LAB3 is one of Australasia's largest Azure engineering practices, specialising in Cloud & DevOps, Data, IoT & AI, Modern Workplace, Security, and Networks. We're looking for a Senior Full Stack Developer to join our Technology Team, building the internal platforms that help LAB3 run and delivering AI-powered applications for our clients.

The role:

• Own software end to end, taking features from architecture through to production and the support that follows across frontend, backend, data and Azure infrastructure.
• Build clean React/TypeScript user experiences, well-designed APIs and services, sensible data models and deployments you can confidently stand behind.
• Build with AI and build AI: use agentic coding tools such as Claude Code, Copilot and similar to work smarter, while integrating models, retrieval patterns, agents, evaluation and guardrails into what we ship.
• Deliver AI-powered applications and internal products, moving between LAB3 platforms such as agent orchestration, FinOps and pricing tooling, and client-facing AI project delivery.
• Work closely with consultants, architects and clients to translate ambiguous business outcomes into concrete technical solutions and working software.
• Set a high engineering bar through mentoring, thoughtful reviews, pragmatic trade-off conversations, testing, observability and operational ownership.

The ideal candidate:

• Strong end-to-end full stack experience, typically 5+ years, with real depth across modern frontend, backend services, APIs, relational data and cloud deployment.
• Hands-on experience with React/TypeScript, PostgreSQL and Python, with the ability to design, ship, operate and improve production software.
• Practical Azure experience, or clear evidence you can get strong quickly across App Services, Functions, Storage, Identity and CI/CD.
• Demonstrated current use of AI development tooling in your day-to-day workflow, plus experience shipping a feature or product using LLM integration, RAG, agents or similar.
• Excellent collaboration and communication skills, including the ability to work directly with non-engineers and clients and mentor other developers.
• Resident, with full working rights, in Australia or New Zealand.

The tech

• React and TypeScript
• Python, APIs and backend services
• PostgreSQL and relational data modelling
• Azure App Services, Azure Functions and Azure Storage
• Azure Identity and CI/CD
• LLM integration, RAG, agents and agentic systems
• Prompt and context engineering
• LLM evaluation, guardrails and observability
• Claude Code, GitHub Copilot and similar AI development tools
• Microsoft Graph, Copilot Studio, Power Platform and the broader Microsoft/M365 ecosystem
