Job Overview
We're looking for a strong Senior Full-stack PHP Software Engineer to join our team.
You'll primarily extend and enhance both the backend services and frontend interfaces that power our funnel and onboarding builder—work that directly impacts how thousands of customers create and manage their checkout experiences.
You'll be working in a mix of modern (object-oriented PHP, Laravel/Symfony, React) and legacy code, shipping features that matter while helping us incrementally modernize the stack.
You'll work alongside a team of skilled engineers who care about clean code, pragmatism, and shipping reliable, usable systems.
You'll have real impact on a system serving 65,000+ businesses, with the autonomy to incrementally modernize it.
The Team & Codebase
Editor 2.0 team is focused on our funnel and onboarding builder - a visual editor customers use to create their checkout experiences.
It's a complex UI with real-time preview, component management, and integrations with the rest of the platform.
The stack

React components for editor UI
We use PHPStan, PSR standards, and structured code reviews to maintain quality.

5+ years of professional experience building and maintaining web applications at scale
Strong PHP fundamentals: OOP, MVC, Laravel/Symfony or similar frameworks

Comfortable navigating legacy PHP codebases and modernizing them

Can write automated tests (PHPUnit, Jest, or similar)
Understanding of frontend basics: HTML, CSS, JavaScript
Familiarity with deployment pipelines, Git, and CI/CD
Experience of using AI Agents and implementing and building AI tools and Agents
Approach:




You default to shipping incremental improvements over big rewrites

You can explain technical tradeoffs to non-engineers
Nice to Haves
Experience building SaaS or e-commerce platforms

Comfortable navigating legacy and modern code
First 60 days
Independently own and ship medium-sized features across the stack
Provide helpful code reviews to the team
