Senior Full-Stack Developer / React Front-End Expert

At Nöord Technologies, we empower top-tier financial institutions with exceptional talent in banking and capital markets. For the needs of one of our prestigious clients, a major banking actor in Montreal currently experiencing strong growth, we are actively seeking an experienced Senior Full-Stack Developer / React Front-End Lead (with strong C# Backend expertise).

About the Role

As part of an elite Capital Markets technology team, you will take ownership of mission-critical, data-intensive systems used in real time by global trading desks to track risk exposure and manage interest rate curves.

This role is heavily focused on the front end (approximately 70% Front-End / 30% Back-End). We are looking for a true React and TypeScript expert capable of designing complex, highly responsive, and high-performance user interfaces. In parallel, you must possess solid, hands-on experience in C# .NET Core backend development to actively support backend teammates and ensure seamless end-to-end integration across services.

Key Responsibilities

Design, architect, and develop responsive, high-performance UI components using TypeScript and React for real-time trading applications.

Actively collaborate on server-side microservices and APIs in C# .NET Core alongside the dedicated backend engineering team.

Optimize render performance, state management, and real-time streaming data pipelines using SignalR, WebSockets, and Redux.

Provide Tier-3 technical support and assistance to North American trading desks during active afternoon market sessions.

Maintain and enhance continuous integration and deployment pipelines (CI/CD).

Champion software craftsmanship standards: clean architecture, SOLID principles, comprehensive unit testing, and BDD practices.

Coordinate and communicate effectively across international, multi-disciplinary delivery teams in North America, Europe, and Asia.

Domain Expertise: Prior background in Capital Markets, Corporate & Investment Banking, or front-office trading systems (Rates, Pricing, Risk) is strongly preferred.

Language Skills: Fluent English is mandatory for global team collaboration; French is a valuable asset / nice to have
