About the Opportunity:

Our client, a leader in Autonomous Vehicle Technology, is looking for a skilled  Network Security Engineer  to join their team for a 6+ months engagement. This project involves helping ensure the security of our customers, staff, systems, communications, and data, and supporting the implementation, maintenance and upkeep of network security systems.

Key Responsibilities & Deliverables:

This role is focused on the successful completion of specific tasks and deliverables. Your responsibilities will include:

This isn't a learning role—you need to be a subject matter expert.
  • Demonstrated ability to work autonomously and manage your own time effectively to meet project goals.
  • Experience with 3+ years of IT systems/application engineering/administration experience.
