Software Engineer, Backend (C#/Cloud)

Job Description

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
