Our Mission: Why Lighthouse?

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 Lead Platform Engineer you will lead frontend platform initiatives that help all frontend work move faster without compromising quality. This is a hands-on builder and owner role focused on accelerating Lighthouse's migration from Ember to React, strengthening the design system, and improving the tooling, education, and guardrails that help engineers and AI agents produce high-quality frontend code.

You will turn broad goals into clear, well-documented plans; manage delivery and communicate progress; and partner with product engineers and solution architects to understand their needs and drive adoption. You will also own AI-assisted frontend tooling, improve the frontend harness so more engineers can contribute safely, and invest in the shared foundations, infrastructure, and delivery pipelines that support product teams, generative UI, and AI agents.
