Senior Full Stack PHP​/JS Engineer - Core Team Remote Ireland

Overview

Hello 👋

Bring your strengths. Raise the bar. Shape the future.

We’re looking for a high-performing Senior Full Stack Engineer to join our team and help us build the future of Matomo — the world’s leading open-source web analytics platform that empowers users with full data ownership and built-in privacy.

This is more than a coding role — it’s an opportunity to tackle complex challenges at scale, work with a talented and driven team, and help shape how we do engineering as we grow. You'll be working in the heart of our platform — contributing to our core application and plugin ecosystem — and making a meaningful impact on hundreds of thousands of users worldwide.

If you thrive in large codebases, get energy from solving hard problems, and are excited by the chance to bring your ideas, passion, and expertise into a high-impact environment, we’d love to hear from you.

• Engineering Excellence
• Design, develop, and maintain robust, secure, and performant software at scale.
• Solve tough, technical problems that matter — from performance bottlenecks to architectural improvements.
• NAVIGATE and contribute to a mature, complex codebase — and leave it better than you found it.
• Write clean, well-tested, maintainable code that your future self and teammates will thank you for.
• Share your expertise through code reviews, pairing, and mentoring.
• Product Collaboration
• Work hand-in-hand with product managers and designers to deliver value that delights users.
• Challenge assumptions, refine ideas, and bring an engineering perspective to product discussions.
• Influence the roadmap by identifying impactful technical opportunities and trade-offs.
• Stay close to the “who” and the the "why" behind what we build — not just the "what."
• Shaping Our Growth
• Be a culture and quality multiplier — bring energy, curiosity, and a drive to raise the bar.
• Help evolve how we work — improving our engineering practices, processes, and standards.
• Take initiative in shaping solutions, identifying risks early, and driving delivery forward.
• As our company grows, you’ll help define what great engineering looks like at Matomo.

At Inno Craft, we’re building a more ethical, privacy-first digital world.

In Germany, Matomo is particularly popular with public institutions, universities, and companies that take GDPR compliance seriously. As part of our long-term growth, we are expanding our established Europe-based engineering team to support Matomo’s increasing adoption by enterprise and public-sector organisations across Europe.

We believe in openness, privacy, and transparency. Every month, our platform processes billions of data points — transforming complex information into intuitive, powerful reports that delight users.
