Senior Frontend Software Engineer UI

We are looking for a Lead / Senior Frontend Software Engineer to work on Systematica’s Execution Platform, which enables large-scale systematic trading across global markets.

This role is responsible for the UI and frontend architecture of a TypeScript-based OpenFin desktop application used by traders and operations teams to oversee and control the full execution lifecycle, from model-driven order generation and pre-trade validation through smart routing, broker connectivity, and real-time execution monitoring across global markets.

You will own the design, development, and ongoing evolution of the Execution Platform UI. This includes shaping frontend architecture, building core UI features, defining patterns for state and asynchronous communication, and ensuring the application remains performant, reliable, and maintainable as the platform grows.

The role involves building a real-time, data-intensive UI where responsiveness and performance are critical. The application must efficiently process, display, and update large volumes of live trading and operational data while remaining clear, stable, and usable under demanding conditions.

You will work closely with backend engineers to specify, design, and deliver new features and projects, ensuring that UI requirements, backend contracts, real-time data flows, and operational workflows are considered together from the start.

You will lead development of the Execution Platform UI, a desktop application that provides visibility and control across trading, execution, monitoring, and operational workflows.  The frontend stack is primarily TypeScript, running in OpenFin, with real-time communication over websockets and generated API contracts from a web-gateway layer. 

The work involves close collaboration with backend engineers working on high-performance Java services, gateways, execution algos, and trading infrastructure. You will help shape how new backend capabilities are exposed through the UI, how workflows are designed for traders, and how frontend and backend contracts are defined.
