Backend Infrastructure Engineer (Anti-Bot), Early Career

About the Role

Join an infrastructure team building reliable, high-volume web data extraction systems that operate against websites with active anti-bot defenses. You will own production systems end to end and help keep extraction reliable, efficient, and resilient as defenses change.

What You'll Do

• Architect and operate proxy rotation, IP and session management, and isolated egress infrastructure at scale.

• Improve extraction success against anti-bot and anti-scraping defenses, including browser and TLS fingerprinting and CAPTCHA or challenge handling.

• Monitor the reliability and cost efficiency of proxy infrastructure, and improve its operating economics.

• Investigate intermittent failures across the stack, implement fixes, and support production systems through on-call ownership.

What We're Looking For

• 0 to 3 years of backend infrastructure or distributed systems experience, with production-level experience building web extraction systems against adversarial defenses.

• Hands-on experience designing proxy rotation, IP and session management, egress isolation, browser or TLS fingerprinting, and CAPTCHA or challenge handling.

• Production experience with Go and/or Python, plus TypeScript or Node.js; PostgreSQL, Redis, Kafka, Prometheus, and Grafana.

• Experience with Kubernetes, Docker, AWS, Terraform, CI/CD, and networking fundamentals including TCP/IP, HTTP/2, connection pooling, and proxy orchestration.

• Ability to take ownership of infrastructure from design through production operation.
