Design, implement, and maintain a low-latency real-time risk engine for perpetuals, spots, and prediction markets. Build VaR/ES and Greeks aggregation, margin and liquidation models, position limits, tail-risk models, dashboards/alerts, backtests, and circuit breakers to protect against extreme market conditions. Collaborate with trading infrastructure to meet <50ms P99 latency.

Design and implement backend trading services, own features end-to-end (schema, API, tests, UI integration), contribute to real-time infrastructure and client-facing APIs, and write integration tests against real dependencies.
