Mô tả công việc

Titan DMS is a comprehensive Dealer Management System (DMS) serving automotive dealerships across Australia, the Middle East, UK, Japan and Asia-Pacific. Built on a mature .NET technology stack, the product handles end-to-end dealership operations — vehicle sales, service workshops, parts inventory, accounting, and third-party OEM integrations.

Our Professional Services team delivers manufacturer integrations, API Gateway services, custom reporting, and emerging core features. We're looking for a Mid-Level .NET Developer to join us and contribute across the full breadth of our delivery.

Stack you will work with: 

Core

• C# / .NET Framework

API & Services

• ASP.NET Core Web API
• RESTful Services
• API Gateway patterns (routing, authentication, rate limiting)

Database

• Microsoft SQL Server
• T-SQL Stored Procedures

Integrations

• OEM Manufacturer APIs (Ford, BMW, Toyota, etc.)

Desktop

• Windows Forms (maintenance & modernisation)

DevOps

• Git
• Azure DevOps
• CI/CD Pipelines

What You'll Do

• Build and maintain the desktop application — build and maintain WinForms screens and incrementally refactor toward modern patterns.
• Develop manufacturer and third-party integrations — map payloads and handle real-time and batch data exchange with OEM systems (Ford, BMW, Toyota, Jaguar/Land Rover, etc.).
• Write and optimise T-SQL stored procedures for data retrieval, reporting, and integration logging.
• Build and maintain RESTful APIs and integration services — design endpoints, implement authentication (OAuth2/JWT), versioning, and request/response transformation.
• Implement observability — API logging, monitoring dashboards, and error tracing for integration health.
• Participate in code reviews, technical design discussions, estimation, and team workshops.
• Collaborate using Jira for task tracking and Confluence for documentation.
