About the Role  
  
We are building a high-performance market making operation and seeking a founding member for our trading infrastructure team. As the Low Latency Market Data Engineer, you will own the full data layer, from institutional feed ingestion through to the composite real-time reference prices that power our quoting engine. This is a high-ownership, greenfield role with direct visibility into how your infrastructure drives our trading performance.  
  
Key Responsibilities  
  
\- Design, build, and maintain production-grade feed handlers for institutional market data sources and crypto exchange APIs, owning uptime, latency, and data quality SLAs.  
\- Build and continuously improve a real-time composite pricing model with dynamic source weighting, outlier detection, and automated failover logic.  
\- Profile and reduce end-to-end feed-to-application latency through kernel-level Linux tuning, CPU affinity, interrupt handling, and NIC configuration.  
\- Implement automated feed health monitoring and alerting to detect stale prices, source outages, and timestamp anomalies in real time.  
\- Collaborate closely with the trading and infrastructure teams to translate pricing model requirements into robust feed infrastructure.  
  
What We're Looking For  
  
\- 5–8 years of experience in market data engineering within a live trading environment (HFT, market making, or institutional prop trading).  
\- Hands-on production experience with institutional market data feeds such as LSEG/Refinitiv Elektron or equivalent, including feed handler development (not terminal usage).  
\- Strong Linux systems expertise, including CPU affinity, NUMA, kernel network stack tuning, and latency profiling tools.  
\- Proficiency in C++ and/or Python for production feed handler development; knowledge of OTC market data structure (FX or commodities spot pricing) is essential.  
\- Experience building composite pricing models from multiple sources; familiarity with crypto exchange WebSocket feeds is a strong plus.  
\- Fluent in English and Mandarin to effectively collaborate with Mandarin-speaking stakeholders.
