About the Role
Reporting to: Michal Gondar, Head of Engineering
Location: UK Remote
Interviews: 2 Stages
Start Date: ASAP
What you’ll do at Adthena: As an 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.
Responsibilities:
- Design and maintain large-scale Python scraping systems that operate reliably against Google and other highly defended websites.
- 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.
Required Experience:
- Deep hands-on experience scraping Google or similarly protected platforms.
- 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.
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.
Our Core Values: All Adthenians are expected to align closely with our ‘Core Values’.
- Get Shit Done: We're big on taking action, owning our challenges, and finding solutions.
- Freedom with Responsibility: We take charge of results to recognition.
- 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.
