Description du poste

As a Senior Anti-Bot Engineer, you will design, build, and operate large-scale, resilient web scraping systems, with a strong focus on Google and Google-like search environments. This role sits at the intersection of data engineering, reverse engineering, and systems reliability, and is critical to delivering accurate, timely, and trustworthy data at scale. You will work on complex scraping problems where naïve approaches do not work, including dynamic rendering, anti-bot defences, frequent markup changes, and high-volume data collection. We are leaders in adopting coding with AI tools. The role is ideal for someone who believes in agentic coding and would like to improve their skills. Responsibilities

• Design and maintain large-scale Python scraping systems that operate reliably against Google and other highly defended websites
• Build scrapers for dynamic, JavaScript-heavy pages using browser automation and hybrid approaches
• Continuously adapt to changes in page structure, request flows, and anti-automation mechanisms
• Engineer robust extraction pipelines that prioritise data accuracy, consistency, and observability
• Implement proxy, fingerprinting, and request-routing strategies to maximise stability and throughput
• Monitor scrape health, detect failures early, and rapidly debug production issues
• Optimise performance, cost, and latency across scraping infrastructure
• Work closely with data engineers, data scientists, and product teams to ensure scraped data is usable and trusted
• Document scraping logic and operational runbooks for long-term maintainability, Freedom with Responsibility: We take charge of results to recognition. We know that our hustle not only moves the needle for the company but also sets us up for personal success.
• Deliver Remarkable Quality: We care about exceeding expectations in the work we do and aim to always do our best work as individuals and as a team.
• Smart & Always Improving: We strive daily to expand our knowledge and become better at what we do.

Meet your teammates

You'll work closely with

• Strong professional experience with Python (or another main language, i.e. GoLang, Rust, JavaScript) including production-grade scraping systems
• Deep hands-on experience scraping Google or similarly protected platforms
• Solid understanding of HTTP, TLS, cookies, headers, redirects, and browser networking behaviour
• Experience with tools such as Playwright, Selenium, Puppeteer, or equivalent browser automation frameworks
• Strong knowledge of HTML parsing, DOM traversal, and data extraction techniques
• Experience handling rate limiting, CAPTCHA, IP rotation, and bot detection systems
• Comfortable working with asynchronous and concurrent scraping architectures
• Experience running scrapers at scale in cloud environments
• Strong debugging skills and ability to reason about complex failure modes
• Experience with headless browser fingerprinting and anti-bot evasion techniques

Nice To Have:

• Familiarity with containerisation and orchestration, such as Docker and Kubernetes
• Experience with distributed task systems and job queues
• Background in data quality monitoring and anomaly detection
• Experience working with search, advertising, or competitive intelligence data

What We Value:

• Pragmatic problem-solving in hostile and fast-changing technical environments
• High ownership of systems that run continuously and at scale
• A strong bias toward reliability, correctness, and observability
• Ability to explain complex technical behaviour clearly to non-specialists
• Curiosity about how large platforms evolve their defences and infrastructure. We're smaller than large-scale enterprises, offering more autonomy, less red tape, and accelerated growth.
