• Collaborate with Product, QA, Architecture, and trading desks
• Provide tier-three backend support during North American market hours
• Improve CI/CD, telemetry, and distributed messaging infrastructures

Requirements:

• Eight-plus years of dedicated C# .NET Core backend experience
• Expertise in concurrency, multithreading, memory management, and microservices
• Production experience with Kafka, Kubernetes, AWS, ELK, APIs, and Git
• Knowledge of SOLID, clean architecture, testing, and BDD
• Fluent English and Canadian work authorization required

Apply your backend engineering expertise to low-latency financial systems, real-time risk computation, and distributed services in Montreal.
