This position is ideal for engineers who thrive on optimizing performance at the nanosecond level, are passionate about real-time systems, and are driven to push the boundaries of software and hardware performance.
Key Responsibilities
* Build and optimize latency-sensitive components of our trading stack (market data handlers, order gateways, strategy engines)
* Collaborate with traders, quants, and infrastructure engineers to design performant systems
* Profile and fine-tune code for deterministic performance under extreme loads
* Develop custom networking solutions, memory allocators, and system-level enhancements
* Maintain tight control over CPU/memory/cache performance using benchmarking and hardware introspection tools
* Implement rigorous testing, simulation, and failover mechanisms
Requirements
Essential
* Expert-level knowledge of modern C++ (C++17/20) and systems-level programming
* Deep understanding of low-latency optimization, lock-free programming, NUMA architectures, and real-time systems
* Experience with Linux internals, kernel tuning, and hardware-level optimization
* Familiarity with network protocols (TCP/UDP, multicast), kernel bypass (e.g. DPDK), or FPGA integration
* Strong command of concurrency, CPU cache optimization, and latency profiling
* 5 years minimum professional experience in the field
Preferred
* Prior experience at a high-frequency trading firm, market maker, or electronic trading platform
* Hands-on with packet capture, kernel bypass, and tick-to-trade optimization
* Experience with Python or scripting for internal tools and simulation
* Academic background in Computer Science, Engineering, Physics, or Math
Traits We Value
* Precision, performance obsession, and craftsmanship in code
* Ability to analyze and reason about hardware/software tradeoffs
* Autonomy and initiative in a fast-paced, high-stakes environment
* Effective communication in a multidisciplinary team (tech, trading, research)
Why Join Us
* Competitive comp package: base + uncapped performance bonus
* Access to cutting-edge hardware, colocated data centers, and custom research tools
* Tight-knit team of elite engineers, quants, and traders
* Opportunities to experiment, deploy, and scale your innovations in real markets
* High-impact work, with rapid feedback cycles and direct PnL visibility
