Original job description

React Developer, Electronic Trading Platform | 6-Month Contract | Hybrid Toronto

My client, one of Canada’s Big 5 banks, is hiring a React Developer for its electronic trading technology team. The team builds the platform institutional clients use to manage orders, control algorithmic trading strategies, and analyze execution in real time. Performance is central to the work: you’ll be building interfaces for streaming market data, live order flow, and dense grids that update constantly.

This is a hands-on role. It suits someone who writes excellent code and also thinks about how the whole application should be built.

What you’ll do

Build and maintain front-end applications using React, Redux (or similar), and modern JavaScript (ES6+)
Build UIs that display real-time market data, order flow, and trading analytics without lag
Work closely with product owners and UX/UI designers to turn complex trading workflows into clear, usable interfaces
Integrate with backend services and APIs, including real-time data feeds
Write clean, well-tested, maintainable code, and troubleshoot production issues
Contribute to front-end architecture decisions and mentor other developers

What you bring

5–8+ years of front-end development experience, with deep expertise in React
Strong JavaScript (ES6+), HTML5, and CSS3
Experience with modern state management (Redux, MobX, Zustand, or similar)
Solid understanding of RESTful APIs and asynchronous data handling
A track record of building fast, high-performance UIs and solving rendering bottlenecks
Proficiency with Git
Bachelor’s degree in Computer Science, Engineering, or a related field

Strongly preferred

Experience with AG Grid
Experience with OpenFin
Background in banking, capital markets, or trading platforms, especially building an order management system (OMS) in any asset class
Financial data visualization experience

The details

6-month full-time contract
Hybrid: 2 days per week onsite in Toronto
Pay: $90–$120/hr depending on experience and engagement type (up to $100/hr T4 or up to $120/hr Inc.)
This posting is for an existing vacancy

If you’ve built trading UIs, or the kind of real-time, data-heavy interfaces that translate well to one, I’d like to hear from you.
