python

Nice to have

  • Experience with market data protocols or tick data processing pipelines
