About the Position

Backend Engineer – Data Acquisition

Ghent, Belgium

At Lighthouse, we’re on a mission to revolutionize commercial strategy as hospitality’s most powerful AI platform. We transform the world's largest hotel data network into real-time intelligence that drives action. With $370M in Series C funding and over $100M in ARR, we are scaling at lightspeed. Join our 850+ teammates across 35 countries as we leverage cutting-edge AI to help hoteliers be the first to act.

Responsibilities

You'll join our Crawler Engineering team as a Backend Engineer focused on data acquisition. Your role will involve:

• Designing and developing high-performance systems, mostly in Rust, that collect billions of data points from the web.
• Working on our in-house proxy layer and browser tooling: request routing, connection handling, and protocol-level behavior.
• Investigating hard crawler problems, testing alternative approaches when one gets blocked, and turning what works into robust, reusable systems.
• Building clear interfaces and guardrails so other teams and AI agents can use what you build reliably.
• Owning the quality of your code, including code written with AI assistance: tests, observability, and maintainability.
• Collaborating closely with crawler engineers, DevOps, and Security to ship secure and scalable solutions.

Requirements

• Hands-on experience building, deploying, and running production backend services in a cloud environment.
• Experience with a systems language such as Rust or C/C++, or a strong track record in another backend language and a drive to learn Rust.
• Solid grasp of how the web works under the hood: HTTP, TCP/IP, TLS, and proxies.
• R&D mindset: Curious about how browsers and network stacks work internally, comfortable with ambiguity, and prefer proving a hypothesis.
• Strong analytical and debugging skills: Comfortable with packet captures, profilers, and reading other people's source code.
• Excellent communication skills, sharing opinions, welcoming feedback, and working well in a team.
• Fluent in English.
