  • Support the lifecycle management, decommissioning and modernisation of legacy network site infrastructure.

What makes you perfect for the role?

  • Demonstrated experience with mobile network deployment, site build, installation and commissioning standards, quality practices and lifecycle management.
  • The ability to act as a technical subject matter expert, provide clear direction to internal and external stakeholders, and work effectively across complex, multi-stakeholder environments.
  • Awareness of EME and ACMA regulatory requirements, Australian Standards and relevant Optus processes.
  • Strong understanding of network elements, configurations and associated data, together with technical knowledge of programming, IT infrastructure, databases, coding and macros.
  • Proven problem-solving, engineering, testing and analytical skills, including the ability to design test cases and develop practical workarounds.

The good stuff…
