Senior 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 Senior 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:
* 7+ years of experience delivering and building full-stack products in a SaaS, cloud-first environment, with a strong track record of ownership and technical leadership
* Deep expertise in C#, ASP.NET Core, EF Core, and the .NET ecosystem
* Proficiency with Angular is ideal (but React or Vue works too—backed by solid Typescript/JS and CSS fundamentals)
* Experience in GraphQL (HotChocolate), Azure cloud services, or Flutter is highly valued
* 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
