  • Work with infrastructure and deployment tools using Terraform and Docker

Requirements

  • Python - primary language for data processing and analytics
  • Go - high-performance backend services
  • Perl - some legacy & core components (Mojolicious) you may interact with
  • Terraform - infrastructure-as-code for our cloud environment
  • Docker - containerized development and production deployment
  • Experience with audio processing, telecom protocols (SIP, RTP), or test automation frameworks is a strong plus.
  • Good communication skills in English; German is a plus.
  • Ability to work in agile startup environments.
  • AWS / Cloud-based environment experience

Benefits & conditions

  • Work on cutting-edge automated testing and monitoring for real-time communication systems
  • Shape the analytics and intelligence layer of a unique deep-tech product
