About the role

What will you do at True Talent Solutions Partners?

About the Role

Join the infrastructure team at a B2B web data company, building systems that keep high-volume web extraction reliable when websites actively resist automated access. You will own production infrastructure end to end, with a focus on proxy operations, browser identity, and challenge handling.

What You'll Do

  • Architect and operate proxy rotation, IP and session management, and isolated egress nodes at scale.
  • Improve extraction reliability against anti-bot and anti-scraping defenses that change over time.
  • Build and maintain browser and TLS fingerprinting, CAPTCHA handling, and challenge-solving infrastructure.
  • Monitor proxy-layer health and cost efficiency, and improve its operational economics.
  • Investigate intermittent production failures, implement durable fixes, and support systems through on-call ownership.

What We're Looking For

  • More than 3 years of experience in adversarial web infrastructure or proxy-layer engineering, including production-scale work in the last two years.
  • Hands-on experience operating proxy systems for third-party web extraction, managing IP and session behavior, and working with browser or TLS fingerprints and CAPTCHA or challenge handling.
  • Experience building data-extraction infrastructure that handles adversarial defenses, rather than general backend, platform, or cooperative-networking systems.
  • Proficiency with Go and/or Python, plus networking fundamentals such as TCP/IP, HTTP/2, connection pooling, and proxy orchestration.
  • Experience owning production systems and on-call responsibilities, with observability tools such as Prometheus and Grafana.
  • Familiarity with relevant tools and systems such as headless browsers, JavaScript, Node.js, Redis, PostgreSQL, Kafka, Kubernetes, Docker, AWS, Terraform, and CI/CD.
