Research Engineer – Evals

You'll build the evaluation systems that tell us whether Firecrawl actually works. That sounds simple. It isn't. Our core promise — convert any URL into clean, structured, LLM-ready data reliably — is hard to measure rigorously across millions of different websites, formats, and edge cases. As we layer in models and agent workflows, the question "did that work?" gets harder, not easier.

This isn't an eval role where you inherit a framework and run benchmarks. You'll design the metrics, build the pipelines, generate the datasets, and own the feedback loop from output quality back to model and product decisions. If you care about what "good" actually means and have the engineering depth to measure it, this is the role.
