Job summary

Cozycozy is seeking a Head of Data & AI in Paris to own the data function end-to-end. You will lead a small senior data and product team, while also doing hands-on work on the toughest problems, turning data into strategic business decisions across Revenue, Marketing, Product and Finance.

You will shape the data stack, drive AI initiatives, and partner with founders to scale a fast-growing travel-tech platform from the Operating Center mindset.

Qualifications

• 4+ years hands-on in Data & AI (DE, MLE, DS or similar), with experience leading scope, mentoring juniors, or owning a data function.
• Business partner: you turn needs from Revenue, Marketing, Product and Finance into a clear technical roadmap and make data legible to non-technical teams.
• Full-stack data and ML depth: you’ve built pipelines and medallion-style tables, ideally on a serverless AWS lakehouse (S3, Iceberg, Glue, Athena, dbt, Airflow/Dagster, Metabase). You’ve also shipped and maintained production ML (monitoring, retraining, CI/CD) and AI agents that automate manual work.
• Nice-to-have: Experience in travel or large-scale search and ranking, or in marketing data science (MMM, incrementality, causal methods).

Responsibilities

• Own the data & AI function end to end and report directly to the CEO.
• Balance leadership with hands-on technical work on the hardest problems.
• Act as a consultative partner to Revenue, Marketing, Product and Finance, distilling needs into a technical roadmap.
• Ensure data trust and push AI to replace manual, repetitive work; decide what to build vs. buy.
