Senior Backend .NET Engineer

THE OPPORTUNITY
  
We are looking for two Senior .NET Backend Engineers to join a well-established, cross-functional technology squad at a major ASX-listed organisation. This is a long-running program of work with a clear roadmap, a strong team culture, and a genuine October go-live milestone driving real urgency.
  
You will be embedded in an agile squad focused on building and evolving a suite of microservices and cloud-native backend systems that process high volumes of real-time transaction data. The work is meaningful, technically interesting, and directly connected to customer-facing outcomes at scale.
  
The team is tight-knit and well-led. You will collaborate closely with a technically strong engineering lead, solution architects, product owners, and other senior engineers who take quality seriously.
  
WHAT YOU WILL DO
  
  • Design, build and maintain .NET microservices on Azure, handling high-throughput data flows
  • Develop and deploy Azure Functions (HTTP, Service Bus, and Timer triggers) using the isolated worker model
  • Build and maintain data pipelines that extract, transform and load transaction data into a cloud data warehouse
  • Integrate backend services with external systems, including point-of-sale and offer orchestration platforms
  • Write clean, testable code with strong unit, integration, and API test coverage
  • Implement and maintain CI/CD pipelines using Azure DevOps
  • Contribute to production support — logging, monitoring, and alerting via Application Insights
  • Participate actively in agile ceremonies, code reviews, and squad rituals
  • Collaborate with architects and product owners to shape technical solutions from brief through to delivery
  
WHAT WE ARE LOOKING FOR
  
You are a backend-focused engineer who lives in the .NET and Azure ecosystem. Front-end work is not part of this role.
  
Essential:
  • 5+ years of commercial, modern .NET backend engineering experience
  • Strong hands-on experience with Azure — App Services, Azure Functions, Service Bus, Event Grid
  • Proven experience with Cosmos DB and/or SQL Server in production systems
  • Microservices design and delivery — ideally in a high-volume, event-driven environment
  • CI/CD with Azure DevOps — pipelines, repos, release management
  • Solid understanding of API security, SOLID principles, and clean code practices
  • Experience writing testable code and building automated test suites
  • Comfortable working in an agile squad and communicating with both technical and non-technical stakeholders
  
Highly Regarded:
  • Experience with data pipelines — Azure Data Factory, Snowflake, or similar
  • Infrastructure as Code using Bicep or Terraform
  • Azure cloud certifications (Developer Associate, DevOps Engineer Expert, or similar)
  • Background in payments, loyalty, retail technology, or consumer-facing digital platforms
  • Experience integrating with POS systems or offer/promotions engines
  
THE DETAILS
  
Rate: $950 – $1,050 per day inclusive of superannuation
Contract Length: 6 months, with the potential for extension 
Location: Sydney or Melbourne CBD
Hybrid: Onsite 1 day per week — the team values presence but offers genuine flexibility
Start: As soon as possible — there is real urgency around the October delivery milestone
