JD — the work
About the role
Adversarial web-extraction infrastructure at one of the fastest-growing developer-infrastructure companies in AI: keep high-volume extraction working against sites that actively fight back. Anti-bot evasion, proxy management, fingerprinting, challenge handling — real infrastructure ownership from day one at a company already at eight-figure revenue with a massive open-source following.
What you'll do
- Architect proxy rotation, IP/session management, and egress isolation at scale
- Keep success rates high against active anti-bot and anti-scraping defenses
- Build browser/TLS fingerprint management and challenge-handling infrastructure
- Own the health, cost efficiency, and economics of the proxy layer
- Debug hard, intermittent adversarial failures and make fixes stick
What they're looking for
- Production-scale experience building proxy infrastructure, anti-bot evasion, or web-extraction pipelines
- Deep systems debugging under adversarial conditions
