Senior Trading Systems Engineer
We’re hiring a Senior Trading Systems Engineer. You’ll harden our exchange connectors (WebSocket / REST / FIX / Binary), reduce tail latency, troubleshoot production issues, and work closely with traders and quants to keep our market-making and latency-arbitrage systems reliable and competitive.
You will dissect and optimize complex trading systems in low-latency crypto environments — analyzing live behavior, identifying performance bottlenecks, and challenging design choices across algorithms, exchange connectors, and platform components.
Key Responsibilities
Conduct deep-dive investigations into trading behavior and system performance.
Optimize exchange connectors (WebSocket / REST / FIX / Binary) for reliability and latency.
Reduce tail latency and improve determinism across trading pipelines.
Investigate production incidents and perform thorough root-cause analysis.
Identify and resolve issues in algorithmic logic, execution flow, and connector behavior.
Analyze order books, packet captures, and latency distributions to improve trading outcomes.
Review and challenge platform architecture and low-latency design decisions.
Collaborate with traders, developers, and infrastructure engineers to maintain optimal trading performance.
Contribute to postmortems, debugging frameworks, and continuous improvements in trading strategies and infrastructure.
Qualifications
- 5+ years of experience in trading systems, exchange technology, or low-latency infrastructure (crypto experience preferred).
Hands-on experience with market making and/or latency arbitrage.
Deep understanding of order books, matching engines, snapshots and incremental market data feeds, sequence-recovery mechanisms, and feed-arbitrage practices.
Experience working with exchange connectors, pcap/tcpdump analysis, and production postmortems.
Proficiency in Python for tooling, debugging, and performance analysis.
Will be a plusLow-latency engineering experience in C++, Rust, C#, or Java.
Strong Linux and networking fundamentals (kernel behavior, TCP, packet flow, performance tuning).
