  • Leading continuous improvement, by automating the installation, configuration and maintenance of services on our platform
  • Assisting in the architectural design of new services and making them operate at scale

  • A thorough, protocol-level understanding of TCP/IP, HTTP, and TLS
  • Experience with package management on Linux systems (we use Debian)
  • Comfortable with Open Source configuration management and orchestration tools (Puppet, Ansible, Chef, SaltStack)
  • Good Linux system level skills
  • History of automating tasks and processes, identifying process gaps, and finding automation opportunities
  • Strong English language skills and ability to work independently, as an effective part of a globally distributed team

Additionally, we’d love it if you have:

  • Experience with the use, maintenance and configuration of monitoring, metrics and logging infrastructure (Prometheus, Grafana, ELK, Icinga/Nagios, etc.)
  • Experience with high-performance HTTP(S) caching proxy software, such as Varnish, Envoy Proxy, Apache Traffic Server, Nginx or HAProxy
  • Experience with Linux kernel tuning for high traffic loads
  • Developing/contributing to Free and Open Source software, or being part of an open-source community
