At Lighthouse, we're on a mission to revolutionize commercial strategy as hospitality's most powerful AI platform. We take the world's largest hotel data network and transform it into real-time intelligence that drives action. We don't just deliver insights; we empower businesses to make decisions that move revenue.

With $370M in Series C funding and over $100M in ARR, we are scaling at lightspeed. Our 850+ teammates across 35 countries aren't just building software-they are leveraging cutting-edge AI to help hoteliers be the first to act. Tens of thousands of hotels across 185 countries trust Lighthouse to execute their commercial strategy, including every one of the top 15 global chains and thousands of independent hotels that consistently outperform their markets. With Lighthouse AI, the intelligence gets deeper. Decisions get smarter. Actions get faster. We help hoteliers be first to act.

As a Data Science Engineer, you will work in the Data Science Core team, a shared team supporting data science across Lighthouse. You will own work from an initial business question through to models and AI products that reach customers. The role combines hands-on internal consulting for teams without embedded data science support, readiness to support important data domains, and continuous research into AI applications for hospitality. You will work independently on projects while drawing on the support of Senior Data Scientists and MLOps Engineers.

• Partner with internal teams to contribute your data science expertise to projects
• Advise on and review data science work, or contribute hands-on to longer projects.
• Build, evaluate, and ship machine learning and AI models for customer-facing use.
• Bring models and AI products from an initial question through to production.
• Ramp up on important data domains to provide support and maintenance when needs arise.
• Research developments in advanced AI capabilities and experiment with their application in hospitality.
• Collaborate with stakeholders to determine whether a solution is ready for customer use.
