About the Role
We’re a Series B trading technology company reimagining how financial markets match buyers and sellers -- applying auction theory and innovative technologies to build fairer, more efficient trading infrastructure. Our production systems are written in Rust and execute billions of dollars in securities transactions daily. If you want to work on genuinely hard problems at the intersection of markets, mechanism design, and distributed systems, we’d love to talk.
