Application Support Developer
About The Position
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. 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.
Requirements
- 3 to 5 years with C# and the .NET ecosystem — hands-on in both .NET Framework (including Web Forms) and modern .NET (8/9). You can navigate an unfamiliar codebase to trace a bug, not just write greenfield code.
- SQL Server — comfortable querying and patching data, and knowing when each fits.
- Experience as a systems analyst or application support role, or similar.
- You are comfortable reading code you did not write. Whether it's a stored procedure from 2014 or a service you've never seen, you can orient yourself and figure out what's happening. That's a core requirement here.
- You're patient with messy problems — you can sit with ambiguity, gather evidence methodically, and form a hypothesis before reaching for a fix.
- You take ownership of incidents end-to-end: investigation, fix, verification, and the follow-up that prevents the same issue from recurring.
- You balance "fix it now" urgency with "fix it properly" engineering instincts — and you know which mode the moment calls for.
- You mentor without being asked, and you write documentation you'd actually want to read.
Nice To Haves
- HubSpot integration experience — CRM, Custom Objects, Workflows, Webhooks, or two-way data syncs with .NET services. Broader CRM or SaaS API integration experience is equally welcome.
- Azure Data Factory, Azure Monitor, and Application Insights.
- MongoDB and T-SQL, Microservices patterns, NServiceBus, and/or Azure Service Bus for event-driven architectures, Docker, and Kubernetes
- Angular exposure — support issues occasionally pull you into the front end, but this is primarily a backend role.
Responsibilities
- 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.
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.
