About the role
This role tackles the complex challenges of web scraping at scale against platforms like Google, Amazon, and Walmart. As a Senior Software Engineer, you will deeply investigate why requests get blocked, decipher detection mechanisms, and design methodical, repeatable solutions rather than relying on trial-and-error fixes. Over your first 3–6 months, you will build a greenfield agentic environment capable of automatically evaluating targets and anti-bot systems to reliably diagnose detection triggers.
What you'll do
- Analyse how anti-bot systems (DataDome, Cloudflare Turnstile, Kasada, PerimeterX, Akamai) detect and block requests, and engineer systems to bypass them.
- Formulate scientific hypotheses, run tests, and turn isolated bypass breakthroughs into durable, repeatable engineering processes.
- Design and build a greenfield agentic environment that proposes and executes tests on anti-bot behavior and mitigations.
- Work independently on deep technical challenges while pulling in knowledge and collaborating across the wider engineering team.
- Provide technical depth and support during major operational incidents.
What you bring
- Deep foundational knowledge of internet protocols and browser behavior: HTTP, TLS fingerprinting, proxies, headers, and cookies.
- Methodical and scientific approach to problem-solving and debugging.
- Hands-on proficiency with Node.js, TypeScript, and Python across backend architectures (Postgres, Redis/Valkey, MongoDB, Puppeteer/Camoufox, Kubernetes).
- Skill at steering and directing AI coding agents (Claude, Codex, etc.) with high precision.
- Background in scraping, anti-bot/web security engineering, reverse engineering, or rigorous technical research.
