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.
