Job Description

At Immfly, we create cool stuff: we develop a complete wireless entertainment platform, which we certify and install in commercial aircraft! We do this, using technologies we love: Linux, python/django/postgresql and javascript/angular, but always eager to try other languages and frameworks.

In aircraft servers, we use kvm and Docker, and Kubernetes, Openstack, Openshift for the Cloud. We do CI/CD, which is particularly challenging when your production servers are offline almost all time, and only get connection when the aircraft land! We use Ansible for some “typical” tasks and home-made stuff, for guaranteeing the service is up, no matter what happened in the aircraft (mainly power off or connection lost).

We use Elasticsearch, Logstash and Kibana for our business metrics and Fluentd, influxDB and Grafana for system monitoring (including aircraft).

We want our teams to be autonomous and self-organized based on goals: every team has all the elements to provide solutions to their problems without dependencies.

We prefer humble people willing and committed to do great things in a great team, rather than rockstars!!!

  • The API that runs inside the airplanes
  • Synchronization between the airplanes and the platform (distributed system)

Personal Qualities

  • Eager to learn new skills, continous improvement mindst and able to keep up with the latest technologies
  • Open Source user: You have basic knowledge of scripting on Linux systems
  • Proactive, with ability to adapt to different working styles and environments
  • Patient: Aircraft are not available for us when they fly, and we have short intervention windows, either in remote or on site interventions.
