Application Support Developer
At Range Group we believe in the power of the professional travel advisor. We represent over $4.5 billion in annual travel sales. All our investments stem from a common thesis, that travel advisors add real value to a trip. Travel advisors when equipped with technology and 24/7 support are irreplaceable. Equally important is our philanthropy. Range Foundation channels 10% of group profits to social impact. From exploration grants, improved access to education, new discoveries on sea and land, cultural infrastructure, and helping our global neighbors in times of need — we are investing to build a better future.This is a Work-from-Home opportunity for applicants outside the commutable range of our office located at 2 Queen St. E in Toronto, ON. For local applicants, this is a hybrid position with currently 2-days a week onsite. THE ROLE We're looking for an Application Support Developer to join the TMT Technology team at TripArc. You'll split your time roughly equally between client-facing support and software development — and both halves demand strong coding ability. Understanding our application code isn't a nice-to-have; it's the prerequisite to solving most support problems. Tickets arrive in Helpspot, often partially described. You'll trace through our TMT platform's .NET code and stored procedures, figure out what the correct data state should be based on application logic, and apply a fix in code, in the database, or both. You'll also monitor lower and production environments, catching issues before clients report them. Weekend on-call is part of the rotation when production needs a fast response. WHAT YOU'LL DO Triage and resolve Helpspot tickets across our TMT Tour Operator platform — tracing through application code and stored procedures, identifying root causes, and applying targeted fixes in code or data with a rollback strategy considered before anything touches production. Monitor lower and production environments proactively, catching and resolving anomalies before they become client escalations. Build and maintain third-party integrations and data pipelines — including Azure Data Factory workflows that move data between internal databases, travel suppliers, and reporting layers. Decompose legacy .NET Framework and Web Forms code into focused .NET Core microservices, deployed via Azure Pipelines onto Kubernetes. Write and tune T-SQL: complex queries, stored procedures, and safe emergency data fixes — transaction isolation and rollback strategy first. Build event-driven integrations using NServiceBus and Azure Service Bus to keep services loosely coupled. Lead post-incident reviews that produce runbooks, code fixes, or monitoring improvements — not just incident records. Mentor junior and intermediate developers on debugging approaches and safe database practices. Collaborate with Product, QA, and Business Analysts to scope and deliver build work within two-week sprints, while staying responsive to support obligations. WHAT ...
