Comtravo - Empowering Purposeful Business Travel

We are a team of travel experts, tech-enthusiasts and heroes of customer service - with the shared purpose to simplify business travel using an AI-based approach.
In our 6th year of existence, Comtravo is growing rapidly with now more than 250 colleagues, supported by top investors like Microsoft, Project A and Creandum.
We are currently on a strong growth path and looking for people to help us to build up our tech department and bring it to the next level.

Our two major web applications are developed for the internal or respectively external use of our travel agents and customers to book and manage their business trips. Both applications interact with our in-house-built booking engine with APIs to our suppliers.

We are using state-of-the-art technologies, such as ‘Natural Language Processing’  and machine learning techniques, to automate our fulfilment pipeline as well as customer and peer data from a database to customize the travels.

Our tech stack:

The frontend is built in Angular / Typescript. We have two major applications - one for our customers and one for our back-office team of travel agents.

The backend is primarily built in Node.js / Typescript and consists of around 20 major RESTful services plus around 60 microservices. We make heavy use of Docker and Terraform and are running on AWS. Services are coupled by events and run on AWS ECS and Lambda.

We invest heavily in shared components, libraries, automated tests, monitoring and sane interfaces. Together with a strong CI/CD pipeline we are able to release many times per day to production.
