Your tasks

At ADEX we are working on a real Big Data scale (we are talking about processing 400 TB of raw data in real time). We analyze billions of requests daily using one of the biggest Big Data clusters in Europe (120 local servers in Germany). We love automation, so we use tools like Puppet and Cloudera on a daily basis, and always try to minimize the manual interactions. Some of the new technologies that we are using right now are Spark, Hadoop, Kafka and Docker, although we try to stay up-to-date regarding the latest technologies by attending conferences and meetups.

We are looking for a Junior Infrastructure Engineer who, working closely with our Infrastructure Engineer, will take up the challenge of updating and maintaining our setup to continue improving our real time functionality. As a Junior Infrastructure Engineer, you help the engineering team with maintaining, growing and optimizing the existing fleet of Linux servers. This is a great opportunity to work with such a huge amount of data, work with some cutting-edge technologies and learn a lot from an experienced team of engineers in a Big Data environment.

Your profile

  • 1 year of experience using Linux operating system
  • First experience with system automation tools (Puppet, Ansible, or Chef)
  • Basic knowledge about the Hadoop and Spark Ecosystem
  • Experience in doing continuous integration and continuous delivery
  • Very good communication skills, fluent in English
  • Desire to move things forward and take ownership of the tasks
  • Experience with Docker, and Docker orchestration tools (k8s, Swarm, etc.) is a plus

Why you should work with us

  • You like challenging environments. Our technical work is very advanced since we are working with such amount of data
  • You want to learn from and work closely with our Infrastructure Architect, who built our system from scratch and has 10+ years of experience
  • You want to work with cutting-edge technologies like Docker and Docker Swarm in such a complex environment
  • Impact of your contributions is quickly felt by the team and yourself
  • We have a risk taking culture. Since what we are doing is very advanced, we are not afraid of trying and failing. And keep trying
  • Engineering culture: half of the company works in technical positions
  • Flexible working hours and independent work structure
  • Choose your own equipment
