• Collaborate with IP architects and security teams to align on policies, segmentation, and access control.
• Participate in capacity planning, traffic analysis, and latency optimization efforts.
• Maintain technical documentation, network diagrams, and SOPs for internal use.
• Mentor junior engineers and contribute to internal knowledge sharing.
• Coordinate with cross-functional teams to support network integration for new services or infrastructure rollouts.
