Senior PHP Engineer – Rebuild the Brain of an Industry
Hybrid | Sydney | Full-time
Up to $190k + super

Are you a Senior Engineer looking to work on a platform that genuinely powers an entire industry?

You’re probably not interested in just shipping code. You want to influence architecture, solve meaningful technical challenges, and contribute to rebuilding a system that sits at the heart of an entire sector. This role gives you the opportunity to do exactly that with a clear path toward feature leadership or future tech leadership, if that’s where you want to take it.

This is a start-up-style team within an enterprise environment. A high-performing, product-focused group with the autonomy to move fast, and the stability to do things properly. You’ll join a team of 35 engineers as we double in size to 65+, right at the point where we’re re-architecting a complex legacy monolith into a modular, scalable platform.

The product is a mission-critical ERP/CRM system automating business processes for the majority of Australia’s strata market — backed by a major financial technology company that’s quietly recruited senior talent from Google, Meta, and Amazon. It’s used every day by businesses that manage millions of homes and billions in funds. And now, it needs a senior engineer like you to help take it to the next level.

What’s In It For You?

• Real ownership over technical design, architecture, and delivery
  
  
• Opportunity to grow into Feature Lead or Tech Lead without giving up hands-on work
  
  
• Work on a platform with real-world impact — not just another SaaS tool
  
  
• A roadmap with both complexity and clarity: you’ll help untangle 1,000+ APIs and reshape the system
  
  
• Be part of a high-performing, collaborative team with flexibility and support
  
  

Tech Stack

• Languages & Frameworks: PHP8 (custom frameworks), JavaScript, Knockout.js, React (desirable)
  
  
• Databases: MySQL – performance tuning and indexing skills highly valued
  
  
• Cloud & Tools: AWS, profiling tools (e.g. DataTrace), cloud build tools, Karate for testing
  
  
• Security & Quality: Secure coding practices, unit testing, cybersecurity principles (desirable)
  
  
  
  

What You’ll Be Doing

• Build and modernise high-scale, PHP-based systems used by an entire industry
  
  
• Improve system design and help transition a legacy monolith into modular services
  
  
• Solve deep platform challenges across performance, scale, and reliability
  
  
• Write clean, secure, maintainable code — with a focus on long-term quality
  
  
• Contribute to front-end development with JavaScript (React experience is a bonus)
  
  
• Collaborate with senior engineers, product managers, and cloud specialists across multiple squads
