Senior Frontend Developer

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.

What You’ll Work On

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.

Key Responsibilities

• Own the design, architecture, and delivery of the Execution Platform UI.
• Lead frontend development for trading, execution, monitoring, and operational workflows.
• Develop high-quality TypeScript code for a desktop application running on OpenFin.
• Design and build responsive, performant UI components capable of handling large volumes of real-time trading and operational data.
• Work closely with backend teams to specify, design, and deliver new features, services, workflows, and platform projects.
• Translate trading and operational requirements into clear UI behaviour, data requirements, and frontend/backend integration contracts.
• Work with real-time event streams, connection state, subscriptions, asynchronous workflows, and changing backend availability.
• Apply appropriate techniques for efficient data processing, rendering, state updates, memory usage, and latency-sensitive user interaction.
• Define and maintain frontend patterns for state management, asynchronous communication, service integration, and component design.
• Improve usability, resilience, latency perception, and clarity across operator-facing workflows.
• Collaborate closely with backend engineers across Java services and distributed systems.
• Provide technical leadership for frontend decisions while staying aligned with the wider platform architecture.

Skills, Knowledge and Expertise

• Strong commercial experience with TypeScript or modern JavaScript frontend development.
• Experience as a senior frontend engineer, UI engineer, or frontend technical lead on complex software systems.
• Experience owning frontend architecture, UI design patterns, or major areas of a production application.
• Experience building complex, data-intensive UIs for real-time, operational, or high-throughput systems.

Preferred Experience

• Experience with OpenFin or similar desktop container technologies.
• Experience in financial systems, trading platforms, market data, OMS / EMS, execution systems, or low-latency operational tooling.
• Experience collaborating with Java backend teams in distributed systems environments.
• Experience building tools used by traders, operations teams, support teams, or other high-pressure technical users.
• Experience leading frontend technical direction in a small, high-impact engineering team.

Educational & Professional Qualifications

• Educated to degree (or equivalent) level or higher.
