Engineering @ HolidayCheck 
One strategic pillar of HolidayCheck is to not have the biggest but the best team. To work towards that, we empower a culture of learning, feedback and ownership. Each team can decide which technology to use that is best suited to solve their current problem. Our teams are small and work agile. We are very open minded to try out new things and contribute to open source. In corona-free times, we host and sponsor meetups and conferences, as well as organizing a yearly internal IT conference which takes place at a resort, where our customers usually enjoy their vacation. 
 
Platform Engineering @ HolidayCheck is built on three pillars: 

• Build the company's web infrastructure platform with a clear commitment to automation,
• Integrate external services into our technology stack and
• Support feature teams throughout the whole product lifecycle, from design, through deployment, operation, and refinement of containerized services.

Platform Engineers are responsible for an environment with more than 1500 pods distributed across several Kubernetes clusters, more than 500 VMs and with more than 60 deployments a day.

Due to the current Swiss employment law regulations, we are only able to consider applicants who already have a valid work permit for Switzerland or are able to obtain a work permit without sponsorship from the company
