• Develop infrastructure for advanced capabilities, including natural language trade booking integrated with the library.
• Collaborate with quants, traders, and engineers to ensure performance and usability at every level.
• Shape systems and tooling in an environment that is still evolving—building from the ground up.
• Ensure reliability, scalability, and maintainability of mission‑critical systems.

• Influence both technical performance and human usability of large‑scale C++ systems.
• Work in a bar‑raising environment where innovation and ownership are core values.
• Direct impact on systems that drive trading decisions across global markets.

• 10+ years of experience in C++ performance engineering.
• Expertise in large‑scale codebases and environments with evolving tooling.
• Background in software infrastructure, quant libraries, or high‑performance systems.
