Senior C++ Engineer - Core Systems
Fionics
Job Description
A crypto-native market maker running systematic strategies across dozens of venues, on and off chain. They're hiring a senior C++ engineer to anchor and lead the core systems group in New York. This is the person the rest of engineering looks to.
Why it's worth a look
- A leadership seat on the systems a market maker lives or dies on. You set the technical standard for the core group.
- Real influence. The team is young and strong and needs a senior hand to lead it. You shape how things get built, not just keep them running.
- Heavy investment in high-performance, low-latency infrastructure. Serious engineering across dozens of markets.
- Peers out of top traditional finance firms. Research-first, well capitalised, regulated and maturing fast.
What we're looking for
- 7 to 12+ years in C++ from a tier-1 HFT or prop firm
- Deep low-latency core systems experience
- Someone who leads and mentors while still in the code every day
The bar is high. This is a seat for a top systems engineer who wants to lead.
Comp
Comp is not the constraint for the right person. They can also be patient on notice periods and non-competes.
