Software Engineer, Backend (C#/Cloud)
We are seeking a backend-focused C# engineer who wants meaningful ownership of real production systems. In this role, you will design, build, deploy, and operate core backend services end-to-end, contributing directly to product capabilities while helping shape how our cloud infrastructure, deployment workflows, and operational reliability evolve.
This is a backend-first position—not a pure DevOps role—but we expect comfort working across application code, cloud environments, and production operations to ensure the systems you build run reliably with minimal support.
Job Responsibilities
- Design, build, and maintain backend services in C#
- Own features end-to-end from technical design through deployment and production operation
- Develop and support integrations with external partners, utilities, and market systems
- Improve system reliability, observability, scalability, and performance
- Containerize and deploy services within cloud environments
- Work directly with CI/CD pipelines, monitoring, logging, and runtime configuration
- Contribute to Kubernetes adoption and cloud architecture evolution
- Diagnose and resolve production issues across application, infrastructure, and data layers
- Collaborate with cross-functional engineering and product teams to deliver customer value
Requirements
- Candidates must be legally authorized to work in Canada at the time of application
- 3+ years of professional experience building backend software systems in C#
- Experience deploying and operating production services
- Ability to debug and resolve issues across:
- Application code
- Infrastructure/runtime environments
- Databases or data flows
- Comfort taking a service from local development to reliable production operation with minimal hand-holding
- Strong problem-solving skills and ability to work effectively in high-ownership, evolving environments
Nice-to-Have Experience
- Familiarity with containers, Kubernetes, or Azure cloud environments, including CI/CD workflows such as Azure DevOps
- Strong grounding in relational data modeling and access patterns (e.g., PostgreSQL, ORMs like Entity Framework)
- Comfort with observability, incident response, distributed or event-driven systems, or data pipeline architectures
- Background in smaller teams or growth-stage environments with high ownership and autonomy
