Senior Frontend Software Engineer

trivago Analytics is an internal platform for business and marketing performance analysis - people within different marketing channels use the platform to make informed marketing spend decisions and it is used by other teams in trivago to analyse website traffic and visitor behaviour.
It consists of different controllers, dashboards, loading multiple charts on the same page, aggregating large amount of data for specific periods.
Correctness and performance are both critical for its success!

Our current code base is mainly a MVC application (Symfony PHP, jQuery, Highcharts, some Vue JS and React with Material UI), but we're moving towards separating front-end (via React portals) by serving it through a REST API. As part of this team you'll be working to implement new React components and help us transition to a modern Single Page Application that will also allow final users to customize their experience in the tool: new KPIs, filters and filterbars, custom views, custom aggregators, presentation mode for charts, etc
