Job Description

Senior PHP Developer (German, French, or Spanish speakers)

Help us build and support WPML – the leading multilingual plugin powering 1.5M+ websites.

We’re looking for smart, curious developers who enjoy solving real problems and want to grow fast. This role mixes development and support: you learn the product deeply, help clients, and improve WPML based on what you discover.

Indicators You're a Great Fit:

  • You have strong PHP experience and are motivated to keep sharpening your skills.
  • Expert in WordPress, including setting up a local dev environment, navigating the admin backend, adjusting settings, and having basic development knowledge.
  • You’re experienced in debugging issues, tracing root causes, and suggesting meaningful product improvements.
  • Believe in writing tests and clean, reliable code.
  • Enjoy investigating problems and fixing root causes.
  • You’re fluent in English, and French, German, or Spanish.
  • You communicate clearly and genuinely, and you enjoy helping others.

Nice to have experience with:

  • React 
  • MySQL
  • Customer support

What You'll Do

  • Deliver new features and strengthen existing components.
  • Support WPML clients and solve technical problems.
  • Strengthen your expertise in PHP, WordPress, testing, performance, and modern tooling.

Why This Role Works Well for Developers

  • Direct connection to real problems: You see issues before they turn into technical debt and can fix them properly.
  • Stronger product intuition: Support cases reveal edge cases, integrations, and workflows you won’t discover from code alone.
  • Your code has an immediate impact: You’ll build features for one of the most used multilingual solutions in the world and help improve its reliability.
  • You influence the roadmap: What you learn from users feeds directly into better architecture and long-term fixes.

If you want to learn fast, make a visible impact, and join a global team that cares about quality – apply today, and we’d love to meet you!
