Offer description

Join to apply for the Senior Software Engineer role at The Onset

Build the future of one of Australia's most-loved online shopping experiences.

Picture this: you're part of a team where every line of code touches millions of customers—helping them browse, click, and get their favourite items delivered seamlessly. We're on the hunt for a Senior Engineer who lives and breathes PHP, loves Laravel, and isn't afraid to dive into React and AWS when the project calls for it.

This isn't just another "maintain the legacy code" role. You'll be at the heart of a major platform transformation—modernising core systems, building slick new features for customers and suppliers, and shaping how the platform scales for years to come. Your ideas won't sit in a backlog—they'll be powering the next generation of online shopping experiences.


Why This Role Rocks

* Hands‑on PHP/Laravel mastery: rebuild, refactor, and modernise one of the country's most recognisable e‑commerce engines.
* Full‑stack playground: jump between backend logic, React‑powered frontends, and cloud‑based integrations.
* Modernisation in motion: lead the migration from a legacy monolith to a flexible, service‑based architecture.
* Product partnership: work alongside designers, product managers, and QA to turn ideas into tangible features.
* Culture that clicks: join a low‑ego, highly skilled team that values learning, craftsmanship, and collaboration.
* Flexibility & perks: hybrid work, catered lunches, wellness programs, and a genuine focus on people.


Who You Are

* A PHP/Laravel pro with strong JavaScript/React chops.
* Pragmatic and outcome‑driven: you get why you're building something, not just how.
* Ownership‑mindful: you ship features, mentor peers, and drive solutions end‑to‑end.
* Collaborative and clear: you can explain technical ideas to non‑tech teammates without rolling your eyes.
* Curious and adaptable: always exploring better ways to build, integrate, and scale.

Bonus points if you've played with APIs, CI/CD pipelines, cloud environments, or high‑traffic e‑commerce systems.


The Tech You'll Be Playing With

* Backend: PHP, Laravel, MySQL, REST APIs
* Frontend: React, JavaScript, HTML, CSS
* Infrastructure: AWS, Docker, CI/CD pipelines
* Tooling: Jira, GitHub, Vercel
