About the Role

Join the infrastructure team at a growing AI-focused web data extraction company. You will build and operate systems that ensure reliable high-volume extraction against websites that actively resist automated access.

Responsibilities

  • Architect and manage proxy rotation, IP and session management, and isolated egress nodes at scale.
  • Improve extraction success against anti-bot and anti-scraping defenses.
  • Build and maintain browser and TLS fingerprinting, CAPTCHA, and challenge-handling infrastructure.
  • Monitor the reliability and cost efficiency of the proxy layer.
  • Investigate intermittent failures across the stack, resolve root causes, and maintain production systems.

Requirements

  • More than 3 years of experience in adversarial web infrastructure or proxy-layer engineering, with recent hands-on work in web extraction against active defenses.
  • Production experience designing proxy rotation, IP and session management, egress isolation, and proxy economics for third-party web extraction.
  • Experience bypassing major anti-bot systems in production and owning associated success-rate metrics.
  • Hands-on experience with browser and TLS fingerprinting and CAPTCHA or challenge handling at production scale.
  • Proficiency in Go and/or Python, plus networking fundamentals including TCP/IP, HTTP/2, connection pooling, and proxy orchestration.
  • Experience owning end-to-end production systems, including on-call responsibilities and observability tools such as Prometheus and Grafana.
  • Comfort working in complex, adversarial problem spaces and shipping, measuring, and iterating quickly.
