About the Role

We are seeking an exceptional C++ Software Engineer to design and implement high-performance systems that underpin our trading infrastructure. In this role, you will be responsible for building and optimizing real-time systems that handle market data, order execution, and strategy deployment with minimal latency and maximum reliability.
This is a hands-on engineering role with end-to-end ownership of critical components in a live trading environment. The ideal candidate has deep expertise in modern C++ and a strong understanding of system-level performance.

Requirements

Minimum Qualifications

3+ years of professional software engineering experience, with a focus on performance-critical systems.
Expert-level proficiency in modern C++ (C++17 or newer), including templates, memory management, and concurrency.
Strong understanding of systems programming concepts (CPU architecture, networking, threading, I/O, etc.).
Experience with Linux systems development, including debugging and performance tuning tools.
Demonstrated ability to write clean, efficient, and maintainable code in production environments.
Strong problem-solving skills and attention to detail.
Comfortable working independently in a fast-paced, fully remote team environment.

Preferred Qualifications

Prior experience in high-frequency trading, low-latency systems, or real-time financial infrastructure.
Experience implementing market data handlers, matching engines, or order gateways.
Familiarity with exchange protocols (FIX, WebSocket, REST) and crypto-native APIs.
Background in mathematics, physics, computer science, or a related technical field.
Experience with performance benchmarking and micro-optimization at the hardware level (e.g., cache-aware design, CPU pinning, instruction pipelining).
