This position is an exciting chance to be directly mentored by experienced network engineers with cutting-edge hardware, protocols and DevOps tools. Your daily support will have a direct impact on our operational excellence and your contributions to automation, AI integration and tooling will define the future of our network. 

About You

  • Able to debug transport protocols (TCP/UDP)
  • Comfortable in Linux environments and have some programming or scripting knowledge
  • Enthusiastic about automation (for instance, using Python or similar tools) to simplify network operations, and open to AI-powered optimisations
  • Eager to learn and adapt, creative and open to feedback
  • Strong communicator; ready to interface with global teams and internal stakeholders
  • Organised and flexible, able to balance day-to-day support with longer-term projects
  • Have a collaborative spirit and thrive in a hands-on, team-driven environment
