Lead the technical build of the platform behind Australia’s green buildings.

At the Green Building Council of Australia, we’re rebuilding our online Green Star platforms from the ground up - and we’re looking for a Lead Full Stack Developer to help make it happen.

Green Star Online is a custom, cloud-native, multi-criteria rating application replacing a hybrid of legacy and Power Platform systems with a single modern stack. It’s a serious build: multi-source data, intricate rating logic, and real weight behind every calculation. This is a senior technical role, not a people-management one — you’ll set the standards, own the architecture, and mentor a small team while still shipping code yourself.

What makes this role different

You’ll work in an AI-led development environment, using Claude Code within GBCA’s Governed Autonomy model to accelerate design, coding,



testing and documentation - while keeping engineering standards high and staying accountable for what ships. You’ll also shape how the team uses AI well, not just how you do.

What you’ll do

- Own the architecture and technical design of Green Star Online and GBCA’s other digital products, documenting decisions on frameworks, patterns, integrations and trade-offs
- Stay hands-on across the full stack: React/Vite and TypeScript, cloud-hosted back-end services, and Azure SQL
- Define and own the platform’s security model across the application and database layers -authentication and authorisation, session and API security, least-privilege access, and encryption in transit and at rest
- Design and integrate APIs and integration layers across internal and external systems
- Design, query and optimise Azure SQL databases, and deliver reliable data migration from legacy systems with quality checks
- Own deployment through GitHub, CI/CD pipelines and a clear dev/test/prod environment strategy, with automated testing and monitoring
- Provide day-to-day technical guidance to a Full Stack Developer and a Junior Software Engineer through code review, pairing and knowledge sharing
- Set and uphold engineering standards, review the team’s code and AI-generated output, and act as the technical point of contact –unblocking issues and escalating risks
- Recommend improvements to the stack where it’s in GBCA’s best interests

The details

Full-time, 24-month fixed-term contract, with a view to becoming permanent after 12 months. You’ll report to the Senior Manager – Digital and lead a team of two.

- Degree or equivalent experience in computer science, software engineering, information systems or a related discipline
- Relevant certifications in software development, cloud platforms or database technologies (desirable)
- Minimum 5 years’ experience as a full stack developer delivering production-grade software,



including recent, hands-on delivery
- Proven experience owning solution architecture and making technology-stack and design decisions
- Experience leading or mentoring a small development team, setting engineering standards and reviewing others’ code and AI-generated outputs
- Strong front-end development with React (ideally Vite and TypeScript) and strong back-end development
- Strong SQL skills, including designing, querying and optimising relational databases (Azure SQL / T-SQL) and working across multiple data sources
- Experience with Microsoft Azure cloud services (e.g. Azure SQL, Azure Static Web Apps, App Service / Functions)
- Experience with Git/GitHub, CI/CD pipelines and modern deployment practices
- Experience building complex, logic-driven applications such as rating, scoring or calculation tools (highly desirable)
- Experience delivering data migration from legacy systems, with data-quality assurance
- Experience designing and integrating APIs and data-integration layers across systems
- Experience using AI-assisted development tools (e.g. Claude / Claude Code), or a strong aptitude and willingness to adopt AI-led workflows
- Demonstrated experience designing application and database-level security, authentication and authorisation (ideally Microsoft Entra ID / Azure AD, or equivalent), role-based access control, encryption in transit and at rest, and protection against common web vulnerabilities
- Sound understanding of software architecture, privacy, testing and deployment practices
- Awareness of accessibility standards and experience working with a design system (desirable)
- Ability to work independently, take ownership and deliver high-quality work with minimal supervision
- Strong problem-solving skills and the ability to translate complex requirements into working software
- Strong communication and collaboration skills, with the ability to lead and work effectively in a small, fast-moving team
