Keyrock Tech Stack

Crypto market maker and asset manager building low-latency trading infrastructure

Financial Services Brussels, Brussels Region 51–200 employees Founded 2017 Privately Held

Keyrock operates a crypto trading and market-making firm built on a polyglot stack (Node.js, Python, C++, Rust, FPGA) optimized for low-latency execution and high-frequency operations. The engineering-heavy hiring profile—368 engineering roles across a 51–200-person company—coupled with active projects on system integration, settlement flows, and reliability tooling, reveals an organization scaling both trading volume and operational complexity. The shift to Rust and heavy investment in observability (Prometheus, Grafana, SIEM, EDR) signals maturation away from faster-to-market prototype code toward production-grade financial infrastructure.
