About The Position

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.

At InnoCraft, we’re building a more ethical, privacy-first digital world. As the leading open-source web analytics platform, Matomo powers over 1 million websites and apps in 190+ countries, offering organisations the insights they need while maintaining full data ownership and user trust. In Europe, 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. Matomo is available in 50+ languages and supported by a global, fully remote community with strong hubs in New Zealand and Europe.

Requirements

• You have 8+ years’ experience in software engineering, including full-stack development.
• You’re highly competent in PHP and JavaScript, and not afraid of diving deep into a large legacy codebase.
• You bring a structured approach to solving complex problems, and thrive in systems with many moving parts.
• You’re passionate about building products and not just writing code — you want your work to have real impact.
• You’re thoughtful, pragmatic, and care deeply about quality, user experience, and craftsmanship.
• You collaborate with humility, communicate clearly, and enjoy learning from others as much as teaching.
• You’re sure-footed in a remote environment, and able to build effective working relationships with people on the other side of the world.

Nice To Haves

• Experience with Vue.js or modern JS frameworks
• Familiarity with large-scale open-source systems
• Contributions to community projects or mentoring others
• Comfort with Linux CLI, databases (MySQL), and Git/GitHub workflows

Responsibilities

• 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.
• 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 "why" behind what we build — not just the "what."
• 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.

Benefits

• Remote work (save many hours on commute, and save money)
• Budget for co-working space or work from home
• Home office equipment supplied
• Flexible hours
• 25 days of paid holidays per year plus your national public holidays
• Sick leave
• Health Insurance: Your Well-being, Our Priority
• A huge “playground” to grow your skill set
• Volunteering Day: Empower Your Impact
• Bereavement Leave for Pets: Compassion Beyond Boundaries
• Training Opportunities
• Mental Health Support Services
• Opportunity to have an immediate impact on a product that is used by more than 1 million websites and almost 2% of the whole Internet
• Opportunity to work in a customer obsessed business, dedicated to building high-quality software with a strong mission of helping people grow their web projects while keeping full control of their data
