Server-Side Engineer (C++) - Pre-Trade Risk Technology

About the role

Millennium, a global diversified alternative investment firm, is looking for a Server-Side Engineer to join its Pre-Trade Risk Technology team. The team runs a latency-sensitive distributed system that monitors high-throughput trading flow, calculates aggregate risk metrics across hundreds of venues and blocks trades in real time to prevent control violations. The firm is updating its order management systems toward sequencer-based bus architectures with many C++ components, while its existing infrastructure is mainly Java; the role also supports building new controls, especially for Asian markets.

Key responsibilities

• Design and implement high-throughput, low-latency software to catch and prevent trading errors of millions of orders per day.
• Take ownership of your code, from implementation and test automation through deployment and operational support (level 3 only).
• Partner with business stakeholders and turn their requirements into technical solutions.
• Help build new controls, particularly for Asian markets, and integrate them with the new OMS bus architecture.

Required profile

• 5+ years of strong C++ server-side development experience on Unix/Linux.
• Experience designing and implementing front-office trading systems.
• Ability to work with business stakeholders and general market knowledge of equities, fixed income and/or other asset classes.

Required skills

• Java server-side development.
• Strong use of AI tools such as Claude Code and GitHub Copilot in the software development lifecycle.
• Experience with KDB is preferred; experience with sequencer technologies and Aeron is desired.
