• Collaborate with traders and quants to design, implement, and refine trading strategies and pricing systems.
• Improve system stability, scalability, and monitoring to support 24/7 global operations.
• Investigate and resolve production issues such as crashes, performance bottlenecks, and unexpected behaviors.

What you bring:

• Degree in Computer Science, Mathematics, or a related field (BSc, MSc, or PhD).
• 5+ years professional C++ experience, ideally within trading or another performance-critical domain.
• Strong knowledge of algorithms, data structures, multithreading, and asynchronous programming.
• Experience writing clean, reliable, high-performance code tuned to hardware and system constraints.
• Ability to work closely with technical and business stakeholders in a fast-moving environment.
• Candidates from any industry are welcome, as long as they have experience building high-performance C++ systems.

Why join:
