About the role
About the Role
Join the infrastructure team at a B2B web data extraction SaaS company, building systems that keep high-volume extraction reliable against websites with sophisticated anti-automation defenses. You will own production infrastructure end to end and help ensure web data remains accessible to AI applications.
What You'll Do
- Architect and operate proxy rotation, IP and session management, and isolated egress infrastructure at scale.
- Improve extraction success rates against aggressive anti-bot and anti-scraping defenses.
- Build and maintain browser and TLS fingerprint management, along with CAPTCHA and challenge-solving infrastructure.
- Monitor proxy-layer health and optimize its cost and operational efficiency.
- Diagnose intermittent failures across the stack and deliver lasting production fixes.
What We're Looking For
- More than 3 years of experience in adversarial web infrastructure, proxy-layer engineering, or web data extraction, including recent hands-on production work.
- Experience operating proxy rotation, IP and session management, egress isolation, and proxy economics for third-party web extraction.
- Production experience bypassing major anti-bot defenses and owning extraction success-rate metrics, as well as browser or TLS fingerprinting and CAPTCHA or challenge handling.
- Proficiency with Go and/or Python, plus networking fundamentals such as TCP/IP, HTTP/2, connection pooling, and proxy orchestration.
- Experience owning production systems end to end, including on-call responsibilities and observability tools such as Prometheus and Grafana.
- A practical, reliability-focused approach to complex adversarial systems, with a bias toward shipping, measuring, and iterating.
