What you’ll 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 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

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 – 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

Our Core Values

All Adthenians are expected to align closely with our ‘Core Values’.

What it means...

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. 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.
