Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Backend Infrastructure Engineer - **Company:** SIDEGUIDE TECHNOLOGIES INC. - **Location:** San Francisco, CA, United States - **Experience:** Experienced - **Salary:** $200,000.0 - $250,000.0 - **Contract:** Permanent contract - **Skills:** Software Debugging, Backend - **Published:** July 17, 2026 - **Apply:** https://www.indeed.com/viewjob?jk=c47f9a548535d5d6 ## About the Role Experience: 3+ years in backend, networking, or infrastructure engineering Visa: Must be legally authorized to work in the United States. We're not able to sponsor visas right now, though that may change down the line., * 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, * Someone who wants clean, well-defined problems only * Someone who avoids on-call or production ownership * Someone who needs the environment to be stable to do their best work ## Description 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. When Firecrawl "just works" on a site that tries hard to stop it, that's this team. You'll own real infrastructure from day one, not tickets in a backlog., * 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 ## Related Videos - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Using AI Without Losing Your Skills](https://www.wearedevelopers.com/videos/2045-using-ai-without-losing-your-skills) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [My journey into DevOps world - How it all started!](https://www.wearedevelopers.com/videos/545-my-journey-into-devops-world-how-it-all-started) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) ## Related Articles - [What’s the Difference Between Frontend and Backend Development?](https://www.wearedevelopers.com/magazine/240-what-s-the-difference-between-frontend-and-backend-development) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs) - [How to Become a Software Engineer Without a Degree in 2023](https://www.wearedevelopers.com/magazine/147-how-to-become-a-software-engineer-without-a-degree-in-2023) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers)
