Role Overview
You will support the senior systems architect and traders in building, optimizing, and maintaining the firm's real-time trading infrastructure. You will work on execution, quoting, risk systems, market-data handlers, and latency-critical components across multiple crypto derivatives exchanges. This role requires strong engineering fundamentals and hands-on experience with high-performance, event-driven systems
Key Responsibilities:
- Implement latency-sensitive components of the market-making engine (market-data handlers, order routers, quoting logic)
- Optimize latency, jitter, and throughput across real-time data pipelines and execution paths
- Build and maintain exchange connectors (WebSocket, REST, FIX-like variants) with robustness and micro-latency considerations
- Profile, debug, and optimize system performance in cloud-hosted environments
- Develop internal monitoring tools for latency analytics (e.g., orders, market-data delays, queue states)
- Tune garbage-collection behaviour, CPU pinning, async event loops, and other performance parameters
- Assist in creating automated stress-testing and load-testing frameworks to simulate exchange conditions
- Work closely with traders on strategy parameters, safeguards, and scenario testing
Requirements:
- 5+years of experience building low-latency applications
- Strong programming ability in Python plus at least one performant systems language: Rust or C++
- Experience building market-data handlers, quoting engines, internal order books & price caches
- Familiar with low-latency techniques (lock-free, ring buffers, cache alignment etc.)
- Hands-on experience with latency profiling and performance tuning SSTools
- Understanding of network-level latency factors
- Understanding of exchange microstructure: order types, funding, rate limit order book events, and trading halts
- Experience with Docker, containerization, and automated deployments
- Strong familiarity with Pub/Sub or stream-processing frameworks (Kafka, NAATS, Redis Streams, or custom)
- Prior experience in a crypto or traditional market-making tech stack
- Familiarity with CEX Api Quirks
