We offer a strong engineering culture and are looking for engineers to design and optimize high-performance trading systems that power our periodic auction matching infrastructure. We build production systems in Rust and are seeking engineers with meaningful Rust, C++, Java, or Python experience, particularly from backend or systems-oriented environments. Systems Engineer: Systems programming role focused on low-latency, high-throughput distributed computing. Work across order and data workflows, auction execution, reliability, and performance optimization to ensure the platform is efficient, fault-tolerant, and capable of complex trade matching at scale. We're especially interested in engineers who have built backend or systems-level software, care deeply about performance, concurrency, and correctness, are motivated by real-time, performance-sensitive systems, and have experience with compilers, static analysis, or language tooling (a strong plus). Software Engineer, Data Platform: Build and evolve the infrastructure behind our analytics platform. The role sits between data engineering and backend development and focuses on high-volume, time-sensitive data pipelines and workflow systems that process terabytes of trading data and billions of rows daily. We're especially interested in engineers who have built internal data platforms or large-scale pipelines (Python/SQL; Rust a plus), have experience with workflow orchestration (Temporal, Airflow, Dagster, etc.), and have worked with large datasets, columnar formats (Parquet/Arrow), and production data systems.
