Full Job Description

Overview

Work Type: Fixed-term - Full-time

Salary: $116,413 - $140,849

Grade: VPS 5

Occupation: IT and telecommunications

Location: Melbourne - CBD and Inner Metro suburbs

Reference: 2055

The Residential Energy Rating team is looking for software developers and specialists to join our growing team.

The Opportunity

We are looking to fill a Full Stack .NET Developer role contributing to the development and enhancement of the FirstRate5 (FR5) web portal and related cloud applications. FR5 is one of Australia's accredited tools under the Nationwide House Energy Rating Scheme (NatHERS), used by Thermal Performance Assessors (TPAs) to simulate and compare residential heating and cooling energy demands, producing certificates for National Construction Code (NCC) compliance.

The FR5 Web Portal is built on .NET Framework 4.8 using ASP.NET MVC / Web API and integrates with Sitefinity CMS. Over time, we are modernising and refactoring the solution to reduce dependencies on Sitefinity, moving toward a clean, domain-driven architecture where the application can run independently if required.

The role involves delivering new features while also contributing to ongoing refactoring and architectural separation efforts. You'll work with MVC (Model-View-Controller) controllers, APIs, and Vue.js components to deliver modern, maintainable solutions.

You'll also contribute to .NET 8 Azure Functions apps in the FR5 ecosystem. While the role is primarily focused on the FR5 .NET web applications, it will also provide primary development support for the Whole of Home (WoH) Node.js application when required, focusing on stabilisation, defect resolution, and incremental improvements while supporting the transition away from the application.

This position is ideal for a motivated developer with a strong grounding in C#, MVC, and web development best practices who is eager to grow their skills in Clean Architecture, Domain-Driven Design (DDD), and frontend development while contributing to a nationally significant software product that impacts energy efficiency across Australia.

This role is delivery-focused across modern web technologies, contributing to platform evolution within established architecture and under senior technical direction.

Duties

1. Software Development & Architecture

Develop and maintain the FR5 Web Portal using ASP.NET MVC (Sitefinity CMS), C#, and related technologies.

Implement modern, reusable Vue.js components to deliver complex, interactive UIs.

Contribute to RESTful Web APIs consumed by internal and external applications.

Support development of small .NET 8 Azure Function Apps used in the FR5 ecosystem.

Provide primary development support for the Whole of Home (WoH) Node.js application when required, focusing on stabilisation, defect resolution, and incremental improvements.

Support transition activities to reduce reliance on WoH over time (e.g., incremental migration, decommissioning planning, or replacement solutions), in line with agreed priorities.

Write clean, testable, and maintainable code aligned with DDD and Clean Architecture principles.
Participate in code reviews and collaborate on design decisions.

2. Collaboration & Growth

Work collaboratively with senior developers and the Technical Lead, contributing to team delivery goals and taking ownership of assigned features and refactoring tasks.

Collaborate with cross-functional teams including user experience (UX), product, quality assurance (QA), and business stakeholders.

Demonstrate willingness to learn and expand skill sets, particularly in Sitefinity, Vue.js, and Azure Functions.
Share knowledge with peers and contribute to a culture of continuous improvement.

3. Quality & Process Improvement

Apply best practices in version control (Git), continuous integration/continuous delivery (CI/CD), and testing.

Contribute to maintaining high standards of code quality, documentation, and architectural consistency.

Participate in Agile ceremonies and iterative development cycles.
Support improvements in development workflows and tooling.

Skills and relevant experience

1. Technical Expertise

Demonstrated commercial experience delivering and maintaining C#/.NET web applications in production environments.

Experience with ASP.NET MVC (experience with Sitefinity CMS highly regarded).

Familiarity with JavaScript frameworks (Vue.js preferred; React or Angular also considered).

Understanding of Web APIs, REST, and integration patterns.

Exposure to Azure DevOps, Azure Functions, and Azure cloud services.
Experience maintaining a Node.js application in production, or demonstrated ability to quickly learn and support an existing Node.js codebase.

2. Software Engineering Best Practices

Strong grasp of object-oriented programming and design patterns.

Demonstrated experience refactoring legacy applications to improve maintainability, reduce coupling, and align with modern architectural principles.

Commitment to clean code, testability, and maintainable architecture.

Familiarity with DDD and Clean Architecture principles desirable.

3. Collaboration & Communication

Ability to work effectively in a collaborative Agile team environment.

Good written and verbal communication skills, able to translate requirements into working solutions.

4. DevOps & Tooling

Proficiency with Git and experience in CI/CD pipelines (Azure DevOps or GitHub Actions).
Experience with Agile development processes.
