• 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
