WordPress Security Developer; Anti-Spam Specialist

Location

Remote (Open to applicants in EU, Eastern Europe, and Australia)

Contract (Hourly or Fixed-price - negotiable)

Immediate

We manage a UK‑based prescription drug e‑commerce site built on Word Press. For over a decade the site has been flooded with spam user registrations despite using multiple plugins (mobile verification, math challenges, CAPTCHA, etc.). Spam accounts continue to bypass these measures, as shown in the attached screenshot. We need a developer who can think like an attacker, identify loopholes, and implement a robust, long‑term solution.

• Audit the current Word Press registration and login flows, including all security plugins and custom code.
• 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.

• Proven experience with Word Press security, specifically combating spam registrations and bot attacks.
• Strong PHP and Word Press 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 Word Press site.
• Excellent communication in English (written and spoken).

• Experience with e‑commerce platforms (Woo Commerce) and membership sites.
• Knowledge of server‑level security (e.g., fail2ban, Mod Security) and CDN configurations.
• Contributions to Word Press core or security plugins.

• 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.

To apply, submit the following:

• Resume / CV highlighting relevant experience.
• Portfolio of similar anti‑spam or Word Press security projects (links or PDF).
• Cover letter (optional but encouraged) – briefly describe your approach to diagnosing and solving spam issues like the one described.

Applications reviewed on a rolling basis. We're looking for someone who can start within a week.
