Senior Backend Engineer at Firecrawl

About Firecrawl: Firecrawl is the easiest way to extract data from the web. Developers use us to reliably convert URLs into LLM-ready markdown or structured data with a single API call. In just a year, we’ve hit millions in ARR and 50k+ GitHub stars by building the fastest way for developers to get LLM-ready data. About the Role: We’re looking for a Senior Software Engineer with deep experience in building scalable, reliable backend systems. You’ll work on the core services that make Firecrawl the go-to API for clean, structured web data. If you thrive in fast-moving environments, care deeply about clean abstractions, and love building high-performance systems, you’ll fit right in. What You’ll Do: Design, build, and maintain Firecrawl’s API layer (TypeScript, Express, Rust). Optimize and scale our PostgreSQL-backed data models for speed and reliability. Implement robust job queues, caching layers, and credit metering logic. Deploy and manage services in Kubernetes (GKE) with CI/CD. Improve monitoring, observability, and fault tolerance across our stack. Collaborate with the infra, browser, and product teams to bring new features to life. Help evolve our architecture to support 10x more scale and usage. Who You Are: 5+ years of experience building production-grade backend systems. Expert in TypeScript, Node.js, Express, Rust, and PostgreSQL. Comfortable designing APIs and working across services. Experience deploying and scaling apps in Kubernetes. Familiar with Redis, job queues, rate limiting, and background task processing. Enjoy working autonomously and pushing projects from idea to launch. Pragmatic, fast-moving, and excited about working on a large scale system. Bonus Points: Experience scaling queue-based APIs under high traffic. Familiarity with distributed systems and event-driven architectures. Past work on developer platforms or scraping tools. Open-source contributions. Previous startup experience or ex-founder.
