Intro Tech

The Hotels Network (THN from now on) is a data platform for the hotel industry. Everything starts with our monitoring and media delivery Agent, which is currently embedded in more than 15.000 hotels and booking engines' websites worldwide. This agent is responsible for sending data to our platform and displaying our tools and widgets. These allow the hotels to harvest advanced user behavioral metrics, personalize their website and trigger UI widgets to boost conversion. Our tech stack consists of: Vanilla Javascript / Typescript, Go, PHP and Vue.js for our UI applications and dashboards.. Our platform runs on Amazon Web Services and Google Cloud. We store data in MySQL, Redis, Clickhouse and other storages. We love Kafka, asynchronous systems and building great products as fast as possible following the best practices.

Our monitoring Agent is built on top of Vanilla Javascript (transitioning soon to Typescript). It is the heart of everything we do. Performance is key, since it lives on someone else’s domain (our customers website). It deals with a lot of other services, and handles a lot of data.

Our backend consists of a series of mini/micro services built with PHP or Go embracing a Domain Driven Architecture. Testing is in our DNA and we conduct comprehensive unit and integration testing across the board. We embrace process automation wherever possible and ensure the quality and performance of our platform with SonarCloud, Sentry and Datadog.

Our solid data infrastructure is driven by our Data Engineering Team and relies on a modern, state-of-the-art platform supported by our DevOps Infra team. What makes THN stand out from any other player in this industry is our Data Science team, that designs and implements advanced ML/AI algorithms fueled by the massive data ingested by our Agent to help our clients predict their users behavior and improve their booking conversion. This position will play a pivotal role in ensuring our Data Science team gets the most valuable insights on our client’s users and target markets.
