Solid understanding of microservices architectures, including:
- Service boundaries and ownership
- Inter‑service communication patterns
- API design, versioning, and governance
- Scalability, resiliency, and fault‑tolerance concepts
Proven hands‑on experience with Docker and containerized applications
Experience designing and consuming REST APIs
Comfortable working in Linux environments
Proficiency with Git and collaborative development workflows
Good understanding of concurrency, networking, and performance considerations in backend systems

Observability & Operations

Experience with logging, monitoring, and alerting in production environments
Familiarity with observability concepts and tools (metrics, distributed tracing, logs)
Ability to diagnose and analyze issues across multiple services, containers, and infrastructure layers

Assets / Nice to Have

Experience working with embedded systems or systems close to hardware
Knowledge of the C# language, particularly in system‑level tools, utilities, or backend integrations
Background in telecommunications, network monitoring, or fiber‑optic networks
Familiarity with event‑driven architectures and real‑time or near‑real‑time distributed systems
Experience with iOS and/or Android mobile development, particularly for visualization, diagnostics, or control applications, is considered an asset
Understanding or practical experience with AI coding assistants and agent‑based development tools (e.g., Cursor or similar)

Soft Skills & Mindset

Naturally curious and motivated to deeply understand how systems behave in production
Self‑driven and autonomous, able to own features from design through deployment
Strong analytical and problem‑solving skills
Clear communicator, comfortable collaborating across teams
High standards for quality and a strong sense of ownership for production systems
Team‑oriented with a proactive attitude

Requirements

Bachelor’s degree in Software Engineering, Computer Science, or equivalent professional experience
Working or fluent English required (French is a strong asset)
Legal authorization to work in Canada

What We Offer

Competitive salary and comprehensive benefits package
Hybrid and flexible work environment
Opportunity to work on real‑world infrastructure at global scale

Participer aux décisions d’architecture, aux revues de conception et aux revues de code
Diagnostiquer et résoudre des problèmes complexes dans des systèmes distribués en production
Contribuer aux pipelines CI/CD, aux tests automatisés et aux bonnes pratiques d’ingénierie
