Medior PHP Developer

Help build the future of fonQ’s E-commerce Platform
Are you a medior PHP developer who enjoys tackling complex challenges and building scalable, high-impact solutions? At fonQ, you’ll work on a high-traffic e-commerce platform serving millions of customers every day. Every improvement you make has a direct impact on how we deliver value to our customers and partners.

We’re in the middle of an exciting technical transition—from legacy systems to a modern Symfony-based architecture. This means you won’t just be adding features; you’ll actively help shape the technical foundation of our future platform. You’ll collaborate closely with experienced PHP and Shopify developers who’ll help you navigate our codebase—and together, contribute to architectural decisions, and challenge existing solutions to make them better.

You’ll work in an agile, Scrum-based environment, adapted to our context, where ownership, learning, and impact go hand in hand.

Your key responsibilities include, but aren’t limited to:

• Build, test, and maintain software that makes an impact—robust, scalable, and clean.
• Collaborate on designing smart solutions and challenge technical decisions.
• Conduct code reviews that raise the bar on performance, scalability, and maintainability.
• Create clear technical documentation, workflows, and best practices to keep the team aligned.
• Troubleshoot and solve challenging technical issues in both production and test environments.

Initiatives you might work on include:

• Smarter pricing & promotions: implement and optimize a new promo engine, enabling advanced promotion constructs across our Shopify platform.
• Scaling e-commerce operations: enhance dropshipping, warehouse systems, and marketplace seller integrations to make our backend faster, smarter, and ready for growth.
• Collaborate with an agency and our developers to implement a new ERP backbone and streamline all integrations and middleware for a solid, scalable foundation.

Job description

Here’s what makes a great fit for this role:

• Strong hands-on PHP framework skills: You have at least 5 years of experience with PHP and a modern framework such as Symfony or Laravel. You are confident in building robust integrations, middleware, and systems. You have a deep understanding of SOLID principles and know how to apply them in practice.
• You keep data flowing smoothly with SQL databases such as MySQL and PostgreSQL, and automate testing, deployment, and monitoring like a pro. You feel comfortable working with cloud platforms like GCP or AWS, whether using Compute Engine, Cloud Functions, Kubernetes, or equivalent services.
• You are experienced in working with event-driven architectures, building systems that communicate reliably through events and asynchronous workflows. You create and integrate well-structured APIs.
• E-commerce familiarity: If you’ve built products or systems for e-commerce, even better. Understanding how an e-commerce-first company works (like fonQ) will help you get started quickly. Bonus experience: working with complex data models and SaaS systems is a plus.
• Education: You think and work at a Bachelor’s or Master’s level.
• Communication: You explain technical concepts clearly, whether you’re talking to teammates or non-technical stakeholders.
• Personal qualities: Flexible, self-starter, hands-on, structured, solution-oriented, and always eager to learn.

IMPORTANT: Fluency in English and the ability to work in a hybrid setup are strict requirements. If you don’t meet these, please don’t apply, as we won’t be able to consider your application.

Lastly, what can you expect from fonQ?

• A flat hierarchical structure with room for innovation in a supportive team
• A welcoming and fonQ-y environment that fosters a culture of learning, exploration and problem solving
• A diverse work week and a dynamic e-commerce company with plenty of space for new ideas and initiatives, regardless of your role
• Unlimited and nicely priced lunch with a roof terrace
