• 10+ years of professional software engineering experience developing full-stack web applications in modern SaaS or tech environments.
• 10+ years of deep experience in full-stack engineering, with proven, hands-on mastery of PHP (strictly Symfony framework) and modern frontend development (preferably Svelte).
• Strong foundational programming skills, with the ability to write custom, low-level logic and clean architecture from scratch, rather than relying solely on framework abstractions, scripting and AI.
• Strong expertise with relational and non-relational databases (e.g., MySQL, MariaDB) and designing scalable REST/GraphQL APIs.
• Practical experience with cloud architecture (GCP), containerization (Docker), and modern CI/CD pipelines.
• A strong dedication to automated testing practices (unit, integration, e2e) and clean code principles.
• Native Dutch speaking, professional fluency in English, with the confidence to articulate technical ideas clearly to both technical and non-technical stakeholders.

Why you can't miss out on this opportunity

We take good care of our VONQies and that shows in our benefits package:

• A paycheck that fairly reflects the market and your experience, and of course, monthly pension contributions
• A MacBook for both business and private use!
• A fixed monthly phone expense allowance

• Flexible vacation days - that's right, we will not define a specific number, though a fair-usage approach applies to keep all team members happy! ️
• 100% reimbursement of your public transport expenses, so you can come to this lovely office worry-free.
• Still prefer to use your own vehicle? We offer a KM reimbursement, and parking is on us!
• A hybrid work model - work in the office and from home.
• Snacks, sodas, coffee, and everything you need for a "pick me up" break.
• Opportunities to grow your skills and take on exciting challenges in an entrepreneurial environment. No silos, no corporate red tape - share your ideas freely, even directly with the CEO
• A great, fun and young team in a dynamic, fast-growing international tech company - together we are stronger!
