Job description

A leading multi-manager investment firm is making a significant investment in its systematic trading technology platform. The firm recently hired a highly respected senior trading technologist to lead the buildout of a next-generation research and execution platform and is now looking for several strong C++ engineers to join the team early in its growth cycle.

This is a rare opportunity to help build core trading infrastructure from the ground up rather than maintain existing systems. Engineers will have direct ownership over critical components including market data, exchange connectivity, OMS, execution, risk controls, and low-latency infrastructure while working closely with quantitative researchers, portfolio managers, and traders.

Ideal background:

• Strong C++ fundamentals and systems programming experience
• 2-5 years of experience in a professional environment
• Solid understanding of algorithms, data structures, and distributed systems
• Interest in low-latency and high-performance computing
• Linux development experience
• Desire to learn and solve complex technical problems

What makes this interesting:

• Greenfield platform buildout with significant engineering ownership
• Opportunity to shape architecture and technical direction from day one
• Direct interaction with PMs, quants, and trading teams
• Modern C++ development in a performance-critical environment
• Work on latency-sensitive trading and research infrastructure
• Join an organization continuing to invest heavily in technology and systematic trading

This position is not an internship or new graduate opportunity. Applicants must have completed their degree and have prior full-time experience.
