Old Mission operates a trading infrastructure stack spanning Python, C++, PostgreSQL, and Kubernetes — built for low-latency execution across equities, options, and FX. The tech mix (Protocol Buffers, WebSockets, Docker orchestration) reflects a systems-first approach to pricing and risk. Active hiring across engineering, quantitative research, and finance (in near-equal measure) suggests simultaneous scaling of execution capability, model sophistication, and operational depth; adoption of Bazel signals investment in build-system maturity as engineering scope grows.
