Job description

Senior C++ Engineer, Core Engineering Lead

New York (on-site)

A crypto-native prop firm hiring a senior C++ engineer to lead its core engineering group. Hands-on and technical, not a step away from the code.

Why it's worth a look

• You lead the core engineering group while staying hands-on. Real scope, real ownership.
• Team out of Tower, Goldman and Citadel Securities with a CTO from Citadel Sec.
• No regrettable turnover since inception. Good people join and stay.
• Comp is not the constraint, and they will wait out a long non-compete.

What we're looking for

• 7 to 12+ years in low-latency C++ from a top-tier firm.
• Hands-on senior engineer who can lead a core engineering group
• Deep systems and performance background
• No crypto experience required if the technical bar is met

Comp: not an issue for the right person, with tolerance for a 12 to 15 month non-compete.
