A proprietary and algorithmic trading firm - New York - forty years in the market and still investing heavily in engineering - is looking for a C++ Software Engineer to join their core low-latency market data team in New York. This is a hands-on individual contributor role working directly on the trading engine: exchange connectivity, market data processing, and algorithmic execution.

The firm is one of the recognised names in global electronic trading, with a long track record of building and owning their technology rather than buying it. Several high-profile internal projects are beginning in Q4 2026 and this hire will be part of them from the start.

This is pure engineering - no people management, no line reports. The expectation is deep technical contribution on systems where microseconds matter and correctness is non-negotiable.
