About the Role We are hiring a highly experienced Anti-Bot Engineer to design, build, and operate large-scale, resilient web scraping systems that extract high-quality data from heavily protected and constantly evolving web environments.

This is a senior-level, hands-on engineering role focused on building production-grade systems that operate at scale under adversarial conditions (anti-bot systems, dynamic rendering, frequent structural changes, and high-volume data extraction). You will be responsible for architecting and maintaining scraping infrastructure that must remain reliable, observable, and adaptable in real time. The role requires deep technical maturity, strong systems thinking, and the ability to operate independently in complex, ambiguous environments.

This position is best suited to engineers who have already built and operated large-scale distributed systems in production for several years and are comfortable owning mission-critical data pipelines end-to-end.

Responsibilities

• Design, build, and maintain large-scale Python-based scraping systems targeting highly protected websites (including Google-like environments).
• Architect resilient extraction systems capable of handling dynamic, JavaScript-heavy pages using browser automation and hybrid approaches.
• Continuously adapt systems to frequent changes in page structures, request flows, and anti-bot mechanisms.
• Build robust, production-grade data extraction pipelines with strong emphasis on accuracy, observability, and fault tolerance.
• Implement advanced strategies such as proxy rotation, fingerprinting, session management, and request routing to ensure stability at scale.
• Monitor system health, proactively detect anomalies, and debug complex production failures across distributed systems.
• Optimise scraping infrastructure for performance, cost efficiency, and reliability at scale.
• Collaborate with data engineering and product teams to ensure scraped data is structured, validated, and trusted.
• Operate and improve systems running continuously in cloud environments.
• Document system architecture, scraping logic, a
