Senior Full Stack Engineer

For 30 years, BusinessCraft has been the software system backbone of Australia's residential construction industry. Our integrated platform runs operations, finance, and project delivery for some of Australia's largest volume builders. We’re owned by Vela APX, part of Canadian-listed Constellation Software Inc. (TSX: CSU). Join us to reshape and enhance home building for the 2030’s with the latest tech stack and AI.

We're building a unified web application that will replace today's separate desktop client, mobile app, and web services. This will be a full ERP replacement covering finance, operations, and project delivery. As our Senior Full Stack Developer, you'll set the patterns, tooling, and standards that the team builds on as we deliver a new product experience.

You'll work with AI-first tooling throughout the development lifecycle and help define how the team uses agentic coding tools responsibly across the entire application.

• Model ERP domains (finance, scheduling, project delivery, supply chain) into clean schemas, APIs, and workflows that replace existing desktop functionality

• Establish a shared architecture between web (React) and mobile (React Native) that maximises code reuse without ignoring platform conventions

• Collaborate on consolidation decisions: mapping legacy screens, workflows, and integrations into the new platform

• Contribute to team standards for AI-assisted development across frontend and backend, including prompt practices and review expectations
