Backend Infrastructure Engineer

About the role

You'll work on the infrastructure that makes Firecrawl fast and reliable against a web that constantly changes and fights back. This is deep systems work: keeping success rates high against sites with aggressive defenses, managing the proxy layer that powers reliable data collection at scale, and pushing throughput and reliability under heavy, spiky load.

Responsibilities

• Build and maintain the infrastructure that powers reliable data collection at scale
• Improve success rates against sites with aggressive defenses
• Own the health, rotation, and cost efficiency of the proxy layer
• Push throughput and reliability under heavy, spiky, real-world load
• Debug hard, intermittent failures across the stack and make them stay fixed

Requirements

• You've worked on networking, proxies, or high-throughput backend systems
• You're relentless about reliability and comfortable in messy, adversarial problem spaces
• You can own a system end to end and keep it healthy in production
• You move fast and close the loop - you'd rather ship, measure, and iterate than perfect on paper

Qualifications

Experience: 3+ years in backend, networking, or infrastructure engineering

Skills

Relentless about reliability, ability to own a system end to end, fast-paced environment, debugging hard, intermittent failures.
