We’re partnering with a high-performance quantitative trading firm to hire a Front-End Engineer with deep React experience to work on the firm’s internal trading, research, and risk platforms.
This is a front-end role for engineers who care about architecture, performance, and correctness, and who want to build interfaces used by traders and quantitative researchers making real-time decisions.
The Role
You’ll own and evolve complex, data-heavy web applications that visualise live market data, research outputs, and trading activity. The emphasis is on robust engineering, not marketing websites — accuracy, latency, and usability matter.
You’ll work closely with backend engineers, quants, and traders to design interfaces that are fast, reliable, and intuitive under pressure.
Key Responsibilities
Design and build complex React applications used in live trading and research workflows
Develop reusable, well-structured component libraries and front-end architecture
Optimise rendering performance for real-time and high-frequency data visualisation
Collaborate with backend teams on APIs, data contracts, and system design
Write well-tested, maintainable code with a strong focus on correctness and usability
Core Technical Requirements
Strong professional experience with React and modern JavaScript / TypeScript
Deep understanding of front-end architecture, state management, and component design
Experience handling large, dynamic data sets in the browser
Strong grasp of performance optimisation (rendering, memoisation, data flow)
Experience working in a Linux / Git-based engineering environment
Additional Technologies (Nice to Have)
Experience with one or more of the following is a strong plus:
Next.js or similar modern React frameworks
WebSockets, streaming data, or real-time UI updates
D3.js, charting libraries, or custom data visualisation
Backend languages such as Python, C++, Java, or Go
Familiarity with GraphQL, RESTful APIs, or event-driven systems
Nice to Have (But Not Required)
Exposure to financial markets, trading systems, or time-series data
Experience working closely with quantitative or highly technical users
Knowledge of testing frameworks and front-end tooling (Jest, Playwright, etc.)
Interest in UI/UX design, without sacrificing engineering rigour
