What You'll Do

• Improve ranking and relevance for Firecrawl Search — from feature engineering to model training to production

• Build and tune models for learning-to-rank, query understanding, and LLM-driven retrieval

• Extend ML across Firecrawl's products — extraction quality, content classification, and evaluation of LLM-driven features

• Mine query logs and behavioral data at scale to find where our products win and where they fail

• Build the data pipelines that turn web-scale crawl and query data into training data and features

• Work hands-on with platform, search engineers and cloud DevOps to get models running fast and cheap in production

• Design and formulate our testing strategy — the A/B testing frameworks and offline evaluation the team ships against

• Partner on product launches across Firecrawl: define success metrics, run the experiments, and make the ship/no-ship call on evidence

• Report on how releases perform post-launch and turn the findings into the next iteration

What We're Looking For

• You've shipped ML models into production systems and owned them after launch — deploying, monitoring, and retraining them, not handing them off

• You have real ranking or relevance-modeling experience — learning-to-rank, recommendations, or search quality

• You're comfortable in large, data-heavy systems: query logs, pipelines, and datasets that don't fit in memory

• You write production-quality code (Python at minimum) and can work inside a real backend codebase

• You're rigorous about measurement — you've designed and analyzed A/B tests and know when a lift is real

• You can communicate results clearly to the team — what shipped, what moved, and what to do next

Nice to Have

• MLOps experience — MLflow, experiment tracking, model registries, or feature stores; Kubernetes is a plus

• Experience building or standardizing an experimentation framework at a previous company

• Experience with embedding models, vector retrieval, or LLM-based relevance evaluation

• Experience evaluating LLM outputs at scale — quality scoring, structured-extraction accuracy, or agent behavior

• Spark or similar large-scale data processing experience

What We're NOT Looking For

• A pure statistician or analyst who needs an engineering team to productionize their work

• Someone who wants to specialize narrowly and hand off everything else

• Someone who optimizes for process over shipping

A Note On Pace

We operate at an absurd level of urgency because the window for what we're building won't stay open forever. If that excites you, keep reading. If it doesn't, no hard feelings — but this role probably isn't for you.

Interview Process

Application Review — Send us your work and a quick note on why this excites you. Show us what you've built — search systems, indexing pipelines, ranking improvements. We care about what you've shipped, not where you went to school.

Intro Chat (~25 min) — A quick conversation to get to know each other before we go deep. We'll talk about what you've been working on, what drew you to Firecrawl, and what you're looking for in your next role. Time for your questions too.

Technical Chat (~45 min) — We'll dig into a real problem from our world; examples include: improving ranking quality with noisy relevance signals, designing the A/B test for a product launch, or building features from query logs — and talk through how you'd approach it. Come ready to think out loud; we care how you reason, not whether you memorized the answer.

Founder Chat (~25 min) — Culture, pace, ownership, and how you like to work. Time for your questions too.

Paid Work Trial (1-2 weeks) — Work with the team on a real, scoped piece of the product — paid at a contractor rate. It's the truest signal for both sides: you see what building at Firecrawl actually feels like, and we see how you ship. Remote-friendly, and we'll flex around your current commitments.

Decision — We move fast after the trial.

If you want your models ranking results for the whole web — and to see the impact in production the same week — you should join us.
