# Principal Engineer

Our trading platform is the engine the fund runs on. We're looking for the engineer who will own it — the architecture, the code, and the team that builds it. You will set the technical direction and make the hard architectural calls, and you will stay deep in the code, building the most critical and latency-sensitive parts yourself. You will lead a strong engineering team, and you will be accountable for everything the platform does in live markets: that it's fast from tick to trade, that it's correct, that it stays up while markets are open, and that it behaves safely with real capital. This is a builder's leadership role. You own the outcomes across the whole platform — including its connectivity, colocation, resilience, security, and regulatory posture — and you will shape the infrastructure and the exchange, broker, and vendor relationships beneath it. What this is not is an IT-administration job: as we grow, dedicated infrastructure and operations support will carry the hands-on run-work so you stay focused on building and leading. Responsibilities: The architecture and technical direction of the platform end to end — market data, signal, execution, and risk — and the call
