Senior Software Developer

TripArc • Toronto, ON

About The Position

We're looking for an experienced developer who thrives on autonomy and wants to make a real impact. You'll join our TMT Technology team at TripArc, where you'll navigate the interesting challenge of modernizing a mature travel platform—decomposing legacy .NET systems into Azure-native microservices while keeping the business running smoothly. This isn't a role where you'll wait for detailed specifications or step-by-step guidance. You'll own problems end-to-end: digging into complex business logic in existing codebases, designing solutions that bridge old and new, and shipping code that serves thousands of travel professionals daily. Some days you'll be untangling decade-old stored procedures; others you'll be architecting event-driven services on Azure. We need someone who finds that variety energizing rather than frustrating. You'll work within our Agile framework—two-week sprints, daily stand-ups, the usual ceremonies—but we expect you to drive your own work. That means collaborating directly with QA, Product, and stakeholders to clarify requirements, pushing back when timelines don't make sense, and helping teammates when they're stuck. Documentation matters here: we use JIRA and Confluence extensively, and your tickets and design docs should be clear enough that anyone can pick up where you left off.

Requirements

• 5+ years working with C# and the .NET ecosystem, with hands-on experience in both .NET Framework and .NET Core.
• Strong SQL Server skills—you're comfortable writing complex queries, optimizing performance, and working with large, intricate database schemas.
• Experience building and consuming RESTful APIs and working with Entity Framework or similar ORMs.

Nice To Haves

• MongoDB experience
• Familiarity with message-based architectures; NServiceBus or Azure Service Bus experience is preferred.
• Exposure to CI/CD pipelines, ideally Azure Pipelines or similar tools.
• Working knowledge of containerization (Docker) and orchestration (Kubernetes) in a cloud environment.
• Angular experience is a plus if you're interested in occasional front-end work, but this is primarily a backend-focused role.

Responsibilities

• Design, build, and deploy features across our stack—from legacy Web Forms applications to modern .NET Core microservices running on Kubernetes.
• Lead migration efforts, breaking down monolithic components into loosely-coupled services while maintaining system reliability.
• Write and optimize complex SQL queries and stored procedures; work with MongoDB for document storage where appropriate.
• Build and maintain event-driven integrations using NServiceBus and Azure Service Bus.
• Collaborate with Product and QA to scope work, estimate effort, and balance competing priorities within sprint commitments.
• Own your deliverables through the full lifecycle: design, implementation, testing, deployment via Azure Pipelines, and production support.
• Contribute to architectural decisions and help establish patterns that the broader team can follow.
• Support fellow developers through code reviews, pair programming, and knowledge sharing—elevating the whole team's capabilities.
• Maintain clear documentation in Confluence and keep JIRA tickets updated so the team has visibility into progress and blockers.

Benefits

• Competitive compensation package with a strong pay-for-performance rewards approach.
• Opportunity to participate in incentive programs and compensation tied to business and individual performance.
• Employment accommodation in accordance with the Ontario Human Rights Code and the Accessibility for Ontarians with Disabilities Act.
