Job Overview

FX Client Platforms - Senior UI Software Engineer (Vice President)

About the Role

We are seeking a Senior Applications Developer to join a team delivering pricing solutions for the Foreign Exchange (FX) business. You will cover the full software development lifecycle — analysis, design, implementation, and testing — while providing technical leadership to the team.

Primary Responsibilities

Design and develop high-quality trading GUIs providing compelling user experiences for internal and external traders
Define and enforce interoperability standards across web applications using FDC3, and REST/WebSocket APIs. Experience with OpenFin or Interop is desirable but not essential.
Drive AI integration within the development lifecycle — including AI-assisted coding, automated test generation, and intelligent monitoring
Influence performance engineering across the UI stack: profiling, rendering optimisation, bundle analysis, and low-latency data delivery
Contribute and influence architecture decisions for large-scale front-end systems, including monorepo governance and design system adoption across globally distributed teams
Champion best practices in TDD, code review, and AI-assisted development tooling (e.g., GitHub Copilot)
Liaise with UI leads, UX, Product, and Sales groups to translate business requirements into robust technical solutions
Mentor junior engineers and contribute to team growth and delivery standards

Essential Experience

Solid experience building and deploying complex web application platforms in production
Expert-level proficiency in **TypeScript, React, HTML5, CSS, and JavaScript (ES6+)**
Demonstrated experience profiling and optimising high throughput React applications (Web Workers, virtual rendering, memory management)
Experience with desktop containers: **Chromium, Electron, or OpenFin**; familiarity with **FDC3** for cross-application interoperability
Experience with real-time messaging systems: **Kafka, Solace, or Tibco**
Experience with CI/CD pipelines (Jenkins or equivalent) and Agile methodologies
Strong communication skills with experience in globally distributed teams

Desirable

Experience building real-time trading platforms
FX or Fixed Income product knowledge
Java REST API development experience
Familiarity with AI-assisted development tools

This job description provides a high-level review of the types of work performed. Other job-related duties may be assigned as required.
