Lead Core C++ Engineer – Hands-on, Low-Latency Systems

Fionics in New York (on-site) seeks a Senior C++ Engineer to lead its core engineering group. You will stay hands-on while guiding architecture and performance at a crypto-native prop firm.

We value deep systems work and a track record in high-performance C++. Crypto experience is not required if you meet the technical bar, with a 12–15 month non-compete considered acceptable for the right candidate.
