About the Role
Reporting to: Michal Gondar, Head of Engineering
Location: UK Remote
Interviews: 2 Stages
Start Date: ASAP
What youâll do at Adthena
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 naĂŻve approaches do not work, including dynamic rendering, anti-bot defences, frequent markup changes, and high-volume data collection.
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
Who we look for
Research shows men apply if they meet ~60% of the criteria, while women and underrepresented groups apply only if they meet all requirements. If you have the skills but don't meet every requirement, reach out â we'd love to explore how you could be a great fit!
Required Experience:
- 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
