Your responsibilities:

Maintaining and optimizing our cluster infrastructure

• Our platform runs fully containerized in the AWS cloud orchestrated by Kubernetes. We iterate on this architecture with approaches like Minikube on our local machines or isolated test clusters. All scripts used for deployments and cluster management are written with JavaScript and changes are handled like every other code change (Pull Request reviews, extensive automated tests). You can help us to extend this setup to run in a multi cloud, Multi-AZ environment. Furthermore, you can support us to keep up to date in the fast-moving world of cloud computing and own the selection of tools and processes to successfully implement DevOps in our company.

Improve and maintain our CI & CD processes

• We implement CI and CD with Jenkins Pipelines. All deployment code is written in modern and tested JavaScript. For every Pull Request we deploy into a fully isolated newly created Kubernetes namespace including automatically seeded databases. These environments are publicly available through their own unique URLs. This enables everyone in the team to do manual functional testing in addition to the automated Selenium test suite. You can help us maintaining and improving these systems and own the selection and implementation of new tools in this space.

What you can expect from us:

• Working in a diverse company culture shaped by fun, kindness and immensely committed and motivated people
• High autonomy and the option to thrive and grow in your preferred area of expertise
• Flexible time management
• Working in cooperative, multidisciplinary team structures with flat hierarchies
• Working within a team that has a great vibe and spirit, which shows not only when we are going out for our frequent team events or gatherings, but on a daily basis
• English as a company language
• No suits or ties — meaning, we don’t have a dresscode ;)
• Working in a vibrant area right in the middle of Hamburg (near Jungfernstieg) in the WeWork CoWorking Space (not only free coffee but also events like yoga, business talks or after-work drinks)
