Senior PHP Developer – Build & Modernise a Scaling Platform

Join a growing tech business at a key transformation point - where speed, automation, and modernisation are the focus.

You’ll work closely with the CTO, founders, and a small engineering team to ship new features, improve existing systems, and help drive a migration from legacy PHP (CakePHP) to a modern framework like Laravel or Symfony.

This is a hands-on role with real impact—ideal for someone who enjoys solving problems, working at pace, and contributing to technical direction.

What you’ll do:

  • Build and deliver new features across a PHP/React stack

  • Contribute to system modernisation and migration

  • Help improve engineering efficiency using AI tools

  • Work closely with product and leadership to ship quickly

What we’re looking for:

  • Strong PHP experience (Laravel/Symfony ideal)

  • Experience working with or modernising legacy systems

  • Exposure to React or modern frontend frameworks

  • Someone reliable, proactive, and delivery-focused

  • Interest in AI tools and improving developer productivity

Why join:

  • High-impact role in a scaling business

  • Work directly with founders and decision-makers

  • Real ownership and influence on technical direction

  • Hybrid working + great office perks (gym, pool, food culture) 

If you’re looking for a role where you can build, influence, and move fast—this is it. Reach out to reema@theonset.com.au for more details.
