Mid/Senior Backend Developer

Join Numiko, where your work truly means something. You’ll help craft digital solutions for change-makers - from cultural institutions to charities to public-sector projects - working on high-traffic, performance-critical systems that touch lives daily.

You’ll collaborate closely with back-end and front-end developers, designers, and project managers to build secure, scalable, and fast-performing platforms, mostly in PHP and Drupal. This role is perfect for someone who loves tackling technical complexity while contributing to meaningful digital experiences.

• Passionate: You care deeply about building high-performance systems that matter.
• Diligent: You own the quality, security, and longevity of your work.
• Problem-solver: You rise to challenges with smart, scalable solutions-and know when collaboration makes it even better.
• Curious: You stay curious about technology, trends, and better ways of working-ready to share what you learn.

We’re looking for someone who brings:

• Advanced PHP skills with a focus on maintainable, framework-based development
• Experience optimizing performance and handling large-traffic websites
• A solid understanding of web-security best practices and automated threat prevention
• Expertise in server resource management and performance tuning
• Proficiency in Git version control
• Clear, confident communication across all stakeholders
• Sharp estimation and task-planning abilities
• Experience mentoring or collaboratively working in a development team
• Familiarity or hands-on experience with Drupal

If you can do the following, we'd love to hear about it. But it's not a must-have.

• Cloudflare experience
• Exposure to AI technologies
• Experience with Python/Django
• Familiarity with Vue.js
