Full Stack Developer – Build Tools That Build the World

Melbourne, AU (Hybrid) | Engineering Team | Greenfield Projects + Real Impact

Want to write code that doesn’t just push pixels—but powers an entire industry?
At Buildxact, we’re helping builders and tradespeople run their businesses smarter, faster, and with way less chaos. We’re looking for a skilled Full Stack Developer to help us scale new greenfield features and evolve a robust, cloud-first SaaS platform trusted by thousands.

Why You’ll Love It Here:

Greenfield Energy – Help us build brand-new features and product lines from scratch
Real Tech, Real Users – Everything you ship gets used by builders IRL
Modern Stack – C#, .NET Core, GraphQL, Angular, Flutter, Azure—and AI-assisted coding tools like Copilot
Tight Team Vibes – Agile, cross-functional, collaborative—and no ego zone

What You’ll Be Doing:

Build and ship features that solve real problems for builders and small businesses
Maintain and evolve existing systems with clean, scalable, testable code
Contribute to roadmap planning and estimation with your tech expertise
Own your work—write it, test it, ship it, support it
Implement automated testing and CI/CD pipelines
Help shape product architecture and best practices
Collaborate with Product Managers, Designers, QA, and Support to ship value fast

You’ll Thrive If You Have:

3+ years building full-stack products in a SaaS, cloud-first environment
Strong grasp of C#, ASP.NET Core, EF Core, and the .NET ecosystem
Experience with Angular is ideal (but React or Vue works too—just be tight with Typescript/JS and CSS)
Bonus points for GraphQL (HotChocolate), Azure, and Flutter
You’re already using GitHub Copilot or similar tools and understand their strengths/limits
You take pride in writing quality code—but also know when “done” is better than “perfect”
A customer-first mindset and a natural urge to mentor and support others

The Buildxact Way:

We build like the people we serve: with simplicity, grit, and purpose. Our values are:
It’s yours to nail
Customer success is our success
Do what’s right
Keep it simple
