Job description

  • Identify how bots are circumventing existing protections (e.g., API abuse, headless browsers, plugin vulnerabilities).
  • Develop and implement advanced anti spam measures tailored to the site's architecture (e.g., custom challenges, behavior analysis, honeypots, rate limiting, or integration with third party services like Cloudflare Turnstile).
  • Ensure the solution is lightweight, user friendly for genuine customers, and maintainable.
  • Provide documentation and a brief hand off to the client.

Requirements

  • Proven experience with WordPress security, specifically combating spam registrations and bot attacks.
  • Strong PHP and WordPress development skills (themes, plugins, hooks, REST API).
  • Familiarity with modern anti spam techniques (CAPTCHA variants, JavaScript challenges, IP analysis, browser fingerprinting, etc.).
  • Ability to reverse engineer how bots work and test your own solutions.
  • Portfolio of similar projects - please include links or descriptions of past work where you successfully reduced spam or secured a WordPress site.
  • Excellent communication in English (written and spoken).

Nice to Have

  • Experience with e commerce platforms (WooCommerce) and membership sites.
  • Knowledge of server level security (e.g., fail2ban, ModSecurity) and CDN configurations.
  • Contributions to WordPress core or security plugins.

Benefits & conditions

  • 100% remote - work from anywhere in your timezone.
  • Flexible hours - focus on delivery, not clock watching.
  • Direct collaboration with the client - no middlemen, no bureaucracy.
  • Impactful work - solve a decade old problem that actually matters to the business.
  • Potential for ongoing work - if results are strong, there may be additional security projects.
